It's because $this is a reserved word used with classes to reference the current object. For example

class TestClass
{
    var $blah;    
    function setBlah($input)
    {
        $this->blah = $input;
    }
}
class TestClass
{
    var $blah;

Re: Paging Problem

Sep 30th, 2007

hi.
1. First I open it, I just see the Link Navigation the even numbers mean (0 2 4 6 8 Next Next8)
2. When I click on any of the navigation link, I see the address bar like below:
php_pagin.php?start=2&p_f=0
php_pagin.php?start=4&p_f=0
php_pagin.php?start=6&p_f=0
php_pagin.php?start=8&p_f=0

means just in the address bar the number changes, nothing else happens in the page

i looked over the entire code line by line and really didn't see anything wrong. i took out all of the comments and stuff so i could read it better, made a few changes. i think it might work.
