Returning JSON from a PHP Script

Question

I want to return JSON from a PHP script.

Do I just echo the result? Do I have to set the Content-Type header?

Answer 1

You can use this little PHP library. It sends the headers and give you an object to use it easily.

It looks like :

test = 'OK';
$arraytest = array('1','2','3');
$jsonOnly = '{"Hello" : "darling"}';

// Add some content
$Json->add('width', '565px');
$Json->add('You are logged IN');
$Json->add('An_Object', $object);
$Json->add("An_Array",$arraytest);
$Json->add("A_Json",$jsonOnly);

// Finally, send the JSON.

$Json->send();
?>
