php读取excel的实例代码

之前我们介绍了php写excel文件的实现代码，今天我们介绍使用PHPExcel读取excel文件，读取出的文件包含标题栏等信息的方法。
注意：单元格第一行以1开始，第一列以0开始
代码：

<?php
/**
* php 读取excel文件
* edit by www.jb200.com
*/
require_once 'PHPExcel.php';  
require_once 'PHPExcel/IOFactory.php';  
  
class ExcelHelper{  
    public function importFileContacts($filename){  
        try {  
            //解决文件中文名问题  
            $filename = iconv("UTF-8","GB2312",$filename);  
            if (!file_exists($filename)) {  
                return false;  
            }  
            //chmod($filename, 0750);linux下改变文件权限  
            $filetype = $this->getFileType($filename);  
            //根据文件类型读取excel文件

                }
