Re: [PHP] Using a HTML button
JAVASCRIPT VERSION
mytitle
function multiply(x){
var myresult = 2 * x;
document.write(myresult);
}
PHP VERSION
mytitle
if($mybutton){
$myresult = 2 * $mybutton;
print $myresult;
}else{
print "Click the button to see what 2 mulitplied by 5 is!";
}
You can do it either way, don't take my code at face "value" (sorry,
couldn't resist) I haven't tested it, but it should be enough to get you
going. I would suggest that you use the PHP version, that way you don't
have to worry about cross browser JavaScript compatibility.

Re: [PHP] Using a HTML button
PHP is entirely server-based. So when you load this page into your
browser, all of the PHP is being parsed BEFORE it ever loads into the
browser. So the function will be executed even before the page loads.
Do it in JavaScript if you want it to be done in the browser. What you
have written down will show up in the source code of your browser as:
(or something like that).
PHP runs entirely on the
server. Server! Server! Server! Server! Honest, I promise that it
doesn't get interpreted by the browser. If you have any doubts, try
writing a PHP script, reading it in your browser, and then viewing the
source code to see what gets rendered.
For browser-side scripting, I suggest you pick up a book on JavaScript
programming. Nothing you do in PHP will ever be interpreted by a browser.

What value is it returning 5, or 10?
