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:

Yah, remember that the code I used for that pagination class I wrote is quite old. Anyhow, to the function, I just returned an array because I felt it would be easier.

You however, could create 2 functions for it.

PHP Code:


			
$starting_no = $pagination->getStart();

$end_cound = $pagination->getEnd();

Surely you can do them staticly, but remember you need to set the class variables to public then - which I strongly advice you not to do, 'cause then you can also accidently change the value aswell Classname::$variable = "bogus" which, needless to say, is quite a security issue.

It's safer to have a method instead to fetch a private classvariable, that way you can be sure that it's only able to return the current value, and never change it.
