Question

I want to create Unique ID for my site users in this format

pubID-john_34032

So I want to do this using the email string.

I have this pseudo code (but I want it faster and more logical if that makes sense)

How do I write my Pseudo code as PHP?

<?php
$var e(mysqlescape(get(emailform));
$var r(rand(3,34);
$var ex=(pubID-);
$var e=(replace(@/.); //users may enter [e-mail] so replace the at and .
$var e(first4strTo(e)); // get first four letters, example 1sit 
$var e(e)+r(); // e is now 1site-1547
$var printStr e+ex //join the 1site-1547 with pubID- and done
?>

Use str_replace() to remove the @ and . characters then use uniqid() to generate a unique identifier. Finally, concatenate them all together.

$email = '[e-mail]';
$str = 'pubID-' . str_replace(array('@', '.'), '', $email) . '_' . uniqid();
echo $str;
