My php process some things but not all it seems. I've got it to work with apache 2.0.58 (i know its not the latest but whatever). I created a file with the phpinfo() command and when I went to the page at http://localhost/phpinfo.php I was able to see the information displayed. When I use this code:

<html>
<head>
<title>A Php script including HTML</title>
</head>
<body>http://www.mozilla.com/products/firefox/central.html
Getting Started

<?php
echo "Hello World!";
?>

</body>
</html>

It works I see Hello World, but when I use this code:

<?php
$testing; //declare without assigning
echo gettype($testing); // null
echo " ";
$testing = 5;
echo gettype($testing); // integer
echo " ";
$testing = "five";
echo gettype($testing); // string
echo " ";
$testing = 5.024;
echo gettype($testing); //double
echo " ";'
$testing = true;
echo gettype($testing); // boolean
echo " ";
$testing = array('apple', 'orange', 'pear');
echo gettype($testing); //array
echo " ";
?>

I should see

Null
integer
string
double
boolean
array

on the screen but all I get is a blank screen. Why is this? BTW I'm getting this code from a book a bought to learn apache php and mysql, also I don't have mysql installed.

Edited: Code corrected. Series of typos.

um, shouldn't the php closing ?> be right after the php snippet?

Edit: what PHP version are you using?

<?php
$testing; //declare without assigning
echo gettype($testing); // null
?>

If there is an error in any programing the easiest way to debug it is to break it into smaller pieces. try adding more code until it doesn't work anymore and start from there.

Edit: spelling

I broke it into smaller pieces and the whole thing worked and I didn't change anything, why is that? The original btw still doesn't work but the new one does and its exactly the same code. I'm confused.

I don't know. Although I typicaly like to know why something works before using it. I would say in this situation that if It works, go with it.
