What's a variable and what can you do with it?

First, we already saw we can store something from readLine() in a variable:

<?php

	$n = readLine("What is your name? ");
	$f = readLine("What is your favourite fruit? ");

	echo "Hello, Mr. ";
	echo $n . "!\n";
	echo "Do you want to eat " . $f . "?\n";

?>

We can also store numbers.

<?php

	$a = 5172;
	$b = 171;

	echo $a * $b;

	echo "\n";
?>
