RE: [PHP] newbie question about variables

Yes, you were right, this works just the way you wrote. And yes, there is a JavaScript way to do it, but I guess PHP is better for this kind of jobs. JavaScript is using your browser as it's 'server' while PHP uses your remote server. Therefore, all PHP will do is generate HTML code to send to client. Make a way it dynamically assigns you the right image and, vuala! Just if you would have coded that HTML page yourself. No JavaScript.

Do the variables get saved on the client machine? Do they have to be specifically passed from page to page and back? Are they automatically returned to the calling page? If I have a page with thumbnail, and I'd like to call a page that dynamically places the original photo into it (based on the thumbnail clicked) does it go a little something like this? in index.html: <a href="picture.html?var=pictureone.jpg"><img src="thumbnail.gif"></a> in picture.html <a href="index.html"><img src="<?php print $var ?>"</a> Is there a similar javascript method?
