JavaScript to PHP.. Can you help this code conversion?

[rawkinrich]

Hi all,

How can you write the following in PHP?

<SCRIPT LANGUAGE="JavaScript">
<!-- Begin
//document.write('Your settings are ' + screen.width + ' x ' + screen.height + '');
if (screen.width == 640) {
document.write('<img src="/images/footer-left800.gif" width="78" height="18" border="0" alt="Main Man Kennels">');
}
if (screen.width == 800) {
document.write('<img src="/images/footer-left800.gif" width="78" height="18" border="0" alt="Main Man Kennels">');
}
if (screen.width == 1024) {
document.write('<img src="/images/footer-left.gif" width="88" height="20" border="0" alt="Main Man Kennels">');
}
if (screen.width == 1280) {
document.write('<img src="/images/footer-left.gif" width="88" height="20" border="0" alt="Main Man Kennels">');
}
if (screen.width == 1600) {
document.write('<img src="/images/footer-left.gif" width="88" height="20" border="0" alt="Main Man Kennels">');
}
// End -->
</script>

I want spiders etc to be able to see the image, and the browser to determine screen resolution.

unfortunatelly PHP cannot determine the screen width without JavaScript.
why all those "IF" 's ?- seems to me that you have only 2 images to swap-you can ignore the 640*800 users(or make a special page for them), they are under 9% and because of them a code gets executed on every page view...

You could however use the javascript code in a dynamic include that you could feed to the page depending on if it was a Bot or a Browser Visiting.

java script is made to be a user side scripting language, while php is made to be server side. PHP has very limited access to any of the users information, thus you can not really incorporate both into 1 system, unless it's basic coding.
