menu navigazione in php

[falampi]

come post precedente, chi fa da se fa per tre ...che se aspetto voi... :P
scherzi a parte, dopo aver capito che sti cazzarola di trail nav in realtà si chiamano breadcrumb è stato tutto più semplice.
ho trovato questo, me lo sono adattato e funziona alla grande!
quindi ve lo posto così se qualcun altro ha lo stesso dilemma, sa come fare...

pagina da salvare come breadcrumb.php

function breadCrumb($PATH_INFO) {
    global $page_title, $root_url;

    // Remove these comments if you like, but only distribute 
    // commented versions.
    
    // Replace all instances of _ with a space
    $PATH_INFO = str_replace("_", " ", $PATH_INFO);
    // split up the path at each slash
    $pathArray = explode("/",$PATH_INFO);
    
    // Initialize variable and add link to home page
    if(!isset($root_url)) { $root_url=""; }
    $breadCrumbHTML = 'Sei in [url="'.$root_url.'/"]Home[/url] &gt; ';
    
    // initialize newTrail
    $newTrail = $root_url."/";
    
    // starting for loop at 1 to remove root
    for($a=1;$a<count($pathArray)-1;$a++) {
        // capitalize the first letter of each word in the section name
        $crumbDisplayName = ucwords($pathArray[$a]);
        // rebuild the navigation path
        $newTrail .= $pathArray[$a].'/';
        // build the HTML for the breadcrumb trail
        $breadCrumbHTML .= '[url="'.$newTrail.'"]'.$crumbDisplayName.'[/url] &gt; ';
    }
    // Add the current page
    if(!isset($page_title)) { $page_title = "Pagina corrente"; }
    $breadCrumbHTML .= '[b]'.$page_title.'[/b]';
    
    // print the generated HTML
    print($breadCrumbHTML);
    
    // return success (not necessary, but maybe the 
    // user wants to test its success?
    return true;
}

?>

quindi per richiamarlo, nelle vostre pagine metterete di volta in volta una roba simile:

$page_title = "Contatti";
include("breadcrumb.php");
breadCrumb($_SERVER['REQUEST_URI']); 

spero serva a qualcuno di voi che magari stava impazzendo come me!
