Excluding hidden files

[neridaj]

Hello,

I'm having problems figuring out how to exclude hidden files when building an image array. I'm using a regex to validate the image, should I use another regex for hidden files instead of strtok()?

function get_after_thumbs()
{
	$dir = get_dir();
	$afterdir = $dir . 'after/thumbs/';
	$files = scandir($afterdir);
	foreach($files as $value) {
		// check for image files
		if(valid_image_file($value))
			if(!strtok($value, '._'))
			// build image array
			$imgarr[] = $value;
	}
	$count = count($imgarr);
	for ($i=0; $i<$count; $i++) {
		echo '<img class="floatright" src="' . $dir . 'after/thumbs/' . $imgarr[$i] . '" width="25" height="25" alt="09 285" />';
	}
	var_dump($imgarr);
}

Thanks,

Jason
