How can data be efficiently passed between PHP scripts to generate images without interfering with header settings?

When passing data between PHP scripts to generate images without interfering with header settings, one efficient way is to use sessions or cookies to store the data temporarily. This ensures that the header settings remain intact while the data is being passed between scripts.

<?php
session_start();

// Store data in session variable
$_SESSION['image_data'] = $imageData;

// Redirect to image generation script
header('Location: generate_image.php');
exit;
?>
