Exit script early

Ok, So I'm creating a details.php page where I'm expecting the url to be something like: /details.php?id=12345 Thus in my php I have the following: if (!isset($id)) { // if no id exsits // Create a page saying ID not found, goto index writeHTMLTag(); writeHeader("Error", "never"); writeBodyTag(); writeLogoNav(); echo "<h1>Error: A hospital ID was not found.</h1> <p>Goto: <a href=\"index.php\">Nursing Career Match</a> "; writeFooter(); writeHTMLTagCloser(); // what command can I use to end the script right here? } else { // Run MySQL stuff and display page } My question is "what command can I use to end the script [inside the top part of that if statement]?" ~ Mike -- Mike Zornek | Project Leader Apple Student Developers The Insanely Great Site with the Insanely Long URL http://www.applestudentdevelopers.org Personal Site: http://www.mikezornek.com
