How can header data be managed effectively when rendering modules in a PHP template?

When rendering modules in a PHP template, it is important to manage header data effectively to ensure that the correct headers are sent before any content. One way to achieve this is by using output buffering to capture all output before sending it to the browser. This allows you to set headers at any point in your code, even after content has been echoed. 

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

// Your PHP code to render modules goes here

// Set headers
header('Content-Type: text/html');

// Get the buffered content
$output = ob_get_clean();

// Send headers and content
echo $output;
