How to parse the code?

Question

PHP

How to parse this code?

{"response":[{"id":55xxxxx,"first_name":"Сергей","last_name":"Сергеев","sex":2,"photo_max_orig":"url"}]}

How to extract everything separately?
Tried like this:

$user = json_decode($info, true);

$photo = $user['photo_max_orig'];

but didn't help.
Notice: Undefined index: photo_max_orig

Answer 1

Try $photo = $user->photo_max_orig
And in order to avoid such questions, you can see what's inside $user like this:
var_dump($user) or print_r($user) + it is desirable to wrap it in a tag for convenience - it will make the output more readable.

Answer 2

$user = json_decode($info, true);
$photo = $user->{'photo_max_orig'};

Answer 3

Print_r:

Array ( [response] => Array ( [0] => Array ( [id] => 55xxxx [first_name] => Сергей [last_name] => Сергеев [sex] => 2 [screen_name] => id55xxxx [bdate] => 16.3.1994 [photo_max_orig] => url ) ) )

Answer 4

Just in case, comrade @Rickon above meant the pre tag. Something like:

<pre><?=var_dump($user)?></pre>
<pre><?=print_r($user)?></pre>

Answer 5

Output all $user elements through foreach, then you will understand the structure of the vk api response
In general, for a photo, for example

$user = json_decode($info, true);
$photo = $user['response'][0]['photo_max_orig'];
