这里实现的PHP导入导出excel功能用到的是开源PHPExcel,执行下面的操作之前请先下载该类库文件,官方网站:http://www.codeplex.com/PHPExcel,官网案例代码很多,导出pdf什么的都有,这里主要介绍PHP导入导出excel的功能,导出excel文件是office2007格式,同时兼容2003。 php导入excel 导入的excel文件的数据格式,截图如下: 下面是将该excel文件的数据导入到数据库的具体代码: 代码如下: <?php require_once 'Classes/PHPExcel.php'; require_once 'Classes/PHPExcel/IOFactory.php'; require_once 'Classes/PHPExcel/Reader/Excel5.php'; $objReader=PHPExcel_IOFactory::createReader('Excel5');//use excel2007 for 2007 format $objPHPExcel=$objReader->load($file_url);//$file_url即Excel文件的路径 $sheet=$objPHPExcel->getSheet(0);//获取第一个工作表 $highestRow=$sheet->getHighestRow();//取得总行数 $highestColumn=$sheet->getHighestColumn(); //取得总列数 //循环读取excel文件,读取一条,插入一条 for($j=2;$j<=$highestRow;$j++){//从第一行开始读取数据  $str='';  for($k='A';$k<=$highestColumn;$k++){            //从A列读取数据  //这种方法简单,但有不妥,以'\\'合并为数组,再分割\\为字段值插入到数据库,实测在excel中,如果某单元格的值包含了\\导入的数据会为空          $str.=$objPHPExcel->getActiveSheet()->getCell("$k$j")->getValue().'\\';//读取单元格  }  //explode:函数把字符串分割为数组。  $strs=explode("\\",$str);  $sql="INSERT INTO `".TB_PREFIX."business`(`username`,`password`,`company`,`prov`,`address`,`btime`,`phone`,`email`,`name`) VALUES (  '{$strs[0]}',  '{$strs[1]}',  '{$strs[2]}',  '{$strs[3]}',  '{$strs[4]}',  '{$strs[5]}',  '{$strs[6]}',  '{$strs[7]}',  '{$strs[8]}')";  $db->query($sql);//这里执行的是插入数据库操作 } unlink($file_url); //删除excel文件 ?> php导出excel 下面直接放出本人总结的使用PHP导出Excel的部分调用代码。 复制代码 代码如下: <?php error_reporting(E_ALL); date_default_timezone_set('Asia/Shanghai'); require_once './Classes/PHPExcel.php'; $data=array(  0=>array(   'id'=>1001,   'username'=>'张飞',   'password'=>'123456',   'address'=>'三国时高老庄250巷101室'  ),  1=>array(   'id'=>1002,   'username'=>'关羽',   'password'=>'123456',   'address'=>'三国时花果山'  ),  2=>array(   'id'=>1003,   'username'=>'曹操',   'password'=>'123456',   'address'=>'延安西路2055弄3号'  ),  3=>array(   'id'=>1004,   'username'=>'刘备',   'password'=>'654321',   'address'=>'愚园路188号3309室'  ) );
