Tanax, this might look familiar to you....

Code:

function viewPage() {

//DO SOMETHING HERE AND RETURN DATA

$viewPageEntry[] = $this->starting_no;
$viewPageEntry[] = $this->end_count;
return $viewPageEntry;

}

In my HTML I am calling it and then assigning it to a variable,
then accessing each data this way.

Code:

$getViewPage = $pagination->viewPage();

echo $getViewPage[0];
echo $getViewPage[1];

I thought maybe OO was a bit more powerful or had a better way to access its data?

I thought maybe I would be able to access the data this way but it doesn't work.

Code:

echo $pagination->viewPage(starting_no);
echo $pagination->viewPage(end_count);

Maybe I should access it statically? Would that work?

Code:

$getViewPage::starting_no
$getViewPage::end_count

I get this error when I try the above code:

Paamayim Nekudotayim means "Double colon" in hebrew.

You cannot call a property like that in versions prior to PHP 5.3, in 5.3 and newer it will call the constants named 'starting_no' and 'end_count'. To call a property staticlly you need to call it with a class name:

PHP Code:


			
echo ClassName::$property;

The following will call a constant:

PHP Code:


			
echo ClassName::CONSTANT;

or inside a class you can use self:: and parent:: instead of the class name if you are within a method scope of the class.

In PHP 5.3 the following is possible:

PHP Code:


			
class A

{

    public static $b;





    public function __construct()

    {

        /* Sets A::$b staticlly */

        $this::$b = 'ABC';

    }

}



$a = new A;

echo '$a::$b: ' . $a::$b . PHP_EOL;

echo 'A::$b: ' . A::$b . PHP_EOL;

It will print:

Code:

$a::$b: ABC
A::$b: ABC

Because the dynamic syntax is possible here ;)
