This example describes the usage of the Registrar mode class in PHP. Share to everyone for your reference, specific as follows:

Register Read and Write class

<?php/** * Register read-Write class */class Registry extends Arrayobject {/** * Registry instance * * @var object/P
  rivate static $_instance = null;
    /** * Obtain Registry instance * * @note single piece Mode * * @return object/public static function getinstance () {
      if (self::$_instance = = null) {self::$_instance = new self ();
    echo "New Register object!";
  return self::$_instance; /** * Save one content to the registry * * @param string $name index * @param mixed $value data * * @return void/Pub
  Lic static function set ($name, $value) {self::getinstance ()->offsetset ($name, $value); /** * Gets the value of an item in the registry * * @param string $name Index * * @return Mixed/public static function get ($n
    AME) {$instance = Self::getinstance ();
    if (! $instance->offsetexists ($name)) {return null;
  Return $instance->offsetget ($name); /** * Check if an index exists * * @param string $name Index * * @reTurn Boolean/public static function isregistered ($name) {return self::getinstance ()->offsetexists ($name)
  ; /** * Deletes the specified entry in the registry * * @param string $name index * * @return void/public static function remove ($n
  AME) {self::getinstance ()->offsetunset ($name);

Classes that need to be registered

   function hello ()
   {
    echo "Hello World";
    return;
   }

require_once "Registry.class.php";
Require_once "test.class.php";
New A object
$test =new test ();
$test->hello ();
Registered Object
registry::set (' TestClass ', $test);
Remove Object
$t = Registry::get (' TestClass ');
Call object Method
$t->hello ();
