How can mixing HTML with image data affect the setting of cookies in PHP?

Mixing HTML with image data can affect the setting of cookies in PHP because when an image is requested, the browser may interpret the response as an image rather than HTML. This can cause issues with setting cookies as the browser may not handle them correctly. To solve this issue, you can ensure that the PHP script setting the cookies is not mixed with image data, or you can use output buffering to capture the cookie-setting code before any image data is sent. 

<?php
ob_start();

// Set cookies here
setcookie("cookie_name", "cookie_value", time() + 3600, "/");

ob_end_flush();

// Output image data here
header('Content-Type: image/jpeg');
readfile('image.jpg');
?>
