Build recursive nested menu from array

Question

I\'m trying to build a recursive menu which would look something like this when finished, with an infinite amount of nested items:

Answer 1

This is my example code to build nested menu for Zurb Foundation, using recursive function in PHP. Very simple and clean.

// call the function
build_menu();

//----------------------------

// recursive function
function build_menu($parent = "", $tab=""){
    $sql = "SELECT * FROM cat WHERE parent='$parent' ORDER BY category ASC";
    $q = mysql_query($sql);
    if (mysql_num_rows($q)) {
        if (empty($parent)):
            print $tab."
\n";
        else:
            print $tab."
\n";
        endif;
        while($d = mysql_fetch_object($q)) {
            $has_child = mysql_num_rows(mysql_query("select * from cat where parent='$d->code'") );
            $tag = ($has_child ? " class='has-dropdown'" : "");
            $nl  = ($has_child ? "\n" : "");

            print $tab."\t"."$d->category$nl";

            if ($has_child) build_menu($d->code, $tab."\t");

            print $tab."\n";
        }
        print $tab."
\n";
    }
}
