One of the things I've really liked about writing MooTools classes is
the syntax. After spending about a solid month working exclusively on
MooTools classes, when I went back to some PHP, I found I really
missed the options syntax for the class constructor, so I decided to
try to implement Moo-style options for PHP classes. This isn't really
anything special, but since it's inspired by MooTools, I thought I
would share because someone might find it interesting.
The options class:
<?php
class VMClass {
// @var array $options - The generic options array for which
extending classes should set default values
public $options = array();
/**
* Description: The setOptions method should be called in the
constructor of an extending class
* @param array $options - The options array resets any default
options present in the class
* @return - $this
*/
protected function setOptions($options) {
if (is_array($options)){
foreach ($options as $key => $value){
$this->options[$key] = $value;
}
$this->options = $this->arrayToObject($this->options);
}
return $this;
}
/**
* Description: Recursively returns an array as an object, for easier
syntax
* Credit: Mithras @
http://us2.php.net/manual/en/language.types.object.php#85237
* @param array $array - The array to return as an object
* @return - The object converted from the array
*/
public function arrayToObject(array $array){
foreach ($array as $key => $value){
if (is_array($value)) $array[$key] = $this-
>arrayToObject($value);
}
return (object) $array;
}
}
?>
A silly test class that extends the above class:
<?php
class TestClass extends VMClass {
public $options = array(
'name' => array('first'=>'Fred',
'last'=>'Flintstone'),
'question' =>'How are you?',
'useQuestion' => TRUE
);
function __construct($options = null){
$this->setOptions($options);
}
public function greet($salutation){
echo $salutation.', '.$this->options->name->first.'
'.$this->options-
>name->last.'. ';
if ($this->options->useQuestion) echo $this->options->question;
}
}
?>
And finally, a simple test case of our test class:
<?php
include('vmclass.php');
include('testclass.php');
$options = array('question'=>'Que pasa?', 'useQuestion'=>TRUE);
$foo = new TestClass($options);
$foo->greet('Howdy');
$foo->options->name->first = 'Wilma';
$foo->options->useQuestion = FALSE;
$foo->greet('Bonjour');
?>
