Generating Random Avatars with Multiavatar API in PHP

While browsing, the author discovered a website that can generate random avatars (www.atoolbox.net/Tool.php?Id=1013) and later identified the actual service at https://multiavatar.com/ with a unique MD5 hash in the URL.

Using the browser's developer tools, they observed that changing the MD5 part of the URL produces different avatar images, confirming the generation mechanism.

Based on this insight, a simple PHP helper function is provided, which computes the MD5 hash of an email address and returns the corresponding Multiavatar PNG URL.

if (!function_exists('make_avatar')) {
    function make_avatar($email)
    {
        $md5_email = md5($email);
        return "https://api.multiavatar.com/{$md5_email}.png";
    }
}

This function enables developers to easily obtain a random avatar for any user without external dependencies.
