Just watch this usecase: <?php // International phone number json_encode(array('phone_number' => '+33123456789'), JSON_NUMERIC_CHECK); ?> And then you get this JSON: {"phone_number":33123456789} Maybe it makes sense for PHP (as is_numeric('+33123456789') returns true), but really, casting it as an int?! So be careful when using JSON_NUMERIC_CHECK, it may mess up with your data! ... Notice that JSON_FORCE_OBJECT will convert all non-associative arrays to objects. This is not necessarily a good solution for empty arrays. If you want to convert only empty arrays to objects, simply convert them to empty object before use json_encode function. For example: <?php $foo=array( 'empty2object'=>(object)[], 'empty2array'=>[], ); echo json_encode($foo); // {"empty2object":{},"empty2array":[]} ?>
