I'm trying to make a prototype of a simple plugin system I plan on implementing into one of my projects. I have 4 files:
Index.php
Plugins/__BASE.php
Plugins/Sample.php
The index file checks if the 'oncall' method belongs to a class in the Plugins folder using functions I defined in the Plugins
class ( __BASE.php
). If it does exist, it will execute it.
require_once 'Plugins/__BASE.PHP';
$func = 'oncall';
$plugins = new Plugins();
if($plugins->IsPluginMethod($func)) {
$obj = $plugins->GetObject($func);
call_user_func(array($obj, $func));
}
else
echo "'$func' isn't part of a plugin!";
__BASE.php
is the base plugin class which all of the plugins will extend. It has two methods: IsPluginMethod()
and GetObject()
. IsPluginMethod checks if the method name supplied belongs to a class and GetObject returns an instance of the class the method belongs to.
class Plugins {
public $age = "100";
public function IsPluginMethod($func) {
foreach(glob('*.php') as, $file) {
if($file != '__BASE.php') {
require_once $file;
$class = basename($file, '.php');
if(class_exists($class)) {
$obj = new $class;
if(method_exists($obj, $func))
return true;
else
return false;
}
}
}
}
public function GetObject($func) {
foreach(glob('*.php') as $file) {
if($file != '__BASE.php') {
require_once $file;
$class = basename($file, '.php');
if(class_exists($class)) {
$obj = new $class;
return $obj;
}
}
}
}
}
Sample.php is a sample plugin which prints $this->age which is defined in the Plugins class.
class Sample extends Plugins {
public function oncall() {
echo "Age: {$this->age}";
}
}
This is what I see in index.php:
'oncall' isn't part of a plugin!
Can anyone help? Thanks.
在__BASE.php文件中,将(glob('*.php')
更改为glob('Plugins/*.php')
