There are numerous variations to loop through a list of files in a directory in PHP. Here are a couple of simple ways:

Variation 1:

$folder = dir("/path/to/folder");
while($folderEntry = $folder->read()) {
    // $folderEntry is the resource. You can now check against it.
}

Variation 2:

if ($handle = opendir("/path/to/folder")) {
    while (false !== ($file = readdir($handle))) {
        // $file is the resource
    }
}

Both use assignment in a while loop to not only get the resource but terminate looping through your results. Variation 2 includes a condition to see if there were issues while openning the directory. You should consider how you will deal with these in your code.
