$json = stream_get_contents($handle);
fclose($handle);
echo $json;
$obj = json_decode($json);
print $obj->{'id'};
?>

İşte JSON: {"data":[{"name":"Sinan \u00d6zcan","id":"610914868"}]}

Bu JSON echos ama id baskı yapamaz oldu.

Ayrıca ben denedim:

<?php
$obj = json_decode($json);
$obj = $obj->{'data'};
print $obj->{'id'};
?>
