本次实现PHP导出Excel文件使用的是PHP开源程序PHPExcel，部分关键代码分享给大家，具体内容如下

<div class="jb51code">
<pre class="brush:PHP;">
<?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','address'=>'三国时花果山'
),2=>array(
'id'=>1003,'username'=>'曹操','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'
)
);
$objPHPExcel=new PHPExcel();
$objPHPExcel->getProperties()->setCreator('//www.jb51.cc')
->setLastModifiedBy('//www.jb51.cc')
->setTitle('Office 2007 XLSX Document')
->setSubject('Office 2007 XLSX Document')
->setDescription('Document for Office 2007 XLSX,generated using PHP classes.')
->setKeywords('office 2007 openxml PHP')

           ->setCategory('Result file');

$objPHPExcel->setActiveSheetIndex(0)

  ->setCellValue('A1','ID')

  ->setCellValue('B1','<a href="https://www.jb51.cc/tag/yonghuming/" target="_blank" class="keywords">用户名</a>')

  ->setCellValue('C1','密码')

  ->setCellValue('D1','地址');

$i=2;

foreach($data as $k=>$v){

$objPHPExcel->setActiveSheetIndex(0)
->setCellValue('A'.$i,$v['id'])
->setCellValue('B'.$i,$v['username'])
->setCellValue('C'.$i,$v['password'])
->setCellValue('D'.$i,$v['address']);

$i++;

}
$objPHPExcel->getActiveSheet()->setTitle('三年级2班');

$objPHPExcel->setActiveSheetIndex(0);
$filename=urlencode('学生信息统计表').'_'.date('Y-m-dHis');
