[phpDave]

Im new to php. Im trying to display data via url. (example) www.mySite.com/usercomment?user_id=1. I would like to let users retreive data by having to type in specific url. Not pageing through data. Any comments, suggestions would be appreciated

You can get PHP parameters (the things after the ?), by using $_GET. In your case you'd go:

$variable = $_GET["user_id"];

Unless I got your question wrong and you're asking something else?

What do you mean 'type in an url'. The url given as an example contains a 'querystring' - a list of parameter-value pairs. Don't have your users type this as they probably wouldn't know what to type. These urls are usually pre-written into links. THe previous post mentions using $_GET to retrieve the value - this is correct. However, you could get a nasty error unless you check for its existence first:

if(isset($_GET['user_id'])){
   $user_id = $_GET['user_id'];
}
