PHP Recursive Directory Menu

I think similar questions have been asked before, but I can't quite wrap my head around whether what I want to do is logicaly possible. I currently use DDSmoothMenu on our intranet

Solution 1:

A recursive solution could look something like:

function createMenuHTML($dir){
    $html = "";
    if(is_dir($dir)){
        //Directory - add sub menu
        $html .= "<li><a href='#'>Sub Menu Name</a><ul>";
        if ($dh = opendir($dir)) {
            while (($file = readdir($dh)) !== false) {
                $html .= createMenuHTML($dir.$file);
            }
            closedir($dh);
        }
        $html .= "</ul>"
    }else{
        //File so  just add list item
        $html .= "<li><a href='#'>".basename($dir)."</a></li>"
    }
    return $html;
}

This is entirely untested but should hopefully help.

Solution 2:

The easier way is use trees. I recommendNested model You can check current and perv lvl of item.

Solution 3:

Ok, so here is what I ended up with thanks to Jim's example code:

    function createMenu($dir) {
    if(is_dir($dir)) {
        echo "<li><a href='#'>".basename($dir)."</a><ul>";
        foreach(glob("$dir/*") as $path) {
            createMenuHTML($path);
        }
        echo "</ul></li>";
    }
    else {
        $extension = pathinfo($dir);
        $extension = $extension['extension'];
        echo "<li><a href='$dir'>".basename($dir, ".".$extension)."</a></li>";
    }
}

createMenu("/public/Documents");

Works like an absolute charm for my DDSMoothMenu, and I can be as general or as granular as I want when using the function to create the menu.

I will mark this as the answer, but Jim gave me the best starting point possible code wise!
