Echo
-----------------------------------------------------------------------------------------------------------------------------


The "echo" function shows text a, the server does nothing  apart from generate a HTML file with the contents
YOU CAN STYLE THIS With CSS HTML OR JS 

E.G.: echo("<h1>Hello World!</h1>");

You can put HTML in a php file after ?> but it has to be before <?php 

E.G.
<?php echo("Some Random PHP code")>
        <p>lorem ipsum dolor sit amet</p>
        <?php }; ?>

You can break out of PHP mode at any time, just close with ?> and carry on, when you want to re-enter PHP mode use <?php

Get Request
-----------------------------------------------------------------------------------------------------------------------------

Get sends the server a request, and the user can see this request. 

E.G. ?i=~/  

? starts a Get request then you have a variable name (e.g. i ) then the variable is assigned to something (e.g. ~)

Code for a get request: 

<?php echo($_GET['hello']) ;?>

-----------------------------------------------------------------------------------------------------------------------------
Post request
-----------------------------------------------------------------------------------------------------------------------------

Post sends a request to the server, and the user cannot see it, it is usually used for usernames and passwords

E.G. <?php echo($_POST['hello']; ?>

-----------------------------------------------------------------------------------------------------------------------------
Important!
-----------------------------------------------------------------------------------------------------------------------------

PHP Requires ; after each line

-----------------------------------------------------------------------------------------------------------------------------
Request
-----------------------------------------------------------------------------------------------------------------------------

Get requests only listen to the results of a get request, Post request only listen to posts. $_REQUEST WILL LISTEN TO BOTH

E.G. <?php echo($_REQUEST['hello'])?>
