Integer To Alphanumeric Character
A function that converts an integer between 0 and 61 into an alphanumberic character. Ranges from 0-9, A-Z, a-z. Very handy for generating random strings and stuff like that.
function map_char($num) {
$int = $num; $int+=48;
($int > 57) ? $int += 7 : null;
($int > 90) ? $int += 6 : null;
return chr($int);
}
