Dumping all files in folder into one and displaying them - php

Question

I need to take all the files in the folder where the PHP file is, dump them together, and echo them. What is the simplest way to do it?
For example, I have the following files:
ILikeFish.txt
I like fish please bring me fish!
Well that's enough don't bring me anymore.
ILikePotatos.js
var Potatos = {yummy:true, amount:5323.6}
function potatoFunc(stuff) {
while (stuff=="cool") moreStuff();
}

Well, I want the output to be:
(.txt ignored)
var Potatos = {yummy:true, amount:5323.6}
function potatoFunc(stuff) {
while (stuff=="cool") moreStuff();
}
(Picture ignored)
How can I do it? Thanks for answering!
Also, I'm VERY basic in PHP and I know nothing, so please forgive me if this question is super dumb. Also, I AM aware of this question, but it doesn't answer how to do it!
Also, my final goal is to include all my libraries and comments using one line of
<script src="http://MySite/AllJsses.php"></script>
And again, Thanks for taking the time and answering!!!

Answer 1

Okay, after playing a little with google, w3schools and my genius brain I came up with the following:
<?php
$files = glob("*.js");
for ($i = 0; $i < count($files); $i++) {
echo file_get_contents($files[$i]);
}
?>
Thanks to myself and to some guy on other forums for answering this question! :D
Also, if any of you find any errors / performance issues / anything, please comment, because otherwise host gonna kill me. Thank you!
