Remove characters from array output

Question

I have an array of images being displayed from a specific directory using the following code:

<?php 
    $dir = "img";
    $files = scandir($dir); 
    echo '<pre>', htmlspecialchars(print_r($files, true)), "</pre>\n";  
?>

The output of this code is as follows:

Array
(
    [0] => .
    [1] => ..
    [2] => image_1.png
    [3] => image_2.png
    [4] => image_3.png
)

What I would like to do is display the array of images as shown below thus removing [x] => for each image and also removing Array ( ).

image_1.png
image_2.png
image_3.png

Im not sure how to go about this. I have never really worked with arrays before therefore the only methods I can think of are preg_replace() or str_replace(), but honestly not sure where I would start.

Any help would be kindly appreciated.

Try:

echo '<pre>', htmlspecialchars(join("\n", $files)), "</pre>\n";

And quick way to remove . and ..: $files = array_diff( scandir($dir), array('.', '..') );

@Fabio: much appreciated. just to let you know, you forgot a single quote within the array ;)
