PHP is interpreted on the server. If the server does not have PHP installed it cannot do this. While many *nix machines now come with it as a standard option, it’s still not going to be on your machine if you’re running Windows.

The only reason you'd need to download php is if you want to run a development server on your own machine.

PHP is not code that can be embedded in html files. PHP can return data with a content-type of text/html but so can any language.

PHP is a programming language designed to generate web content (images, xml, html). It is a parsed programming language. What happens when you go to a php page is the web server says to itself, "right, before handing them the data in this file, parse it with the php parser and then hand it over".

you said php is not code that can be embedded in html but what about this

<html>
<head>
<title>PHP Test</title>
</head>
<body>
<?php echo '<p>Hello World</p>'; ?>
</body>
</html>

You don't. But if you want to the code you've written, then you do need to.

where exactly do i find your web server's root directory?

Thanks

Create a file named hello.php and put it in your web server's root directory (DOCUMENT_ROOT) with the following content:

In debating terms, that's what we call a "argument by false comparison" fallacy.
Just because you can do something in PHP doesn't mean that that's all that PHP can do.

[PHP]
<?php
header ("Content-type: image/png");
$im = @imagecreatetruecolor(50, 100)
or die("Cannot Initialize new GD image stream");
$text_color = imagecolorallocate($im, 233, 14, 91);
imagestring($im, 1, 5, 5, "A Simple Text String", $text_color);
imagepng($im);
imagedestroy($im);
?>
[/PHP]

No html anywhere there.

Create a file named hello.php and put it in your web server's root directory (DOCUMENT_ROOT) with the following content:

It's probably something like "C:\Program Files\Apache Group\Apache2\htdocs"
or "/var/httpd/htdocs" if you're on *nix

You do have apache or IIS installed on your machine though?

If not, I recommend downloading http://apache2triad.net/

It will set up everything you need to beging writing php
