How to store graph data in a php variable?

Question

I am trying to get the number of likes of a particular page on my website and store it in an array. Stuck in middle, i figured out that i can get the number of likes along with other data by the following code:

/*$site="http://graph.facebook.com/?ids=http%3a%2f%2xxxxxxxx.com/abc.php";
$graph= file_get_contents($site);

the output is as follows:

{"http:\/\/xxxxxxxx.com\/abc.php":{"id":"http:\/\/xxxxxxxx.com\/abc.php","shares":75,"comments":3}}

is there a way i can just store the number of likes i.e. in this case 75 in a php array?

I tried explode(); but the problem is that the url that i would be using wont be of a constant length.

That data format is called JSON, so look up json_decode in the manual. Btw., if you would use the PHP SDK, it would do the necessary stuff for you automatically. — C3roe

@CBroe yea i guessed it was JSON but was just curious if this can be done using PHP by the same output results. Thanks anyways — Arihant

Why don't you use the PHP SDK? Its a lot easier and its more future-proof. — Relaxing In Cyprus

@FacebookAnswers, what if i have multiple like buttons on the same page and if they arent the like buttons for facebook pages but my website's particular pages — Arihant

This is a json string decode it, use json_decode you will get the output as array. ref : http://php.net/manual/en/function.json-decode.php

$array  = json_deocde($json_string, true);

echo "<pre>";
print_r($array);

Did get the values in array but a stupid question, it says 'Array (....[shares]=>75.....)' How do i get this to a variable? What index should i give to the array?

$var = $array['shares'];

I tried that , it didn't work. It gave a following Notice: Undefined index: shares in C:\xampp\htdocs\graphapi.php on line 19
