PHPExcel文件导入导出常用方法
1、PHP文件导入
上传文件
页面样式
HTML代码
PHP代码文件上传与导入
load($file_name,$encode='utf-8');//加载文件
$sheet = $objPHPExcel->getSheet(0);//取得sheet(0)表
$highestRow = $sheet->getHighestRow(); // 取得总行数
$highestColumn = $sheet->getHighestColumn(); // 取得总列数
$conn=mysql_connect("localhost","root","syxsyx");
mysql_select_db("test11",$conn);
mysql_query("set names gb2312");
for($i=3;$i<=$highestRow;$i++)
{
$data['login_pk']=$objPHPExcel->getActiveSheet()->getCell("A".$i)->getValue();
$data['login_uid'] = $objPHPExcel->getActiveSheet()->getCell("B".$i)->getValue();
$data['login_time'] = $objPHPExcel->getActiveSheet()->getCell("C".$i)->getValue();
$data['login_ip']= $objPHPExcel->getActiveSheet()->getCell("D".$i)->getValue();
$sql = "insert into cb_member_login_log (login_pk,login_uid,login_time,login_ip) values ('".$data['login_pk']."','".$data['login_uid']."','".$data['login_time']."','".$data['login_ip']."')";
mysql_query($sql);
}
}
?>
使用TP框架进行文件导入
index.html
页面样式
ExcalController.class.php
导入excel的方法
function impUser(){
if (!empty($_FILES)) {
$upload = new \Think\Upload();
$upload->maxSize = 3145728 ;// 设置附件上传大小
$upload->exts = array('xlsx','xls');// 设置附件上传类型
$upload->rootPath ='./Uploads/Excel/';
// 上传文件
$info = $upload->upload();
if(!$info) {// 上传错误提示错误信息
$this->error($upload->getError());
}else{// 上传成功 获取上传文件信息
$file_name=$upload->rootPath.$info["import"]['savepath'].$info["import"]["savename"];//地址等于更目录加上创建的子目录加上文件名
}
vendor("PHPExcel.PHPExcel");
//文件名为文件路径和文件名的拼接字符串
$objReader = \PHPExcel_IOFactory::createReader('Excel5');//创建读取实例
/*
* log()//方法参数
* $file_name excal文件的保存路径
*/
$objPHPExcel = $objReader->load($file_name,$encode='utf-8');//加载文件
$sheet = $objPHPExcel->getSheet(0);//取得sheet(0)表
$highestRow = $sheet->getHighestRow(); // 取得总行数
$highestColumn = $sheet->getHighestColumn(); // 取得总列数
for($i=3;$i<=$highestRow;$i++)
{
$data['login_pk']=$objPHPExcel->getActiveSheet()->getCell("A".$i)->getValue();

M('member_login_log')->add($data);
}
$this->success('导入成功!');
}else
{
$this->error("请选择上传的文件");
}
}
2、文件导出
使用TP框架进行文件导出
index.html

//$expTableData文件数据
$xlsTitle = iconv('utf-8', 'gb2312', $expTitle);//文件名称 将字符串从utf-8编码转为gb2312编码
$fileName = "用户登录信息";//设置文件名称
$cellNum = count($expCellName);//获取文件的列数
$dataNum = count($expTableData);//获取数据的条数
vendor("PHPExcel.PHPExcel");//导入PHPExcal类库
//不加\会提示notfound 原因为引入命名空间
$objPHPExcel = new \PHPExcel();//生成PHPExcel类实例

//处理惩罚中文输出题目
须要将字符串转化为UTF-8编码,才干正常输出,不然中文字符将输出为空白,如下处理惩罚:
$str = iconv(""gb2312"", ""utf-8"", $str);
或者你可以写一个函数专门处理惩罚中文字符串:
function convertUTF8($str)
{
if(emptyempty($str)) return """";
return iconv(""gb2312"", ""utf-8"", $str);
}
//从数据库输出数据处理惩罚体式格式
从数据库读取数据如:
$db = new Mysql($dbconfig);
$sql = "SELECT * FROM 表名";
$row = $db->GetAll($sql); // $row 为二维数组
$count = count($row);
for ($i = 2; $i <= $count+1; $i++) {
$objPHPExcel->getActiveSheet()->setCellValue(""A"" . $i, convertUTF8($row[$i-2][1]));
$objPHPExcel->getActiveSheet()->setCellValue(""B"" . $i, convertUTF8($row[$i-2][2]));
$objPHPExcel->getActiveSheet()->setCellValue(""C"" . $i, convertUTF8($row[$i-2][3]));
$objPHPExcel->getActiveSheet()->setCellValue(""D"" . $i, convertUTF8($row[$i-2][4]));
$objPHPExcel->getActiveSheet()->setCellValue(""E"" . $i, convertUTF8(date("Y-m-d", $row[$i-2][5])));
$objPHPExcel->getActiveSheet()->setCellValue(""F"" . $i, convertUTF8($row[$i-2][6]));
$objPHPExcel->getActiveSheet()->setCellValue(""G"" . $i, convertUTF8($row[$i-2][7]));
$objPHPExcel->getActiveSheet()->setCellValue(""H"" . $i, convertUTF8($row[$i-2][8]));
}
在默认sheet后,创建一个worksheet
echo date(""H:i:s"") . " Create new Worksheet object\n";
$objPHPExcel->createSheet();
$objWriter = PHPExcel_IOFactory::createWriter($objExcel, ""Excel5"");
$objWriter-save(""php://output"");
