Double quotes question

Hi, I have a script that lists the files in a directory, and create links accordingly but if the files contain spaces then the link won't come out correctly. I am fairly new to PHP and have no real idea on how I can get it to make links show as <a href="link"></a> currently it will put links like <a href=link></a> which is causing the problem. Below is the script. [script] <? function directory($result) { $handle=opendir("."); while ($file = readdir($handle)) { if ($file == "." || $file == "..") { } else { print "<a href=$file>$file</a><br />\n"; } } closedir($handle); return $result; } ?> [/script] I did try going else { print "<a href="$file">$file</a><br />\n"; } but all I get is PHP errors doing this until the double quote is removed, any help in this would be great.
