What debugging techniques can be used to troubleshoot issues with variable passing and form submission in PHP scripts?

When troubleshooting issues with variable passing and form submission in PHP scripts, one common technique is to use the `var_dump()` function to inspect the values of variables being passed. This can help identify any unexpected values or data types that may be causing issues. Additionally, checking the `$_POST` and `$_GET` arrays to ensure that form data is being properly submitted and received can help pinpoint the source of the problem.
