![]() When the array is empty ( ), a JSON array would be created when it’s not empty ( ), an object would be emitted instead. This handles the case where a variable contains an associative array which might be empty. JSON_FORCE_OBJECT – Convert PHP numerical arrays to JSON objects instead of arrays.Many more flags are supported when encoding data. Take care around the order though – in a quirk of the PHP standard library, the position of these two optional parameters is switched compared to json_decode(). Like its decoding counterpart, json_encode() accepts $flags and $depth parameters. PHP scalar types map directly into JSON with no transformation. PHP objects and associative arrays will become JSON objects containing all the enumerable property/key-value pairs of the input value. Data types are automatically handled to ensure they have an appropriate mapping in the generated JSON. PHP accepts any value as $value, except for resources. Example isset(), empty(), is_array() etc.Ĭhecking-object-before-conversion.Json_encode (mixed $value, int $flags = 0, int $depth = 512 ) : string | false ![]() PHP includes exclusive functions to verify data availability and its type. This method verifies if the input is an object. This example applies the is_object verification before converting a PHP object to an array. It is good programming practice to check the data availability before processing. $student = new student("5678", "William", "South Carolina", "Columbia", "US") The json_decode() converts the PHP object to array.Ĭonvert-class-object-into-array.php id = $id The json_encode() function prepares the JSON object to supply it for decoding. Then, the Student class instance is encoded to prepare object type data. The class constructor sets the properties of the object during the instantiation. This example constructs a PHP class object bundle. This is the output of the recursive PHP object to the array conversion program above. $object->address->state = "South Carolina" $object->address->shipping->zipcode = 1234 $object->address->shipping = new stdClass() $object->address->billing->zipcode = 9950 $object->address->email = new stdClass() It performs the conversion recursively on each level of the input object.Ĭonverting-recursive-object-to-array.php id = 5678 This program defines a custom function to convert a PHP object to array. The hierarchical object bundle is set as the input for the conversion process. It adds more properties at a nested level at different depths. This example uses an input object with depth = 3. Type-casting-to-convert-object-to-array.php id = 5678 It prepends the target data type enclosed with parenthesis. The PHP typecasting syntax is shown below. The output will be the same as we have seen above. It replaces the JSON encode decode via conversion with the typecasting statement. The below program uses the same input object. This is an alternate method to convert an object type into an array. This article includes examples of using both of the above methods to perform the object to array conversion. It supplied boolean true as a second parameter to get the output in an array format. The second method applies json_decode() on the given object. Typecasting is a straightforward method to convert the type of input data. Encoding and decoding object properties into an array of elements.There are two ways to achieve a PHP object to array conversion. If an object contains unassigned properties then it will return an array with numerical keys. When converting an object to array, the object property ‘name:value’ pairs will form an associative array. The below screenshot shows the output of this program.ĭifferent ways of converting a PHP object to array PHP object to array conversion in a line using json_decode id = 5678 Īfter decoding, the output array is printed to the browser.
