README
This is a simple package that contains forward compatibility classes and interfaces that are registered to the global namespace
Deprecated
The joomla/compat
package has been deprecated. No further updates are planned.
JsonSerializable
JsonSerializable
is a PHP 5.4 interface that allows you to specify what data to serialize to JSON when you json_encode
an object that implements the interface.
Usage
Since this is a PHP 5.4 interface, the jsonSerialize()
method does not get called automatically when json_encode
-ing an instance of the class when used in 5.3. To work around this, simply call the jsonSerialize()
method directly when passing it to json_encode
. This is forward-compatible with PHP 5.4.
Note in some instances of PHP 5.5 from Debian the interface is also missing (see http://stackoverflow.com/questions/18239405/php-fatal-error-call-to-undefined-function-json-decode) which will also require this interface to be included.
class MyClass implements \JsonSerializable { /** * @var array Holds the data this class uses. */ protected $data; public function __construct(array $data) { $this->data = $data; } public function jsonSerialize() { return $this->data; } } $obj = new MyClass(array('sample', 'data', 'to', 'encode')); $encoded = json_encode($obj->jsonSerialize());
