本文介绍了php中使用excelreader读取excel文件的方法，php-excel-reader可以读取excel文件，这是一个不错的phpexcel类库。
php使用excelreader读取excel文件
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.jb200.com/down/135.html
本文使用的是php-excel-reader-2.21版本。
php实例：
excel如下图：
例子，php-excel-readerphp代码：
复制代码 代码示例:
<?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][$j].' ';
}
echo '<br>';
}
?>
读取结果截图如下：
这个类的小问题：
1，出现deprecated: function split() is deprecated in 。。。错误
解决：将excel_reader2.php源码中split改为explode,详情点击php中explode与split的区别介绍
2，出现deprecated: assigning the return value of new by reference is deprecated in错误
解决：将excel_reader2.php源码中$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。
有希望了解phpexcel类库的朋友，可以阅读下phpexcel中文帮助手册中的内容，具体的实例大家可以phpexcel快速开发指南中的相关例子。
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：
复制代码 代码示例:
echo $data->dump(true,true);
2，将excel数据存入数组中，使用$data->sheets，打印下如下：
复制代码 代码示例:
