How to check file types after reading the directory

[htiek]

I can t seem to figure this out

Im reading the directory like this

$directorylist [0];
$curent_dir = “path to directory";
$dir = opendir($curent_dir);
$count = 0;

while ($file = readdir($dir)){
	$directorylist [$count] = $file;
	$count = $count + 1;
}

I want to only read in a certain file type (.gif for example or .tga). How can I ensure only these files make it into the array directorylist.

Thanks

// Accepted file extensions
$accepted_types = array("tga","gif");

$directorylist[0];
$curent_dir = “path_to_directory";

$dir = opendir($curent_dir);
$count = 0;

while ($file = readdir($dir)){
    // See if the file extension is allowed
    if(in_array(substr($file,-3),$accepted_types)) {
        $directorylist[$count] = $file;
        $count = $count + 1;
    }
}

Edit: Whoa not thinking today.
