rename the file to have a php extension
then, in your html code...
<php>if($country == "en"){
echo "<A HREF=\"en.php\">English Link</A>";
}
</php>
the <php> tags tell the parser to parse the stuff in the tags
oh, start by reading the manual (www.php.net/manual) and the tutorial (www.php.net/tut), and then put a descriptive subject line - "help with php" is crap - this is a php forum, everyone here wants php help...
