Търсачка с подобни на Google резултати

Автор: SandPrince

Тъй като никой не ми даде решение на въпроса с исканата от мен търсачка седнах и си потърсих. за моя изненада намерих това което най много се доближава до това което исках. реших да ви го пусна като урок , за тези на които би им потрябвало.

Първо ето структурата на търсачката

Основна папка
config.php
index.php
google.php
xml-keith-devens.php
Подпапки към основната и съдържание
папка: img
-logo.gif
-search.gif
папка: inc
-content.php
-focus.js
-home.php
-style.css

Започваме урока
