Html is static.

Php is dynamic.

They are very different.

Php can output html if you want.

code:

<?php
header("Content-type: text/html\n\n");
echo "<html><body>Php outputting html.</body></html>";
?>

which would output this:

code:

<html><body>Php outputting html.</body></html>

Php can make things like simple counters, login programs, and anything to shopping carts, or as homer said games.

think of it this way....

in programming there are three main phases... input, processing, output
HTML can only do the input and output phases... PHP pretty much adds the processing stage to it

it can be simpler than that, you dont really need the header line..

well u could add html and javascript together to make it dynamic...couldn't u?

Amailer · **Posted:** Sun Jun 22, 2003 7:31 pm

you could, but its just extra. Really not needed Smile

Now things that might be needed sometimes [[ well... everything is needed at some point Smile

]] is like this

code:

<?
//A web site...
$location = "http://mysite.com";

//rest of the code :)
if($location == "http://mysite.com") {
header("Location: $location"); /* redirection, sends the user to the $location */
} else {
echo "$location was incorrect!";
}
?>

you might be referring to dHTML which is just javascript and CSS used together to make dynamic stuff happen in real time.

as far as making PHP dynamic... it's dynamic at the time the page is loaded... so like you could have some variable to determine whether a bit of HTML is used

a main thing you notice when viewing a PHP page is that if you view the source, you don't see any PHP code...this is because any PHP code is exectuded when the page is loaded and then the HTML displayed based on what the PHP code did.... hence why it is called hypertext preprocessor

Well, the only problem with php is that its only for the web Sad

, BUT STILL INSTED of that, its the best one [[ i ever ]] used to make my web sites, i mean its amazing, and its so easy.

octopi · **Posted:** Thu Jun 26, 2003 10:29 pm

php is not only for the web.

I have it set up on my server so I can access it in something similar to a dos window.

Although, you are correct, it is AIM'ed mainly for web development usages.
