What are the best practices for transitioning a shell script to PHP?

When transitioning a shell script to PHP, it's important to consider the differences in syntax and functionality between the two languages. One of the best practices is to break down the shell script into smaller functions and then rewrite them in PHP. Additionally, make sure to properly handle input/output operations, error handling, and any system commands that were used in the shell script. 

<?php
// Example shell script command: echo "Hello, World!"
$output = shell_exec('echo "Hello, World!"');
echo $output;
?>
