Speed issue

[Ravani]

Hi everyone,

 

I was discussing this topic with one of my friends and both of us can't give a real answer to this.

 

Example:

class test {
    function a(){
      $obj = new DB_TableObject();
      
      //blabla bla
      
      $this->b($obj);
   }

   function b($object){
      $object->getResults();
   }
}

 

class test {
   function a(){
      $obj = new DB_TableObject();

      //blabla bla

      $this->b($obj);
   }

   function b(){
      $obj = new DB_TableObject();
      $object->getResults();
   }
}

 

Which one is better? The first or the second solution?

Is something like this better for you?

 

<?php
class test {

	public function __construct() {
		$this->object = new DB_TableObject();
	}

	public function returnResults() {
		$this->object->getResults();
	}
}
?>

James is right.  You can also look into instances singleton classes, so you can just say DB_Object::getInstance() every time, which always returns the same memory location.

Thanks a constructor would be a good solution indeed, however it seems that the Zend Framework has trouble with that.

 

So using  DB_Object::getInstance() will be a good solution as well?

[ManiacDan]

Zend framework doesn't have a problem with constructors, they're critical to OOP development. What makes you think it has a problem?

[jamesxg1]

Dan's right here Ravani, Zend has no issue with constructors. When it comes to OOP programming constructors are essential.

You're right, however I'm getting this error:

 

Fatal error: Declaration of LoginController::__construct() must be compatible with that of Zend_Controller_Action_Interface::__construct() in

 

Seems like I need to add some arguments in the constructor but I don't really know which one.

[ManiacDan]

Whichever ones are in the Zend_Controller_Action_interface constructor.

 

Look into inheritance in OOP PHP.
