php开发中肯定会遇到将excel文件内容导入到数据库的需要，php-excel-reader是一个读取excel的类，可以很轻松的使用它读取excel文件非常方便。

php-excel-reader下载地址： http://www.jb51.net/codes/67223.html

我下载的是php-excel-reader-2.21版本，使用的时候还遇到几个小问题，后面再细说，先奉上php实例：

我使用的excel如下图：

php代码如下：

 
<?php 
/*by www.phpddt.com*/ 
header("Content-Type:text/html;charset=utf-8"); 
require_once 'excel_reader2.php'; 
//创建对象 
$data = new Spreadsheet_Excel_Reader(); 
//设置文本输出编码 
$data->setOutputEncoding('UTF-8'); 
//读取Excel文件 
$data->read("example.xls"); 
//$data->sheets[0]['numRows']为Excel行数 
for ($i = 1; $i <= $data->sheets[0]['numRows']; $i++) { 
//$data->sheets[0]['numCols']为Excel列数 
for ($j = 1; $j <= $data->sheets[0]['numCols']; $j++) { 
//显示每个单元格内容 
echo $data->sheets[0]['cells'][$i][$j].' '; 
} 
echo '<br>'; 
} 
?> 

读取结果截图如下：

再来说说这个类的小问题：

(1)出现Deprecated: Function split() is deprecated in 。。。错误

解决：将excel_reader2.php源码中split改为explode,详情点击php中explode与split的区别介绍

(2)出现Deprecated: Assigning the return value of new by reference is deprecated in错误

解决：将excel_reader2.php源码中$this->_ole =& new OLERead()中 &去掉，因为php5.3中废除了=& 符号直接用=引用

(3)乱码问题解决：

构造函数是function Spreadsheet_Excel_Reader($file='',$store_extended_info=true,$outputEncoding='')，它默认的编码是utf-8,如果不指定，可能会出现乱码问题，可通过$data->setOutputEncoding('GBK');指定，还有如果你使用dump()函数，dump()函数将excel内容一html格式输出,使用htmlentities将字符转化为html的,它默认使用ISO8559-1编码的，所以你要将 excel_reader2.php源码中 htmlentities($val)函数改为htmlentities($val,ENT_COMPAT,"GB2312");才行。

最后来说说，php-excel-reader操作excel中的两个重要的方法：

1.dump(),它可以将excel内容以html格式输出：

echo $data->dump(true,true);

2.将excel数据存入数组中，使用$data->sheets，打印下如下：
