PHP Reflection Class Reflectionclass usage Analysis _php technique

This example describes the Reflectionclass usage of PHP reflection classes. Share to everyone for your reference, specific as follows:

Let's look at a piece of code:

/** * @name PHP Reflection api--The plug-in system architecture implemented using reflection technology * @author:P hpcq.com * * Interface Iplugin {public static function getName ();
 function Findplugins () {$plugins = array ();
  foreach (Get_declared_classes () as $class) {$reflectionClass = new Reflectionclass ($class);
  if ($reflectionClass-> Implementsinterface (' Iplugin ')) {$plugins [] = $reflectionClass;
} return $plugins;
 function Computemenu () {$menu = array (); foreach (Findplugins () as $plugin) {if ($plugin-> Hasmethod (' Getmenuitems ')) {$reflectionMethod = $plugin-
   > GetMethod (' Getmenuitems ');
   if ($reflectionMethod-> IsStatic ()) {$items = $reflectionMethod-> Invoke (NULL);
    else {$pluginInstance = $plugin-> newinstance ();
   $items = $reflectionMethod-> Invoke ($pluginInstance);
  } $menu = Array_merge ($menu, $items);
} return $menu;
 function Computearticles () {$articles = array (); foreach (Findplugins () as $plugin) {if ($plugin-&GT
   Hasmethod (' Getarticles ')) {$reflectionMethod = $plugin-> GetMethod (' getarticles ');
   if ($reflectionMethod-> IsStatic ()) {$items = $reflectionMethod-> Invoke (NULL);
    else {$pluginInstance = $plugin-> newinstance ();
   $items = $reflectionMethod-> Invoke ($pluginInstance);
  } $articles = Array_merge ($articles, $items);
} return $articles;
} require_once (' plugin.php ');
$menu = Computemenu ();
$articles = Computearticles ();
Print_r ($menu);

 Print_r ($articles);

The plugin.php code is as follows:

<?php
class Mycoolpugin implements Iplugin
{public
 static
 function GetName ()
 {return
  ' Mycoolplugin ';
 }
 public static
 function Getmenuitems ()
 {return
  array (' description ' => ' mycoolplugin ', ' link ' = > '/mycoolplugin ');
 }
 public static
 function Getarticles ()
 {return
  array (' path ' => '/mycoolplugin ', ' title ' => ') This is a really cool article ', ' text ' => xxxxxxxxx);
 }

The code above is an application of the PHP reflection class.

What is a PHP reflection class, as its name suggests, can be understood as a mapping of a class.

As an example:

Class Fuc {//Definition of a classes
 static
 function ec () {
  echo ' I am a class ';
 }
}
$class =new reflectionclass (' fuc '); Create a reflection class of fuc this class

As for $class what is in this reflective class, you can view the manual, which is unknown.

$FUC = $class->newinstance (); Equivalent
to the instantiation of the Fuc class $fuc->ec ();//implementation of methods in FUC EC/
* Final output: I am a class/

And some of the more advanced uses

$ec = $class->getmethod (' EC '); Obtain the EC method in the Fuc class
$fuc = $class->newinstance ();//Instantiate
$ec->invoke ($FUC);   Implementation of EC methods

The procedure above is very familiar. is actually similar to the method of calling the object

But here is the reverse, the method in front of the object in the back
