(PHP) Working with variables

In PHP there are no variable declarations, as shown below.

// not in PHP
int x = 0;
// this is how it is done in PHP
$x = 0;

Anytime you need to declare a variable you precede it with a $ (dollar sign). Once you have variables you need to do something with them. Often times you need to display the contents of a variable, as shown below.

<?php
   
   $good_morning = "Good morning, I hope you had a good nights rest!";
   // one way of displaying stuff
   print($good_morning);
   // another way of displaying stuff
   echo $good_morning;
?>

As you can see there are two ways to display stuff in PHP, print and echo.

Well it's as simple as that! Now get coding!
