require_once 'Classes/PHPExcel.php';
$import=new Excel(); 
$import->initialized(dirname(__FILE__) . '/test.xlsx'); 
header("Content-type: text/html; charset=utf-8"); 
echo '<pre>', print_r($import->fetch()), '</pre>';



?>
其中的$import->initialized(dirname(__FILE__) . '/test.xlsx'); test.xlsx修改为自己的execl路径
require_once 'Classes/PHPExcel.php';修改为你自己PHPExcel.php所在的路径
