Generate UUID in PHP

Answer:

To generate UUID in PHP, you can try the script below:

<?php

function uuid($prefix = '') {
    $chars = md5(uniqid(mt_rand(), true));
    $uuid  = substr($chars,0,8) . '-';
    $uuid .= substr($chars,8,4) . '-';
    $uuid .= substr($chars,12,4) . '-';
    $uuid .= substr($chars,16,4) . '-';
    $uuid .= substr($chars,20,12);
    return $prefix . $uuid;
}

echo uuid();

It shows something like the following when executed:
