在本地使用require_once('/ta.php');可以运行。
但是放到服务器上，就不行了。说我多了一个斜杠。但是这个斜杠不能去掉。怎么解决啊。是不是PHP版本不一样的问题。

回复讨论(解决方案)

为什么斜杠不能去掉。。。

你的服务器是liunx的还是windows的？

使用 / 表示使用绝对路径 如果要使用相对路径 请去掉或者使用./     ./表示当前目录 比如这样 

require_once('System/Defined.php');require_once('./System/Defined.php');
Copy after login


另外 不同系统的目录分隔符是不一样的 windows是 \ linux 是 ／ 要兼容的话 php有内置常量 DIRECTORY_SEPARATOR 可以代替
所以上面代码可以变成: 
require_once('System'.DIRECTORY.'Defined.php');
Copy after login

require_once $_SERVER['DOCUMENT_ROOT'].'/ta.php';
