do not use
if($page = LAST_PAGE)

better use
if($page == LAST_PAGE) {
…
}

due to readability und prevent side-effects

This is definitely possible but this question doesn’t really belong here.. I recommend asking on this website: http://stackoverflow.com/

Hi Jonah, thanks for the info. Wonderfing if you could assist me. Looking for a php code to do the following. I’d like to show a swf banner 400×92 pixels on a page. However if the banner file can’t be found in a folder called “banners” then I would like it not to show.
If BANNER1.SWF is found, show it, else leave blank.
if BANNER2.SWF is found, show it, else leave blank.
and so on for about 8 banners.
Is there anyway that when it’s left blank that it doesn’t take up that space? Meaning, the page would move up?

Thanks ahead of time.
David

Ah the good old Ternary Operator (See more: http://en.wikipedia.org/wiki/Ternary_operation). Available in other languages too.

I didn’t know about the AND and OR operators! Thanks
