How can proper error reporting and debugging techniques be used to troubleshoot PHP string manipulation errors?

When troubleshooting PHP string manipulation errors, it is important to use proper error reporting techniques such as enabling error reporting and displaying errors on the screen. Additionally, utilizing debugging techniques like var_dump() or print_r() can help identify the source of the error in the string manipulation code. By carefully examining the output and error messages, you can pinpoint the issue and make necessary corrections. 

<?php
// Enable error reporting
error_reporting(E_ALL);
ini_set('display_errors', 1);

// String manipulation code
