Galley automatica da cartella

[calogeromancuso]

Scusami, ho fatto veloce e non mi ero accorto che era formattato male. Ecco il codice formattato bene:

$filetypes  = array(".png", ".PNG", ".jpg", ".JPG", ".jpeg", ".JPEG", ".gif", ".GIF");
$basedir    = './immagini/gallery';
$currentdir = '';
if(isset($_GET['f']) ? $_GET['f'] : '')
    {
    $currentdir = '/'.$_GET['f'].'/';
    }

function scandirSorted($path)
    {
    $sortedData  = array();
    $data1       = array();
    $data2       = array();
    foreach(scandir($path) as $file)
        {
        if(!strstr($path, '..'))
            {
            if(is_file($path.$file))
                {
                array_push($data2, $file);
                }
            else
                {
                array_push($data1, $file);
                }
            }
        }
    $sortedData = array_merge($data1, $data2);
    return $sortedData;
    }

function strpos_arr($haystack, $needle)
    {
    if(!is_array($needle))
        {
        $needle = array($needle);
        }
    foreach($needle as $what)
        {
        if(($pos = strpos($haystack, $what)) !== false)
            {
            return $pos;
            }
       }
    return false;
    }

function addThumb($filename)
    {
    $filename    = array_reverse(explode('.', $filename));
    $filename[0] = 'smpgthumb.'.$filename[0];
    $filename    = implode('.', array_reverse($filename));
    return $filename;
    }

if(is_dir($basedir.$currentdir))
    {
    $folder = array_diff(scandirSorted($basedir.$currentdir), array('..', '.', 'Thumbs.db', 'thumbs.db', '.DS_Store'));
    }

foreach($folder as $item)
    {
    if(!strstr(isset($_GET['f']), '..'))
        {
        if(!strstr($item, 'smpgthumb'))
            {
            if(strpos_arr($item, $filetypes))
                {
                if(file_exists($basedir.$currentdir.'/'.addThumb($item)))
                    {
                    echo('<a href="'.str_replace('//', '/', str_replace(' ', '%20', $basedir.$currentdir.'/'.$item)).'" data-lightbox="roadtrip"><img src="'.str_replace('//', '/', str_replace(' ', '%20', $basedir.$currentdir.'/'.addThumb($item))).'" class="img" alt=""></a>');
                    }
                else
                    {
                    echo('<a href="'.str_replace('//', '/', str_replace(' ', '%20', $basedir.$currentdir.'/'.$item)).'" data-lightbox="roadtrip"><img src="php/thumb.php?file='.str_replace('//', '/', str_replace(' ', '%20', $basedir.$currentdir.'/'.$item)).'" class="img" alt=""></a>');
                    }
                }
            else
                {
                echo('<a href="?f='.str_replace('//', '/', str_replace(' ', '%20', $currentdir.'/'.$item)).'">'.$item.'</a>');
                }
            }
        }
    }
