URL Shortener using Auto-Increment field.
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
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 $sum;
}
if ($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;
}
