extracting single digit.

[showman13]

Could someone tell me how to extract the right most single digit from a number without knowing the length of the number?

123 I need the 3

386485 I need the 5

etc...

Seems it should be simple, but been searching for over an hour and can't find the resolution...

Thanks in advance

Try substr(): http://www.php.net/manual/en/function.substr.php

$a = 1234;
echo substr($a,-1,1); # outputs 4
