从php中的关联数组中删除文件路径

I am trying to get all files in a folder. The files are images along with one extra file named as "Thumbs.db"

fOLLowing is my code

$path = $ringPaths[$i];
        $dirname =   substr( $path ,0, -4 );
        $lastpart = basename( $dirname , ".zip");
        $abspath = substr( $dirname ,strpos( $dirname, "com/")+4 );
        $direcotypath = "../".$abspath."/".$lastpart;

        $files = glob($direcotypath."/*.*");
        foreach ($files as $key => &$value) 
        {
                $value = str_replace( "..", $url, $value);
            }

            $final = array_merge($final,$files);

I have tried removing Thumbs.db using following code

foreach ($final as $key => &$value) 
    {     

              if($value == "Thumbs.db")
              {
                unset($final[$key]); 
              }
        }

Anyone know what is wrong with above code? I am still in learning process

Reading the documentation for glob more closely, you will see that you can set flags to filter the type of files that will be returned.

You can try something like:

$files = glob($direcotypath . "/*.{jpg,jpeg,gif,png,bmp}", GLOB_BRACE);
//                                 ^^^ Add more allowed extensions here.
