What are some common pitfalls when trying to execute a file in a specific directory using PHP on a Linux system?

One common pitfall when trying to execute a file in a specific directory using PHP on a Linux system is not providing the full path to the file. To solve this issue, you can use the `chdir()` function to change the current working directory to the desired directory before executing the file. 

<?php
// Set the desired directory path
$directory = '/path/to/desired/directory';

// Change the current working directory to the desired directory
chdir($directory);

// Execute the file in the desired directory
exec('php file_to_execute.php');
?>
