A few questions about php preg_match_all

Question

How can I retrieve the result from the $avatar array?
This is what I tried:
I want to get the following(url):
code:

<div id="fotoprofilo"><img src="http://images.instagram.com/profiles/profile_19347213_75sq_0000.jpg"></div>

And php:

$s2 = file_get_contents("http://followgram.me/user");
    $avatar = "";
     preg_match_all('/fotoprofilo\s*"><img src=".*\b">/', $s2, $avatar);
    print_r($avatar[0]);

1) How is the result working?
2) Will it find it? (Because I can't seem to see the value)

Thanks in advance.

Also, your server must be configured to allow file_get_contents to retrieve files over http://, per default it only works with local files — knittl, Mar 04 '12 at 15:21
#knittl It actually works for me :) (the http), I am checking the don't use... Plus, how does the result work?! — funerr, Mar 04 '12 at 15:24
I agree with knittl - Use one of the **perfectly good XML/HTML parsers** out there — Kian, Mar 04 '12 at 15:29

Use an array and brackets for subexpressions:

$s2 = file_get_contents("http://followgram.me/user");
$avatar = array();
preg_match_all('/fotoprofilo\s*"><img src="(.*)">/', $s2, $avatar);
print_r($avatar);

$avatar[1] should contain your URL.

To test regex and preg_match_all you can use http://reghex.mgvmedia.com/. Choose "PHP" as language and check option "global search". Works fine :)
