What steps should be taken to troubleshoot and resolve issues with a PHP script that is not functioning as intended?

Issue: If a PHP script is not functioning as intended, the first step is to check for syntax errors, missing semicolons, or incorrect variable names. Next, ensure that all required files are included correctly and that the server has the necessary permissions to run the script. Finally, use debugging tools like error logs or print statements to identify any logical errors in the code.

<?php
// Check for syntax errors and missing semicolons
// Ensure all required files are included correctly
// Verify server permissions are set up properly

// Example debugging statement
echo "Script is running...";

// More code here
?>
