How can PHP developers ensure that their scripts have the necessary permissions to execute system commands, especially when interacting with external hardware like in the Raspberry Pi example?

PHP developers can ensure that their scripts have the necessary permissions to execute system commands by using the `sudo` command in their PHP code. This allows the script to run with elevated privileges, granting it the necessary permissions to interact with external hardware like in the Raspberry Pi example. 

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