推荐答案

有两个原因：

1. 的启动命令不执行PHP脚本的用户的路径。


2. 执行PHP脚本的用户不具有执行访问权的启动命令。

1. The start command is not in the path for the user executing the PHP script.
2. The user executing the PHP script does not have access right to execute the start command.

有关第一个，你可以给的完整路径启动在你的脚本。

For the first one, you can give the full path to start in your script.

对于第二部分，则需要与服务器管理员联系，要求为正常运行PHP脚本的用户执行权限。

For the second part, you need to contact the server administrator to request execute permissions for the user that normally runs PHP scripts.

如果您从浏览器中运行脚本，用户通常是运行您的Web服务器相同的过程（虽然有些服务器的其他用户的）。请与您的服务器管理员或主机。

If you are running the script from a browser, the user is usually the same process that is running your webserver (although on some servers its a different user). Check with your server admin or host.
