Add method in an std object in php

Question

Is it possible to add a method/function in this way, like

$arr = array(
    \"nid\"=> 20,
    \"title\" => \"Something\",
    \"value\" => \"Somethi         


        

Answer 1

You cannot dynamically add a method to the stdClass and execute it in the normal fashion. However, there are a few things you can do.

In your first example, you're creating a closure. You can execute that closure by issuing the command:

$arr['my_method']('Argument')

You can create a stdClass object and assign a closure to one of its properties, but due to a syntax conflict, you cannot directly execute it. Instead, you would have to do something like:

$node = new stdClass();
$node->method = function($arg) { ... }
$func = $node->method;
$func('Argument');

Attempting

$node->method('Argument')

would generate an error, because no method "method" exists on a stdClass.
