How can the "malformed header from script" error be resolved when switching to a new PHP version?

The "malformed header from script" error can be resolved by ensuring that the header function is called before any output is sent to the browser. This error occurs when headers are sent after content, which can cause issues with the script execution. To fix this, make sure to call the header function at the beginning of the script, before any HTML or text output.

<?php
// Ensure headers are sent before any output
header("Content-Type: text/html");
// Rest of the PHP code goes here
?>
