скрипт опреления PR

если делаете порядка 15 запросов за один заход, то получите бан от гугля на пару часов. может быть поэтому ваш скрипт не работает ?:)

Тоже самое , pr что то тупит .

Бан исключается , у меня , например , динамический ИП .

SeoQuake показывает PR только на процентах 30 сайтах ..

У меня все прекрасно работает, делаю 3-4 запроса в минуту с одного IP

вот скрипт:

<?php

/**

 * Google Page rank data grabber.

 *  PHP standard fopen/fread or other)

 * 

 * @version 1.1

 * @author exstabler // PHP version

 * @author snoopy    // JS version

 * 

 * @changelog:

 *  - 2007-01-18:

 *  1. [exstabler] Deprecated method intToHex deleted.

 *  2. [exstabler] Method toHex8 corrected.
