Here a simple class 'stdObject' that give us the possibility to create dynamic classes and
the possibility to add and execute methods thing that '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 also post this class on http://www.php.net/manual/en/language.types.object.php
<?php
class stdObject {
public function __construct(array $arguments = array()) {
if (!empty($arguments)) {
foreach ($arguments as $property => $argument) {
$this->{$property} = $argument;
}
}
}
public function __call($method, $arguments) {
$arguments = array_merge(array("stdObject" => $this), $arguments); // Note: method
argument 0 will always referred to the main class ($this).
if (isset($this->{$method}) && is_callable($this->{$method})) {
return call_user_func_array($this->{$method}, $arguments);
} else {
throw new Exception("Fatal error: Call to undefined method
stdObject::{$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.
$stdObject->{$func_name} = $value;
};
$obj->{"get" . ucfirst($func_name)} = function($stdObject) use ($func_name) {
// Note: you can also use keyword 'use' to bind parent variables.
return $stdObject->{$func_name};
};
}
}
$obj->setName("John");
$obj->setAdresse("Boston");
$obj->getInfo();
?>
