Why can't the closure function be called here? Also the Magic method has not been called

My code is like this:

   $value) $this->{$key}= $value;        The Public Function __call ($methodName, $params) {$params =array_merge (' stdobject ' = $this), $params); if (Isset ($this->{$methodName}) &&is_callable ($methodName)) {//$params is the parameter of the function, where the stdobject is            In the $stdobject;        Return Call_user_func_array ($methodName, $params);        } else {throw new Exception ("Fatal error:call to undefined method stdobject::{$methodName} ()"); }}}echo phpversion (); $obj = new Stdobject (); $obj->name = "Nick"; $obj->surname = "Doe"; $obj->age =; $obj-&G    T;adresse = null, $obj->getinfo = function ($stdObject) {//$stdObject referred to this object (Stdobject). Echo $stdObject->name. " " . $stdObject->surname. "Have". $stdObject->age. "yrs old." and live in ". $stdObject->adresse;}; Print_r ($obj); $obj->getinfo ();? >

First, as a matter of principle, call a class that does not exist in the middle of the member variable, because the display of the call magic method _set , but there is no way to display the declaration _set method;
2. Why can't I call the $obj->getinfo () method? An exception is thrown once the call is called
'Fatal error: Call to undefined method stdObject::getInfo(), it means that this method does not exist.

First of all, who made the indentation, quickly stand out, I promise not to kill you oh ... Also answer your question:

1. You know how to call a magic method when you call an inaccessible member variable __set() , so why don't you define it! You don't define how you make people work, it's like you don't give me the job, but do you want me to do it like a dog every day? Don't tease me, okay? Please add your own Magic method definition.

   class stdObject {    private function __set($name, $value) {        $this->$name = $value;    }}

2. The definition of member properties and member functions in PHP is not the same, I have not seen the use of $this->method = function() {} this definition of member functions, you are the idea of JavaScript into PHP. So when you invoke an inaccessible member function, the __call() magic method is triggered, your isset() judgment is true, but it is_callable() will return False (and here is a reminder of a clerical error, yes is_callable($this->$methodName) is_callable($methodName) , two is not exactly the same!) You think you put the variable name methodName you don't give $this the program will automatically call you a member function! What about the pit Daddy!! ), and then your syntax throws an exception out.

Dude you are teasing me. I will is_callable($methodName) turn into is_callable($this->{$methodName}) a successful run. My reason is wrong here. Rather than the Magic method. and achieved the effect I wanted. Now the code is this:

   $value) {$this->{$key}= $value; }}} Public function __call ($methodName, $params) {$params =array_merge (array (' Stdobject ' =&gt      ; $this), $params); if (Isset ($this->{$methodName}) &&is_callable ($this->{$methodName})) {//$params is the parameter of the function,        The stdobject here is the $stdobject in function;      Return Call_user_func_array ($this->{$methodName}, $params);     } else{throw new Exception ("Fatal error:call to undefined method stdobject::{$methodName} ()"); }}}; $obj = new Stdobject (); $obj->name = "Nick"; $obj->surname = "Doe"; $obj->age =; $obj->adresse = null;$    Obj->getinfo = function ($stdObject) {//$stdObject referred to this object (Stdobject). Echo $stdObject->name. " " . $stdObject->surname. "Have". $stdObject->age. "yrs old." and live in ". $stdObject->adresse;}; $obj->getinfo ();? >

The result of the operation is:
Nick Doe have 20 yrs old. And live in
First of all, I want to say that the foundation of dude is not very solid. $this->method = function () {} Of course you can define member functions like this. Also, calling a non-existent property does not necessarily show the specified _set method.

Here a simple class ' stdobject ', give us the possibility to create dynamic classes and the possibility to add and exec Ute methods thing that's StdClass ' don ' t let us do. Very useful if you extends it to a controller on MVC Design pattern. Let users create own classes.
I have the also post this class on http://www.php.net/manual/en/language.types.object.php
