function getArtefacts($searchDir, $ear = array(), $invert = false, $type = 3){
    $far = array();
    if($handle = opendir($searchDir)){
        while(false !== ($file = readdir($handle))){
            $temp = false;
            foreach($ear as $value){
                $temp |= preg_match('/^' . $value . '$/iD', $file);
                if($temp != false) break;
            }
            if($invert)    $temp = !$temp;
            $temp |= preg_match('/^\.{1,2}$/iD', $file);
            if(!$temp){
                switch($type){
                    default:
                    array_push($far, $file);
                    break;
                    case 2:
                    if(is_dir($searchDir . '/' . $file)) array_push($far, $file);
                    break;
                    case 1:
                    if(is_file($searchDir . '/' . $file)) array_push($far, $file);

Instructions: string $dir: directory you wish to search
array $ear: an array of regular expressions with what you wish to include or exclude from the results
boolean $invert: whether you wish to include or exclude TRUE = include, FALSE = exclude
integer $type: a flag setting which will include files or directories inclusively or exclusively, FILE_FLAG for files, DIR_FLAG for directories, and FILE_FLAG | DIR_FLAG for both
RETURNS
array $far: an array with files/directories

Examples:
// prints all the folders in the directory
print_r('.', getArtefacts(array('.*\.[a-z0-9]{3,4}')));
print_r(getArtefacts('.', array(), false, DIR_FLAG));

// prints all the files in the directory
print_r('.', getArtefacts(array('.*\.[a-z0-9]{3,4}'), true));
print_r(getArtefacts('.', array(), false, FILE_FLAG));

// prints all .htm or .html files in the directory
print_r('.', getArtefacts(array('.*\.html*'), true));

// prints all files that don't end in .htm or .html
print_r('.', getArtefacts(array('.*\.html*'), false, FILE_FLAG));
