Your

$json = file_get_contents('http://onleague.stormrise.pt:8031/OnLeagueRest/resources/onleague/Social/WallEntries?id_user=a7664093-502e-4d2b-bf30-25a2b26d6021&count=3');

returns not a valid json string that can be converted into array by json_decode. If you look inside, you will find substrings like:

"dateAdded":2011-05-21T00:00:00+01:00

2011-05-21T00:00:00+01:00 here should be enclosed in ” to give you a valid json string that may be parsed by json_decode. So, your $data is now NULL (that’s what json_decode returned)
