How can you ensure that PHP has the necessary permissions to execute external commands?

To ensure that PHP has the necessary permissions to execute external commands, you can use the `sudo` command in your PHP script. This allows PHP to run the external command with elevated permissions. However, it's important to be cautious when using `sudo` as it can pose security risks if not implemented properly. 

<?php
$command = 'sudo your_external_command_here';
$output = shell_exec($command);
echo $output;
?>
