<?
include("LIB_parse.php");
include("LIB_http.php");


$var=$_POST['SearchText'];

$web_page = http_get($target="http://www.google.com/search?q=$var", $referer="");

$title_excl = return_between($web_page['FILE'], "<title>", "</title>", EXCL);



$result1_excl = return_between($web_page['FILE'], "<h3 class="r">", "</h3 class="r">", EXCL);

$resulttext_excl = return_between($web_page['FILE'], "<span class="st">", "</span class="st">", EXCL);



echo $title_excl;
