What are some potential issues when trying to execute a .bat file using PHP on a Windows server?

One potential issue when trying to execute a .bat file using PHP on a Windows server is that the server may not have the necessary permissions to run the file. To solve this, you can use the `exec()` function in PHP to run the .bat file with the appropriate permissions.

$output = shell_exec('C:\\path\\to\\your\\file.bat');
echo $output;
