Variables- Quick General Question...

madcat

Just to clear up confusion about register globals. When using variables in a script...we can use:

$local = $whatever + $whenever;

but, when calling variables from other scripts we have to use either $_post[] or $get[] right?

You don't have to use the second form all the time, just when pulling variables from separate pages.

If you are trying to pass variables form one page to another using links or forms, you need to use: $GET or $POST, assuming that REGISTER GLOBALS is off.

On the same page you do not need to use that.

So:
$var1 = "Dylan";
print($var1);

will print:
Dylan

But if I wanted to pass that to another page in a URL, like this:

http://www.somesite.com/page.php?name=Dylan

and I wanted to use it, I would need to do this:

$name = $_GET['name'];

Help?

Yeah, that sure did - thank you.

Ok, and in the same vein-

Is it necessary to include a <doctype> and header HTML tags like <html><head><title>...with every .php page except for php includes because they are already going into .html templates that have the header info?

Or is that information unnecessary for .php pages?

jburfield

It depends on what you are doing with the pages...if it is a .php page that includes nothing but functions, then no, y ou do not need the <head>, etc tags...

However, if you plan to show that page to a browser, then yes, you need the tags.
