The perfect answer for everything: Google it!Only ask after you've done that. If you don't try that first, you're never going to get anything done.

I just did this HTTP Wrapper. It uses cURL to make HTTP requests, which can be very handy to emulate human browsing behavior.

 

Also, some of you might find this very handy and it could help you understand something about PHP from the examples I'm going to to give.

 

Heres the Wrapper, you need to save this as HTTPWrapper.class.php in Notepad or any PHP editor you have.

You will find this very handy because you won't need to rewrite all that mumbojumbo every time you want to use sockets.

 

How to use:

 

In your PHP page (the one you're going to write down the script) you will have to include the HTTPWrapper.class.php file.

<?phpinclude 'HTTPWrapper.class.php';?>

After you include the class file, you can use all the functions in it without having to write them again.

 

I'd like to explain how to use it now by making a sample script that will visit Google and search for the word "Cheese".

 

First of all we start our PHP script in the Body of the webpage and we tell PHP that we are naming the variable $Wrapper as a new HTTPWrapper like this:

<?php$user='Google'; //If you don't need a username like in this example, just put anything.$pass='anything'; //same with the pass.$Wrapper = new HTTPWrapper($user, $pass);?>

Now we have our HTTPWrapper ready to use.

 

The first thing we want to do is "Get" to the Google Page.

<?php$user='Google'; //If you don't need a username like in this example, just put anything.$pass='anything'; //same with the pass.$Wrapper = new HTTPWrapper($user, $pass); $Wrapper->HttpGet('google.com;;  echo $Wrapper->responseBody;?>

The code above will visit Google and print the html code into your page, allowing you to view the result of the Wrapper. This is very handy for debugging.

Now you know how to use one of the vars.

 

Once we are there, we want to search the word "Cheese". To make this easier, you should Packet Sniff your communication with the site, that way you know if you're POSTING or GETTING to the Website and the order of the Post data or the normal url.

 

After verifying the search url, I came up with this:

<?php$user='Google'; //If you don't need a username like in this example, just put anything.$pass='anything'; //same with the pass.$SearchWord='Cheese'; //What you're searching for.$Wrapper = new HTTPWrapper($user, $pass); $Wrapper->HttpGet('google.com;; $Wrapper->HttpGet('www.google.com/q=&%2339; . $SearchWord);  echo $Wrapper->responseBody;?>

The example above should now go to Google and search for "Cheese", then print the whole page's HTML into your .PHP page, letting you view your result.

 

You can impovise plenty with this Wrapper, you just need to spend some time searching for other commands you can combine with this such as preg_match_all and plenty others.

 

You can print data tables to your web page with information organized in different ways. PHP is truly a great language to learn.

 

I hope this Wrapper is used for good. =]
