Call a function when I access a property (PHP magic methods) -

basically i'm using php overloading create dynamic methods , properties. want trigger function property access keeping access methods.

in other terms, that's php code:

first class:

class _class {     private $_instance;      public function __construct() {         $this->_instance = new _object();     }      public function __get($name) {         switch ($name) {             case "instance":                 //logics                 break;         }         return null;     } } 

second class:

class _object {     public function __call($method, $args) {         switch ($method) {             case "method":                 //logics             break;         }         return null;     } } 

now want execute function when access object property in way:

$obj = new _class(); echo $obj->instance; //some output here, executing function echo $obj->instance->method(); //different output, executing method of instance 

thanks, appreciated!

when instantiate first class, create $this->_instance instead $obj->instance. so $obj->instance null , can not call on that.

but, if try $obj->_instance->method();, bad also, because _instance private. need add getter. try this:

class _class {      private $_instance;      public function __construct() {         $this->_instance = new _object();     }      public function __get($name) {         switch ($name) {             case "instance":                 echo "instance";                 break;         }         return null;     }      public function getinstance() {         return $this->_instance;     }  }  class _object {      public function __call($method, $args) {         switch ($method) {             case "method":                 echo "method";                 break;         }         return null;     }  }  $obj = new _class(); $obj->instance;  $obj->getinstance()->method(); 

output is:

instance method
