PHP笔记

//检查表单是否已提交
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
        echo "post";
    }


//post接受数据
$name = $_POST['name'];

数据库

session

session_start();//session开始

$_SESSION['name'] = $name;//设置session的值

//判断session存储的name是否存在
if(!isset($_SESSION['name'])){
        exit();
    }

//退出登录用到
      $_SESSION = array();
    //清楚客户端sessionid
    if(isset($_COOKIE[session_name()]))
    {
      setCookie(session_name(),'',time()-3600,'/');
    }
    //彻底销毁session
    session_destroy();
    echo "";

数据库操作1

$sql = "SELECT * FROM `wd_module` where parent_module ='".$row["id"]."' order by id";
$req = mysql_query($sql);
while ($ro = mysql_fetch_array($req))
  {
    //
    echo "
            |-------  ".$ro['name']."
            ".$ro['url']."
            ".$ro['remark']."
            ".$ro['create_time']."
            ".empty($ro['modify_time']? $ro['create_time']:$ro['modify_time'])."
          ";
  }
