The screen resolution of the server or the client?
To get the resolution of the server you would have to use the exec() function and execute the unix/dos command to get the resolution (are there any?)

But you probably mean the client, which you would use JavaScript

<script type="text/javascript"> 

  document.write(window.screen.width + ' x ' + window.screen.height); 

</script> 

You can write the resolution to a cookie and use the php cookie functions to grab the resolution from the cookie file.

How would you compare the value?

if(<script type="text/javascript"> 
  document.write(window.screen.width + ' x ' + window.screen.height); 
</script> < 1024)
echo "Error";

Im pretty sure if you want to use php to display the error message you have to use cookies, unless there is another way to store the width/height. You could always of course display the error in JavaScript. Im no JS expert but maybe something like this

<script type="text/javascript">
if(window.screen.width < 1024)
allert("Your screen is too small");
</script>
