PHPExcel导入文件就报错，求解~

报错内容如下：

Fatal error: Uncaught exception 'Exception' with message 'Multibyte function overloading in PHP must be disabled for string functions (2).' in F:\xampp\htdocs\MyTest\PHPExcel\Classes\PHPExcel\Autoloader.php:34 Stack trace: #0 F:\xampp\htdocs\MyTest\PHPExcel\Classes\PHPExcel.php(32): require() #1 F:\xampp\htdocs\MyTest\PHPExcel\ee.php(3): require_once('F:\xampp\htdocs...') #2 {main} thrown in F:\xampp\htdocs\MyTest\PHPExcel\Classes\PHPExcel\Autoloader.php on line 34

回复讨论(解决方案)

我不会猜谜语

看demo就行了

在你运行系统的PHP的php.ini 文件中像下面一样注释掉这行试试，记得重启php  
;mbstring.func_overload = 2

还是看PHPExcel的demo就ok了！
