How can header information already sent errors be resolved in PHP scripts, especially when dealing with form submissions?

When dealing with form submissions in PHP scripts, header information already sent errors can be resolved by ensuring that no output is sent to the browser before calling functions like header(). To solve this issue, you can use output buffering to capture any output before sending headers. This way, you can manipulate headers without encountering errors.

php

<?php
ob_start(); // Start output buffering

// Your PHP code for form submission here

ob_end_flush(); // Send the output buffer
