【php常用方法】

1、根据生日算年龄

public static function calcAge($birthday){

    $age=0;
   if (!empty($birthday)) {
        if($age === false){
             return 0;
        }

        //explode()函数:把字符串打散为数组 2019-8-2 打散为 2019 8 2
        //list() 函数用于在一次操作中给一组变量赋值 $y1=2019 $m1=8 $d1=2

        list($y1, $m1, $d1) = explode("-", date("Y-m-d", $age));
        list($y2, $m2, $d2) = explode("-", date("Y-m-d"), time());

        $age = $y2 - $y1;
        if ((int) ($m2 . $d2) < (int) ($m1 . $d1)) {
                $age -= 1;
        }
    }
    return $age;
}

2、验证码

 public static function Is_password($value, $minLen = 5, $maxLen = 16) {
        $match = '/^[\\~!@#$%^&*()-_=+|{}\[\],.?\/:;\'\"\d\w]{' . $minLen . ',' . $maxLen . '}$/';
        //trim() 函数移除字符串两侧的空白字符或其他预定义字符
        $v = trim($value);
        if (empty($v)) {
            return false;
        } else {

            //preg_match()函数搜索字符串模式，如果模式存在返回true，否则返回false

            return preg_match($match, $v);
        }
    }

3. 验证手机

   public static function Is_mobile($value, $match = '/^[(86)|0]?(13\d{9})|(15\d{9})|(18\d{9})$/') {
        $v = trim($value);
        if (empty($v))
            return false;
        return preg_match($match, $v);
    }
 

4、验证座机

 

 public static function Is_telephone($value, $match = '/^(0[0-9]{2,3}-)?([2-9][0-9]{6,7})+(-[0-9]{1,4})?$/') {
        $v = trim($value);
        if (empty($v))
            return false;
        return preg_match($match, $v);
    }

5、 时间格式判断处理方法

 

public static function Is_time($timeStr) {
        if (empty($timeStr))
            return false;
        $match = '/^\d{4}-\d{2}-\d{2} \d{2}:\d{2}:\d{2}$/s';
        return preg_match($match, $timeStr);
    }

6、查找img标签处理方法

 public static function exist_img($img) {
 
        if (empty($img))
            return false;
        $match = '/]+>/is';
        return preg_match($match, $img);
    }

7、判断数字处理方法

   public static function Is_number($number, $start = 1, $limit = NULL) {
        if (empty($number))
            return false;
        $match = '/^\d{' . $start . ',' . $limit . '}$/is';
        return preg_match($match, $number);
    }

8、判断是否为正确邮箱地址

 public static function Is_email($email) {
        return preg_match("/^([a-zA-Z0-9_-])+@([a-zA-Z0-9_-])+(.[a-zA-Z0-9_-])+/", $email);
    }

9、判断url处理方法

  public static function Is_Url($url) {
        if (empty($url))
            return false;
        $match = '/www.[a-zA-z0-9]+.[a-zA-z0-9]+/is';
        return preg_match($match, $url);
    }

10、生成公共的TOKEN方法   @param unknown $data 要加密的数据   @return string 返回加密结果

    public static function create_token($data) {
 
        //生成全局加密KEY      mt_rand() 使用 Mersenne Twister 算法返回随机整数
        $token_key_1 = mt_rand(10000000, 99999999); //前8位KEY
        $token_key_2 = mt_rand(10000000, 99999999); //后8位KEY
        if (empty($_SESSION['TOKEN_KEY_1'])) {
            $_SESSION['TOKEN_KEY_1'] = $token_key_1;
        }
        if (empty($_SESSION['TOKEN_KEY_2'])) {
            $_SESSION['TOKEN_KEY_2'] = $token_key_2;
        }
        return md5($_SESSION['TOKEN_KEY_1'] . $data . $_SESSION['TOKEN_KEY_2']);
    

11、下载文件处理方法

    public static function download($path, $fileName, $downName = '') {
 
        $path = trim($path);
        $fileName = trim($fileName);
 
        //文件名转码  iconv（）转码函数
        $fileName = iconv('utf-8', 'gb2312', $fileName);
 
        //设置路径   strlen（）函数返回字符串的长度：  substr() 函数返回字符串的一部分
        if (substr($path, strlen($path) - 1, strlen($path)) != '/') {
 
            $file = $_SERVER['DOCUMENT_ROOT'] . $path . '/' . $fileName;
        } else {
 
            $file = $_SERVER['DOCUMENT_ROOT'] . $path . $fileName;
        }
        //die($file);
        file_exists($file) || die('下载文件不存在');
 
        $file_size = filesize($file);
 
        //读取文件
        $fp = fopen($file, "r");
        $buffer_size = 1024;
        $cur_pos = 0;
 
        $downName = empty($downName) ? $fileName : $downName;
 
        header("Content-type: application/octet-stream");
        header("Accept-Ranges: bytes");
        header("Accept-Length: $file_size");
        header("Content-Disposition: attachment; filename=" . $downName);
 
        //刷出缓冲区
        ob_clean();
        flush();
 
        //输出文件
        while (!feof($fp) && $file_size - $cur_pos > $buffer_size) {
            $buffer = fread($fp, $buffer_size);
 
            echo $buffer;
 
            $cur_pos += $buffer_size;
        }
 
        $buffer = fread($fp, $file_size - $cur_pos);
 
        echo $buffer;
 
        fclose($fp);
 
        return true;
    }

        $url = $_SERVER['REDIRECT_URL'] . "?" . http_build_query($parameter); //获取当前url
        //上下翻页字符串
        $upRow = $currentPage - 1;
        $downRow = $currentPage + 1;
        //$pageShow = $totalRows."条记录/共".$totalPage."页 ";
        if ($nowCoolPage == 1) {

        }
 
        $pageShow .= $upRow > 0 ? "上一页" : "";
 
        // 1 2 3 4 5  
        //add by baoxianjian 22:46 2015/4/2 分页点到5时，就从5到9
        $i_start = 1;
        $i_end = $listRows;
        if (ceil(($currentPage + 1) / $listRows) > $nowCoolPage) {
            $nowCoolPage++;
            $i_start = 0;
            $i_end = $listRows - 1;
        }
 
        for ($i = $i_start; $i <= $i_end; $i++) {
            $page = ($nowCoolPage - 1) * $listRows + $i;

        $self = new self();
        $self->dispatchJump($msg, 0, $config);
        die;
    }

15、成功转跳模板

 public static function success($msg, $jumpUrl = '', $title = '成功提示', $wait = '', $TplUrl = '', $close = '') {
        $TplUrl !== '' && $config['TplUrl'] = $TplUrl;
        $jumpUrl !== '' && $config['jumpUrl'] = $jumpUrl;

        $self = new self();
        $self->dispatchJump($msg, 1, $config);
    }

16、转跳提示模板

    private function dispatchJump($msg, $status, $config) {
        $sTpl = new STpl();
        isset($config['title']) || $config['title'] = '提示信息';
        isset($config['TplUrl']) || $config['TplUrl'] = "common/dispatchJump/dispatch_jump.html"; //检查模板是否存在
        isset($config['closeWin']) && $config['jumpUrl'] = 'javascript:window.opener=null;window.close();'; //是否关闭窗口
        $config['status'] = $status; //设置状态
        if ($status) {//成功
            $config['msg'] = $msg; //成功信息	
            isset($config['waitSecond']) || $config['waitSecond'] = '1'; //成功操作后默认停留1秒
            // 默认操作成功自动返回操作前页面
            isset($config['jumpUrl']) || $config['jumpUrl'] = $_SERVER["HTTP_REFERER"];
        } else {//错误
            $config['msg'] = $msg; //错误信息
            isset($config['waitSecond']) || $config['waitSecond'] = '5'; //失败操作后默认停留5秒
            // 默认操作成功自动返回操作前页面
            isset($config['jumpUrl']) || $config['jumpUrl'] = "javascript:history.back(-1);";
        }
        echo $sTpl->render($config['TplUrl'], $config);
        die;
    }
 

17、判断异步请求处理方法

    public static function isAjax() {
        if (isset($_SERVER['HTTP_X_REQUESTED_WITH'])) {
            if ('xmlhttprequest' == strtolower($_SERVER['HTTP_X_REQUESTED_WITH']))
                return true;
        }
        //如果参数传递的参数中有ajax
        if (!empty($_POST['ajax']) || !empty($_GET['ajax']))
            return true;
        return false;
    }
 

18、判断post提交

  public static function isPost() {
        if ($_SERVER['REQUEST_METHOD'] !== 'POST') {
            return false;
        }
        return true;
    }

19、判断get提交

 public static function isGet() {
        if ($_SERVER['REQUEST_METHOD'] !== 'GET') {
            return false;
        }
        return true;
    }

20、格式化打印数组处理方法

 public static function P($arr) {
        echo "
";
        print_r($arr);
    }
 
  
21、读取配置数组文件处理方法
 
  
 public static function C($name) {
        require $_SERVER["DOCUMENT_ROOT"] . '/config_array.php';
        return $config_array_php_file[$name];
    }
 
  
22、过滤解释数组方法
 
  
    public static function html_arr($arr) {
        foreach ($arr as $k => $v) {
            if (!is_array($v)) {
                $arr[$k] = htmlspecialchars($v, ENT_QUOTES);
                $arr[$k] = trim($arr[$k]);
            } else {
                $arr[$k] = self::html_arr($v);
            }
        }
        return $arr;
    }
 
  
23、 encode http请求过滤，防注入、XSS等安全处理    @param $string 可以为字符或者数组   @return $string 可以为字符或者数组
 
  
    public static function httpFilter($string) {
        $string = str_replace(array('sleep('), array('_sleep(_'), $string);
        if (is_array($string)) {
            foreach ($string as $key => $val) {
                $string[$key] = self::httpFilter($val);
            }
        } else {
            $string = trim($string);
            $string = htmlspecialchars($string);
            $string = self::straddslashes($string);
        }
        return $string;
    }
 
    private static function straddslashes($string) {
        if (!get_magic_quotes_gpc()) {
            return addslashes($string);
        } else {
            return $string;
        }
    }
 
 
  
   24、decode http请求过滤，防注入、XSS等安全处理 返解码，最好不要使用          使用编辑器那么后面会自己写ubb规则来处理
 
  
public static function deHttpFilter($string) {
        if (is_array($string)) {
            foreach ($string as $key => $val) {
                $string[$key] = self::deHttpFilter($val);
            }
        } else {
            $string = htmlspecialchars_decode($string);
            $string = stripslashes($string);
        }
        return $string;
    }a
 
  
25、ubbl转html xheditor UBB使用   @param unknown_type $sUBB   @return string|mixed
 
  
 public static function ubb2html($sUBB) {
        $sHtml = $sUBB;

                $cnum++;
                $arrcode[$cnum] = $match[0];
                return "[\tubbcodeplace_" . $cnum . "\t]";
            }
 
        }

        if ($tlength > $length) {
            $str = $str . $postfix;
        }
        return $str;
    }

            return substr($addr, 0, $idx) . $suffix;
        } else {
            return $addr;
        }
    }

            } elseif (getenv('HTTP_X_FORWARDED_FOR') && strcasecmp(getenv('HTTP_X_FORWARDED_FOR'), 'unknown')) {
                $onlineip = getenv('HTTP_X_FORWARDED_FOR');
            } elseif (getenv('REMOTE_ADDR') && strcasecmp(getenv('REMOTE_ADDR'), 'unknown')) {
                $onlineip = getenv('REMOTE_ADDR');
            } elseif (isset($_SERVER['REMOTE_ADDR']) && $_SERVER['REMOTE_ADDR'] && strcasecmp($_SERVER['REMOTE_ADDR'], 'unknown')) {
                $onlineip = $_SERVER['REMOTE_ADDR'];
            }
            preg_match("/[\d\.]{7,15}/", $onlineip, $onlineipmatches);
            $_SGLOBAL['onlineip'] = $onlineipmatches[0] ? $onlineipmatches[0] : 'unknown';
        }
        if (!$format) {
            $ip = $_SGLOBAL['onlineip'];
        } else {
            $ip = sprintf('%u', ip2long($_SGLOBAL['onlineip']));
        }
        return $ip;
    }
 
  
31、格式化大小函数   @param $size 为文件大小  @return 文件大小加单位
 
  
  public static function formatsize($size) {
        $prec = 3;
        $size = round(abs($size));
        $units = array(0 => " B ", 1 => " KB", 2 => " MB", 3 => " GB", 4 => " TB");
        if ($size == 0)
            return str_repeat(" ", $prec) . "0$units[0]";
        $unit = min(4, floor(log($size) / log(2) / 10));
        $size = $size * pow(2, -10 * $unit);
        $digi = $prec - 1 - floor(log($size) / log(10));
        $size = round($size * pow(10, $digi)) * pow(10, -$digi);
        return $size . $units[$unit];
    }
 
  
32、验证目录名是否有效 (只允许输入数字和字母)     @param $dirname 目录名     @return true or false
 
  
public static function isdir($dirname) {
        $patn = '/^[a-zA-Z]+[a-zA-Z0-9]+$/';
        return preg_match($patn, $dirname);
    }
 
  
33、创建目录     @param $path 目录路径 如：e:/work/yii/test    @return true or false
 
  
public static function makePath($path) {
        return is_dir($path) or ( self::makePath(dirname($path)) and mkdir($path, 0755));
    }
 
  
34、 删除目录   @param $path 目录路径 如：e:/work/yii/test    @return true or false
 
  
    public static function rmDir($path) {
        return @rmdir($path);
    }
 
  
35、获取文件内容   @param $filename 目录路径 如：e:/work/yii/test.html   @return 字符串->文件内容
 
  
 public static function sreadfile($filename) {
        $content = '';
        if (function_exists('file_get_contents')) {
            @$content = file_get_contents($filename);
        } else {
            if (@$fp = fopen($filename, 'r')) {
                @$content = fread($fp, filesize($filename));
                @fclose($fp);
            }
        }
        return $content;
    }
 
  
36、写入文件内容     @param $filename 目录路径 如：e:/work/yii/test.html     @param $writetext 写入文件内容    @param $openmod 打开文件类型 默认为'w'表示写入      @return true or false
 
  
  public static function swritefile($filename, $writetext, $openmod = 'w') {
        if (@$fp = fopen($filename, $openmod)) {
            flock($fp, 2);
            fwrite($fp, $writetext);
            fclose($fp);
            return true;

            //runlog('error', "File: $filename write error.");
            return false;
        }
    }
 
  
37、 产生随机数    @param $length 产生随机数长度    @param $type 返回字符串类型    @param $hash  是否由前缀，默认为空. 如:$hash = 'zz-'  结果zz-823klis   @return 随机字符串 $type = 0：数字+字母   $type = 1：数字 $type = 2：字符

        } else {
            return 0;
        }
    }
 
 
  
70、替换敏感词汇  @param unknown_type $word   @return string
 
  
public static function filterWords($word) {
        $filterwords = file(dirname(__FILE__) . DIRECTORY_SEPARATOR . 'filedata' . DIRECTORY_SEPARATOR . 'filterwords.txt');
        foreach ($filterwords as $k => $v) {
            $filterwords[$k] = trim($v);
        }
        $str = @implode('|', $filterwords);
        $content = preg_replace("/$str/i", '***', $word);
        return $content;
    }
 
 
  
71、 获取邮箱URL   @param  $email     @return string
 
  
 public static function getMailUrl($email) {
        if (self::validEmail($email)) {
            $urlarr = array(
                'qq.com' => 'http://mail.qq.com',
                'vip.qq.com' => 'http://mail.qq.com',
                'foxmail.com' => 'http://mail.foxmail.com',
                'vip.163.com' => 'http://mail.vip.163.com',
                '163.com' => 'http://mail.163.com',
                '188.com' => 'http://mail.188.com',
                '126.com' => 'http://mail.126.com',
                'yeah.net' => 'http://mail.yeah.net',
                'tom.com' => 'http://mail.tom.com',
                'gmail.com' => 'http://mail.google.com',
                'gmail.com' => 'http://www.gmail.com',
                'sina.com.cn' => 'http://mail.sina.com.cn',
                'sina.com' => 'http://mail.sina.com.cn',
                'sina.cn' => 'http://mail.sina.com.cn',
                'vip.sina.com' => 'http://vip.sina.com',
                'yahoo.com.cn' => 'http://mail.cn.yahoo.com',
                'yahoo.cn' => 'http://mail.cn.yahoo.com',
                'yahoo.com' => 'http://mail.yahoo.com',
                'sohu.com' => 'http://mail.sohu.com',
                'chinaren.com' => 'http://mail.chinaren.com',
                'hotmail.com' => 'http://mail.hotmail.com',
                'msn.com' => 'http://mail.hotmail.com',
                'live.com' => 'http://mail.hotmail.com',
                'live.cn' => 'http://mail.hotmail.com',
                '21cn.com' => 'http://mail.21cn.com',
                '263.net' => 'http://mail.263.net',
                'sogou.com' => 'http://mail.sogou.cn',
                'hexun.com' => 'http://mail.hexun.com',
                'wo.com.cn' => 'http://mail.wo.com.cn',
                '189.cn' => 'http://mail.189.cn',
                '139.com' => 'http://mail.10086.cn'
            );
            foreach ($urlarr as $key => $value) {
                if (strpos($email, $key)) {
                    $url = $value;
                    break;
                } else {
                    $url = '';
                }
            }
        } else {
            $url = '';
        }
        return $url;
    }
 
    public static function log($logFile, $data) {
        error_log("[" . date("Y-m-d H:i:s") . "]$data\r\n", 3, $logFile);
    }
 
 
  
72、对查询结果集进行排序  @access public   @param array $list 查询结果    @param string $field 排序的字段名    @param array $sortby 排序类型     asc正向排序 desc逆向排序 nat自然排序   @return array
 
  
   public static function listSort($list, $field, $sortby = 'asc') {
        if (is_array($list)) {
            $refer = $resultSet = array();
            foreach ($list as $i => $data)
                $refer[$i] = &$data[$field];
            switch ($sortby) {
                case 'asc': // 正向排序
                    asort($refer);
                    break;
                case 'desc':// 逆向排序
                    arsort($refer);
                    break;
                case 'nat': // 自然排序
                    natcasesort($refer);
                    break;
            }
            foreach ($refer as $key => $val)
                $resultSet[] = &$list[$key];
            return $resultSet;
        }
        return false;
    }
 
 
  
73、安全过滤数据       @param string    $str        需要处理的字符        @param string    $type       返回的字符类型，支持，string,int,float,datetime,bool,array,html      @param maxid        $default    当出现错误或无数据时默认返回值         @return         mixed        当出现错误或无数据时默认返回值
 
  
 public static function getStr($str, $type = 'string', $default = '') {
        if (!is_array($str)) {
            $str = trim($str);
        }
 
        switch ($type) {
            case 'string': //字符处理
                $_str = strip_tags(SUtil::deHttpFilter($str));
                $_str = htmlspecialchars($_str, ENT_QUOTES);
                break;
            case 'int': //获取整形数据
 
                $_str = is_numeric($str) ? intval($str) : $default | 0;
                break;
            case 'float': //获浮点形数据
                $_str = is_numeric($str) ? floatval($str) : $default | 0;
                break;
            case 'datetime':
                $_str = SUtil::isDate($str) ? $str : $default;
                break;
            case 'bool':
                $_str = strtolower($str) == 'true' ? TRUE : (strtolower($str) == 'false' ? FALSE : $default);
                break;
            case 'array':
                if (is_array($str)) {
                    $_str = $str;
                } else {
                    $_str = preg_split('/[,]/i', $str);
                    foreach ($_str as $key => $value) {
                        if (trim($value) == "")
                            unset($_str[$key]);
                    }
                }
                break;
            case 'html': //获取HTML，防止XSS攻击
                $_str = self::reMoveXss(SUtil::deHttpFilter($str));
                break;
 
            default: //默认当做字符处理
                $_str = SUtil::HttpFilter(strip_tags(SUtil::deHttpFilter($str)));
        }
        return $_str;
    }
 
  
74、验证是否是时间格式
 
  
 public static function isDate($sDate) {
        return preg_match("/^[0-9]{4}\-[0-9]{1,2}\-[0-9]{1,2}( [0-9]{1,2}:[0-9]{1,2}:[0-9]{1,2})?$/", $sDate);
    }
 
  
75、兼容php5.5的array_column函数    @param unknown_type $input     @param unknown_type $columnKey    @param unknown_type $indexKey
 
  
 public static function arrayColumn($input, $columnKey, $indexKey = null) {
        if (!function_exists('array_column')) {
            $columnKeyIsNumber = (is_numeric($columnKey)) ? true : false;
            $indexKeyIsNull = (is_null($indexKey)) ? true : false;
            $indexKeyIsNumber = (is_numeric($indexKey)) ? true : false;
            $result = array();
            foreach ((array) $input as $key => $row) {
                if ($columnKeyIsNumber) {
                    $tmp = array_slice($row, $columnKey, 1);
                    $tmp = (is_array($tmp) && !empty($tmp)) ? current($tmp) : null;
                } else {
                    $tmp = isset($row[$columnKey]) ? $row[$columnKey] : null;
                }
                if (!$indexKeyIsNull) {
                    if ($indexKeyIsNumber) {
                        $key = array_slice($row, $indexKey, 1);
                        $key = (is_array($key) && !empty($key)) ? current($key) : null;
                        $key = is_null($key) ? 0 : $key;
                    } else {
                        $key = isset($row[$indexKey]) ? $row[$indexKey] : 0;
                    }
                }
                $result[$key] = $tmp;
            }
            return $result;
        } else {
            return array_column($input, $columnKey, $indexKey);
        }
    }
 
 
  
76、加密函数，可用cp_decode()函数解密，$data：待加密的字符串或数组；$key：密钥；$expire 过期时间
 
  
 public static function cp_encode($data, $key = '', $expire = 0) {
        $string = serialize($data);
        $ckey_length = 4;
        $key = md5($key);
        $keya = md5(substr($key, 0, 16));
        $keyb = md5(substr($key, 16, 16));
        $keyc = substr(md5(microtime()), -$ckey_length);
 
        $cryptkey = $keya . md5($keya . $keyc);
        $key_length = strlen($cryptkey);
 
        $string = sprintf('%010d', $expire ? $expire + time() : 0) . substr(md5($string . $keyb), 0, 16) . $string;
        $string_length = strlen($string);
        $result = '';
        $box = range(0, 255);
 
        $rndkey = array();
        for ($i = 0; $i <= 255; $i++) {
            $rndkey[$i] = ord($cryptkey[$i % $key_length]);
        }
 
        for ($j = $i = 0; $i < 256; $i++) {
            $j = ($j + $box[$i] + $rndkey[$i]) % 256;
            $tmp = $box[$i];
            $box[$i] = $box[$j];
            $box[$j] = $tmp;
        }
 
        for ($a = $j = $i = 0; $i < $string_length; $i++) {
            $a = ($a + 1) % 256;
            $j = ($j + $box[$a]) % 256;
            $tmp = $box[$a];
            $box[$a] = $box[$j];
            $box[$j] = $tmp;
            $result .= chr(ord($string[$i]) ^ ($box[($box[$a] + $box[$j]) % 256]));
        }
        return $keyc . str_replace('=', '', base64_encode($result));
    }
 
 
  
77、cp_encode之后的解密函数，$string待解密的字符串，$key，密钥
