Web Browser in PHP

We can use PEAR (PHP Extension and Application Repository) for more real life application.
PEAR is a framework and distribution system for reusable PHP components.

D:\xampp\php\PEAR\Net\Curl.php

<?php

include_once("Net\Curl.php");
$c = new Net_Curl();
$c->Net_Curl([URL], $_SERVER['HTTP_USER_AGENT']);
echo $c->execute();

?>

This simple code spider the page as the other web browser do, even there is problems with Curl, Sockets etc.!
