PHP: Singleton Pattern for Composed Objects
I usually use a variation of the method below in classes that include a composed object (e.g., a database object):
For an example, see the _load_phpmailer method in my CeoFramework class.
// method: load composed object
function _load_object()
{
// already loaded
if ( is_object($this->ComposedObject) ) return;
require_once($this->PATH['composed_object_class']);
// create composite object
$this->ComposedObject = new ComposedObject();
// add additional config steps here
return;
}
// END method
function _load_object()
{
// already loaded
if ( is_object($this->ComposedObject) ) return;
require_once($this->PATH['composed_object_class']);
// create composite object
$this->ComposedObject = new ComposedObject();
// add additional config steps here
return;
}
// END method
For an example, see the _load_phpmailer method in my CeoFramework class.
