Why Can\'t I Execute Bash Scripts From PHP?

Executing Bash Commands from PHP

Attempting to run a bash script from PHP using commands like shell_exec, exec, and system can sometimes fail. One possible reason for this is an issue with the current working directory.

To resolve this problem, you can explicitly change the working directory before executing the script using the chdir function. Here's an example:

<code class="php">$old_path = getcwd(); // Store the current working directory
chdir('/my/path/'); // Change to the correct directory
$output = shell_exec('./script.sh var1 var2'); // Execute the script
chdir($old_path); // Revert to the previous working directory</code>

By specifying the correct directory, you ensure that the bash script is executed in the intended environment. This should resolve the issue you were facing when executing the script from a PHP file.
