one object

[David Nguyen]

Hello,
I want to build one object that will be reuse all the time, so I just
need to create it once for all, how can I do that. A sort of static object.
Thanks

Depending on how you want to use it (application or page wide) you could
settle for a session reference to the object or a singleton class (or a
combination of both).

When you do not know what a singleton is, here are some examples:

PHP 4:

PHP 5:

class Singleton {
private static $_instance = null;

public static function getInstance () {
if (self::$_instan ce == null) {
self::$_instanc e = new self;
}
return self::$_instanc e;
}
}

$singleton = Singleton::getI nstance();
