* Local variables: 
* tab-width: 4 
* c-basic-offset: 4 
* c-hanging-comment-ender-p: nil 
* End: 
*/ 
?>

2、调用方法
<?php 
$data = new ReadexcelSystem(); 
$data->setOutputEncoding('utf-8'); 
$data->read($location); 
print_r($data->sheets[0]['cells'] ); 
?> 
$data->sheets[0]['cells']

就是我们要获取的excle文件里的数据
