<?php

foreach ($arguments as $property => $argument) {
$this->{$property} = $argument;

} else {
throw new Exception("Fatal error: Call to undefined method stdObject::{$method}()");
}
}
}

// Usage.

$obj = new stdObject();
$obj->name = "Nick";
$obj->surname = "Doe";
$obj->age = 20;
$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;
};

$func = "setAge";
$obj->{$func} = function($stdObject, $age) { // $age is the first parameter passed when calling this method.
$stdObject->age = $age;
};

$obj->setAge(24); // Parameter value 24 is passing to the $age argument in method ‘setAge()‘.

// Create dynamic method. Here i‘m generating getter and setter dynimically
// Beware: Method name are case sensitive.
foreach ($obj as $func_name => $value) {
if (!$value instanceOf Closure) {

$obj->{"set" . ucfirst($func_name)} = function($stdObject, $value) use ($func_name) { // Note: you can also use keyword ‘use‘ to bind parent variables.
