Get a list of unique categories then get a list of each one would do it.
$link_id = mysql_connect($host, $usr, $pass) or die (mysql_error());
mysql_select_db($database, $link_id);
$sql="select distinct category from links";
$result = mysql_query($sql, $link_id) or die ("no results");
$cat_list = new Array();
while ($row=mysql_fetch_array($result))
{ $cat_list[] = $row["category"];
echo("<a
href=\"$PHP_SELF?#$category\">$category</font></a><br>");
};
foreach ($cat_list as $this_Cat)
{ echo("<a name=\"$category\">$this_Cat</font></a><br>");
$sql="select name, url from links where category =
'$this_Cat'";
$result = mysql_query($sql, $link_id);
while ($row=mysql_fetch_array($result))
{ echo ("<a href='" . $row[url] . "'>" . $row["name"]
. "</a><br>");
};
}
haven't tested this but the principal should be okay and do what you're
after
