How can the order of PHP code execution, particularly in relation to headers, affect the functionality of passing objects between files?

When passing objects between files in PHP, it is important to ensure that headers are not sent before the object is serialized or unserialized. Sending headers prematurely can cause errors or unexpected behavior when trying to pass objects between files. To solve this issue, make sure to serialize or unserialize the object before any headers are sent in the code execution flow. 

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

// Serialize the object before sending any headers
$serialized_object = serialize($object);

// Send headers after serializing the object
header('Content-Type: application/json');

// Output the serialized object
echo $serialized_object;

ob_end_flush(); // Flush the output buffer
?>
