Hi Roman,

I'm not sure if I understand what you want to do - but if you try to set
your PHP-Variable with JavaScript it couldn't work.
JavaScript is Clientside interpreted and PHP is Serverside interpreted, that
means your PHP-Code is done before the JavaScript-Code.
So the Webserver reads your $color Variable and sees that it is set to
"<script><!--document.write(screen.colorDepth) file://--></script>"
This value is obviously not in your database. Then the Webserver sends the
resulting HTML to your browser.

>   $color = "<script><!--
>    document.write(screen.colorDepth)
>    file://-->
>    </script>";
>
>   $query = mysql_query("select id from color where color = '$color' ");
>   $a = mysql_num_rows($query);

Greetings
