Script in PHP pentru aflare PR

[Marius Cristian]

Cel mai bun de pana acum. Daca nu merge link-ul direct se rezolva adaugand un "/" la sfarsit. Insa nu merge, bienintels, daca e un link care are o extensie cu sau fara parametrii (.html, .php?param1=12 samd). Am mai obtinut cateva rateuri. Ce e drept, foarte putine.

Am si eu unul in calculator cu care m-am jucat mai demult. La mine functioneaza, acum vezi daca e ce iti trebuie tie:

<?php

if (isset($_POST['urls']))
{
$tempurls=$_POST['urls'];
$pieces = explode("\n", $tempurls);
$size=sizeof($pieces);
