URL shortner using Bitly - PHP

For creating a shorten url you need to create an account in the following link:

http://dev.bitly.com/my_apps.html

Now go to 

https://bitly.com/a/oauth_apps 

Here you need to create a accesstoken if you are creating for the first time it prompts for the password.

Then you get a alpha numeric value as accesstoken section.


Now use the following Code:

    $url = "https://api-ssl.bitly.com/v3/shorten";
    $strPost = "longUrl=http%3A%2F%2Fgoogle.com%2F&   access_token=YOUR ACCESSTOKEN";
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    // curl_setopt($ch, CURLOPT_PROXY, $proxy);
    curl_setopt($ch, CURLOPT_HEADER, 1);
    curl_setopt($ch, CURLOPT_HTTPGET,1);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
    curl_setopt($ch, CURLOPT_HTTPHEADER, Array("Content-Type: application/json"));
    curl_setopt($ch, CURLOPT_HEADER, FALSE);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $strPost); // add POST fields
    curl_setopt($ch, CURLOPT_POST, 1);
    $result = curl_exec($ch);
    var_dump($result);
    curl_close($ch);

The output of this file will return a json string

{
    "status_code" : 200,
    "status_txt" : "OK",
    "data" : {
        "long_url" : "http:\/\/google.com\/",
        "url" : "http:\/\/bit.ly\/14UO8lv",
        "hash" : "14UO8lv",
        "global_hash" : "900913",
        "new_hash" : 1
    }
}


NOTE
The bitly code is to be used for personal accounts cannot be used for Enterprise use if you want to use it for Enterprise you need to request them for the details but this code even works for that Code too.

Curl Using PHP in a Gist

cURL: It is  a client that deals with URL so its named as cURL so as to say that it deals with URL only 

It is used to make client communicate with the server using command line 
arguments using cURL syntax

Its main use is to provide security to the URL's sent through the browser to the server
 
 The main commands in cURL  which i found is important are


1. curl_init() - with which the main curl operation starts

2.curl_setop($charecter,options,value) - 


                    $charecter = curl handle returned by curl_initi()

           options = curl provides various options with general syntax 

curlOPT_XXX 

                         other options are found in - PHP website

          value = value of the url

3. curl_exec() - which is used to execute a $charecter in which the information has be moved 

4.curl_close() - this is used to close the curl connection
