Run Bash Command from PHP

bash, exec, php

Solution

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);

Problem

I have a bash script, that I run like this via the command line: ``` ./script.sh var1 var2 ``` I am trying to execute the above command, after I call a certain php file. What I have right now is: ``` $output = shell_exec("./script.sh var1 var2"); echo "<pre>$output</pre>"; ``` But it doesn´t work. I tried it using `exec` and `system` too, but the script never got executed. However when I try to run `shell_exec("ls");` it does work and `$output` is a list of all files. I am not sure whether this is because of a limitation of the VPS I am using or if the problem is somewhere else?
