![]() Example isset(), empty(), is_array() etc.Ĭhecking-object-before-conversion. 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. Definition and Usage The jsondecode () function is used to decode or convert a JSON object to a PHP object. 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. If the json cannot be decoded or if the encoded data is deeper than the recursion limit then it returns NULL. Return values: This function returns the encoded JSON value in appropriate PHP type. When converting an object to array, the object property ‘name:value’ pairs will form an associative array. options: It includes bitmask of JSONOBJECTASARRAY, JSONBIGINTASSTRING, JSONTHROWONERROR. The below screenshot shows the output of this program.ĭifferent ways of converting a PHP object to array It will return string as is, since string is a valid value in JSON.PHP object to array conversion in a line using json_decode id = 5678 Īfter decoding, the output array is printed to the browser. Let's see how you can convert a PHP string to JSON. Examples How to Convert PHP String to JSON The json_encode() function returns JSON encoded string if the function succeeded or if it fails, then it will return false. By default, it is set to 512, must be greater than 0. depth: It sets the maximum depth of the given value (array), the function can work with.flag: It is a bitmask consisting of JSON constants like JSON_FORCE_OBJECT, JSON_HEX_QUOT, JSON_HEX_TAG, JSON_HEX_AMP, JSON_HEX_APOS, JSON_INVALID_UTF8_IGNORE, JSON_INVALID_UTF8_SUBSTITUTE which can affect how function encodes the given value. ![]() All string data must be valid UTF-8 encoded. Normally, you would pass PHP array to convert it to JSON string. It can be of any type except Resource type. ![]()
