[PHP] first output from for-loop?
Hi,
I'm trying to figure out how to display a VIDEOID from a class when a variable is empty.
in the HTML part <?=$service->view($tag)?> outputs 12 videos, but what i'm try to obtain is additionally the 1st VIDEOID as a preview at domain.com/keyword/
.htaccess
index.php
Thanks for help

PHP Code:
RewriteEngine on
RewriteRule ^([^/.]+)/$ index.php?tag=$1 [L]
RewriteRule ^([^/.]+)/results-([0-9]+)/$ index.php?tag=$1&page=$2 [L]
RewriteRule ^([^/.]+)/([^/.]+)$ index.php?tag=$1&video=$2 [L]
PHP Code:
class Youtube
{var $dom, $idvideo, $title, $video, $VIDEOID;
function pagination()

function tag($tag, $page = 1)
{if ($page <= 0) $page = 1;

}
$service = new Youtube;
$tag = isset($_GET['tag'])?htmlentities($_GET['tag']):$tag = str_replace(' ', '-', $keywords[0]);
