What are the best practices for debugging PHP scripts to identify potential errors or compatibility issues with newer PHP versions?

When debugging PHP scripts to identify potential errors or compatibility issues with newer PHP versions, it is important to use error reporting functions such as error_reporting(E_ALL) and ini_set('display_errors', 1) to display any errors or warnings. Additionally, checking the PHP documentation for deprecated functions or features that may cause issues with newer versions can help in identifying potential problems. Utilizing tools like Xdebug for step-by-step debugging and profiling can also aid in pinpointing errors and compatibility issues. 

<?php
error_reporting(E_ALL);
ini_set('display_errors', 1);

// Your PHP script code here
?>
