shell_exec(),exec() on php is not working

Question

我通过关闭值禁用了safe_mode，并尝试在1and1专用服务器上使用shell_exec（），exec（）这两个功能都无法正常工作，甚至无法在另一台服务器上工作。

Answer 1

Those (and any other) functions can be disabled in the php.ini. I do this on my servers often. Perhaps you should ask them if those functions are enabled?
