从 PHP 运行 Bash 命令 [英] Run Bash Command from PHP

问题描述

我有一个 bash 脚本，我通过命令行运行它:

I have a bash script, that I run like this via the command line:

./script.sh var1 var2

我试图在调用某个 php 文件后执行上述命令.

I am trying to execute the above command, after I call a certain php file.

我现在拥有的是:

$output = shell_exec("./script.sh var1 var2");
echo "<pre>$output</pre>";

但它不起作用.我也使用 exec 和 system 尝试过，但脚本从未执行过.

But it doesn´t work. I tried it using exec and system too, but the script never got executed.

但是，当我尝试运行 shell_exec("ls"); 时它确实有效，并且 $output 是所有文件的列表.

However when I try to run shell_exec("ls"); it does work and $output is a list of all files.

我不确定这是因为我使用的 VPS 的限制还是问题出在其他地方?

I am not sure whether this is because of a limitation of the VPS I am using or if the problem is somewhere else?

推荐答案

您可能需要 chdir 到正确的目录.这样你就可以在调用 shell 命令之前确保你的脚本在"哪个目录.

You probably need to chdir to the correct directory before calling the script. This way you can ensure what directory your script is "in" before calling the shell command.

$old_path = getcwd();
chdir('/my/path/');
$output = shell_exec('./script.sh var1 var2');
chdir($old_path);
