Can someone please explain all the 'scopes' and what they do, the website i'm using at is using language which I have never heard of before, w3schools so could anyone tell me what they do? oh, and what 'function myTest()' does.

'function myTest()' is just a made up function you typed up, or read from the tutorial, it'll have an action in-side it deeper in what you're reading, or once you have coded it.

myTest() executes what's within the myTest() function when called.

For example:

<?php
 
function myTest() {
 
    echo 'Hello world.';
 
}

Now when you execute the function my calling it else where in the code, it will out put the following:

Hello world.

Example:

<b><?php myTest(); ?></b>

That outputs:

Hello world.

Ah, so now - whenever myTest is said in the script, it will say hello world?

Yes, as long has you have parentheses and a semicolon an the end, just like RastaLulz did.

Also, if you are making a class, you would have to call the function, and require the class' file. The only difference is with a class, you have to do something like this:

$class->functionName();

where without a class, you don't need the variable, you can do:

functionName();

I hope I helped
