note 105670 added to reflectionclass.newinstancewithoutconstructor

A good first use for this new method. It implements a transparent parser constructor argument to achieve 99% reusable component. <?php use ReflectionClass ; trait TSingleton { /** * Constructor. */ protected function __construct() {} /** * Drop clone singleton objects. */ protected function __clone() {} /** * Gets only one instance. * * @params Optional multiple values as arguments for the constructor. * @return Object instance from called class. */ public static function getInstance() { static $instance = null ; if ( ! $instance ) { $ref = new ReflectionClass( get_called_class() ) ; $ctor = $ref->getConstructor() ; // Thanks PHP 5.4 $self = $ref->newInstanceWithoutConstructor() ; // The magic. $ctor->setAccessible( true ) ; $instance = $ctor->invokeArgs( $self, func_get_args() ) ; } return $instance ; } } ?> ---- Server IP: 201.216.232.3 Probable Submitter: 186.23.111.32 ---- Manual Page -- http://www.php.net/manual/en/reflectionclass.newinstancewithoutconstructor.php Edit -- https://master.php.net/note/edit/105670 Del: integrated -- https://master.php.net/note/delete/105670/integrated Del: useless -- https://master.php.net/note/delete/105670/useless Del: bad code -- https://master.php.net/note/delete/105670/bad+code Del: spam -- https://master.php.net/note/delete/105670/spam Del: non-english -- https://master.php.net/note/delete/105670/non-english Del: in docs -- https://master.php.net/note/delete/105670/in+docs Del: other reasons-- https://master.php.net/note/delete/105670 Reject -- https://master.php.net/note/reject/105670 Search -- https://master.php.net/manage/user-notes.php
