Question

I would like to change number (ie. 19455) into something shorter using numbers and digits (ie. w3b) so for example number 19455 is replaced by w3b. I would like to be able to get back that number when I enter w3b. Is there a ready function that I could use or do I have to build it by myself?

Answer 1

Use base_convert php function:

Example:

$myNumInDecimal = "1234567787";
$myNumInBase36 = base_convert($myNumInDecimal, 10, 36);

this will give you:

BUT notice that both to and from bases should be between 2..36.
