PHP Function Overloading - How to?

public function makeTweet( $DatabaseObject, $TextObject, $MessageObject)
{
    if( $DatabaseObject == NULL )
    {
        $DatabaseObject = new Database();
        $TextObject = new Text();
        $MessageObject = new Message();
    }
    $TweetObject = new ControlTweet();        
    $TweetObject->setObjects($DatabaseObject, $TextObject, $MessageObject);
    return $TweetObject;
}

PHP functions can be "overloaded". Use func_get_args and set no variables in the function.

You could also submit an associative array as a single variable. Then you can use extract inside the function to make friendly variables.

$vars = array('key1'=>'value1','key2'=>'value3');

function function_name($v){
     extract($v);

    //do something
}

For the function to behave differently you would need to determine what your variables are. In this way you can mirror the overloading idea.

You can add optional parameters in the function declaration like:

public function makeTweet( $DatabaseObject, $TextObject, $MessageObject = null)

Now you can either do:

$obj->makeTweet($db, $text, $messageObj);

or

$obj->makeTweet($db, $text);

This is the closest you can get in PHP.

You cannot overload a function in PHP. See this page for reference: http://www.daniweb.com/web-development/php/threads/19978/overloading-php-functions
