Trying to use GLOB function to create gallery.

[BluApple]

I'm stuck on this code:
 <div class="gallery"><?php $images = glob(FOLDER A); foreach ($images as $i) { printf("<img src='FOLDER A...'>"); } ?></div>

What needs to be replaced in "FOLDER A" do I need forward slashes? ("/")

<?php
$images = glob("path/to/folder a/*.*");
foreach ($images as $i)  {
	echo "<img src='$i'>";
}
