__get and __set ??

Tanax · 11-17-2007, 08:03 PM

Hi.

Can someone please explain how they work?

PHP Code:


			
private $tables = array();

public function __set($field, $value) {



$this->tables[$field] = $value;



}



public function __get($field) {



return $this->tables[$field];



}

PHP Code:


			
$object->user_name = 'user_name';

$object->user_reg_date = 'register_date';

That would set tables['user_name'] to user_name, and tables['user_reg_date'] to register_date.

However, how do I GET them??

PHP Code:


			
echo $object->user_reg_date;

???

Added Geshi Syntax Highlighting :)

[highlight=php] var myVar = myFunc(myArg); [/highlight]

Here's another very useful 'tutorial' to learn the Magic functions!

I don't see a point in using set. How can you set variables which doesn't exists in the class?

Tanax · 11-19-2007, 03:52 PM

Lol, what??

I'm not setting a variable..

Magic methods, Haris. Crazy, but it's what PHP have gone for. Makes things like this easier if you wish to simply set and get many variables.

But I'm not setting a variable? =//

I'm just assigning a value to a key in the array tables...
