Converting between different number bases

Hi

I have a number base (in base 62) which is represented like this:

$base = "0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ";

PHP:

Can anyone help me with a function that converts from decimal (base 10) to this new base please ?

Thanks,
Brew

 

<?php
$number = "0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ";
$beginbase = 62;
$newbase = 10;

echo base_convert($number, $beginbase , $newbase);
?>

Code (markup):

 

According to www.php.net, base_convert only works with bases upto 36
