URL Shortener using Auto-Increment field.

Published by Matheus (X-warrior) Bratfisch on October 19, 2009

Good Night,

This is a new version of URL-Shortener that don’t create random IDs to websites, it uses the auto-increment field and replace it to other base.

It was necessary to create two new methods
[code lang=”php”]
function convertDecimalTo($decimal,$newBase,$str,$letters) {
if ($decimal >= $newBase) {
$x = $decimal % $newBase;
$y = $decimal / $newBase;
$str = $letters{$x} . $str;
if ($y < $newBase) { $str = $letters{$y} . $str; } return convertDecimalTo($y,$newBase,$str,$letters); } else { if (strlen($str) == 0) { $str = $letters{$decimal} . $str; } return $str; } } function convertBaseToDecimal($value,$newBase,$letters) { $sum = 0; $len = strlen($value); $end = $len-1; for ($x=$end;$x>=0;$x–) {
$sum = $sum + strpos($letters,$value{$x}) * pow($newBase,($end – $x));
}
return $sum;
}
[/code]
