用php生成一个excel文件

1.我们用php来生成一个excel文档来讲述其原理：

excel2007里面的文档目录组成部分为：

2.我们使用ZipArchive()方法来生成一个简易的excel文件。

使用方法：

3.代码如下：

<?php
header("content-type:text/html;charset=utf-8");
//生成一个2007版本的excel文件
//1.实例化一个压缩文档对象
$ex= new ZipArchive();
//2.打开一个excel文件(2007版本)
$ex->open(&#39;./01.xlsx&#39;,ZIPARCHIVE::CREATE);
//3.创建excel文档的各个组成文件（文件目录、xml文件）
$ex->addFromString(&#39;[Content_Types].xml&#39;,"<?xml version=&#39;1.0&#39; charset=&#39;utf-8&#39; ?>");
$ex->addFromString(&#39;_rels/.rels&#39;,"<?xml version=&#39;1.0&#39; charset=&#39;utf-8&#39; ?>");
$ex->addFromString(&#39;docProps/app.xml&#39;,"<?xml version=&#39;1.0&#39; charset=&#39;utf-8&#39; ?>");
$ex->addFromString(&#39;docProps/core.xml&#39;,"<?xml version=&#39;1.0&#39; charset=&#39;utf-8&#39; ?>");
$ex->addFromString(&#39;docProps/custom.xml&#39;,"<?xml version=&#39;1.0&#39; charset=&#39;utf-8&#39; ?>");
$ex->addFromString(&#39;xl/_rels/workbork.xml.rels&#39;,"<?xml version=&#39;1.0&#39; charset=&#39;utf-8&#39; ?>");
$ex->addFromString(&#39;xl/theme/theme1.xml&#39;,"<?xml version=&#39;1.0&#39; charset=&#39;utf-8&#39; ?>");
$ex->addFromString(&#39;xl/theme/worksheets/sheet1.xml&#39;,"<?xml version=&#39;1.0&#39; charset=&#39;utf-8&#39; ?>");
$ex->addFromString(&#39;xl/theme/worksheets/sheet2.xml&#39;,"<?xml version=&#39;1.0&#39; charset=&#39;utf-8&#39; ?>");
$ex->addFromString(&#39;xl/theme/worksheets/sheet3.xml&#39;,"<?xml version=&#39;1.0&#39; charset=&#39;utf-8&#39; ?>");
$ex->addFromString(&#39;xl/styles.xml&#39;,"<?xml version=&#39;1.0&#39; charset=&#39;utf-8&#39; ?>");
$ex->addFromString(&#39;xl/workbook.xml&#39;,"<?xml version=&#39;1.0&#39; charset=&#39;utf-8&#39; ?>");
?>

执行php后会生成一个excel2007文件，把此文件改名压缩后就可以看到生成的文件，但此版本的excel文件并不完整，不能使用，要使用还需要借助excel包来完成大量的数据写入功能。此举只是完成ecxcel文件生成的理解。
