1.2.1362. Use json_decode() Options¶
json_decode() returns objects by default, unless the second argument is set to TRUE or JSON_OBJECT_AS_ARRAY. Then, it returns arrays.
Avoid casting the returned value from json_decode(), and use the second argument to directly set the correct type.
Note that all objects will be turned into arrays, recursively. If you’re expecting an array of objects, don’t use the JSON_OBJECT_AS_ARRAY constant, and change your JSON code.
Note that JSON_OBJECT_AS_ARRAY is the only constant : there is no defined constant to explicitly ask for an object as returned value.
<?php
$json = '{"a":"b"}';
// Good syntax
$array = json_decode($json, JSON_OBJECT_AS_ARRAY);
// GoToo much work
$array = (array) json_decode($json);
?>
