CSS Positioning Example

drawmack

This is a little script I did up that is a basic example of css positioning. I know it looks a bit garish, but I wanted the divs to be easily visible.

It's also a palindrome checker.

wouldn't change a thing...but I have a few questions. Why did you put print_header(), print_css(), and print_footer() as functions? Why didn't you just put that code outside the php tags? Is it for security reasons?

nah just encapsulation, so when I do up another example page I have those things done already and they aren't mucking up my new code by being enmeshed.

The only thing I would suggest, for portability's sake, is to refrain from using <? ?> tags. I realize it's nice to use shortcuts like:

<?=$result?>

Instead, just use

<?php echo $result;?>

It really isn't that much extra typing, and it's a good habit to always use <?php ?>.

In what kind of situation would <?=$var?> ot work?

On my computer. I have short tags disabled so there is no conflict with this line of code:

<?xml version="1.0" encoding="UTF-8"?>

which is on the top line of a large number of my pages. 😉

but <?=$var?> isn't affected either way. I can understand why I should use <?php instead of <? but not <?php echo($var);?> instead of <?=$var?>

If short tags are disabled (so that you can use <?xml, for example), then <?=$var?> won't work. For that reason, you should always use <?php ?>.

For more information on this, visit the PHP Basic Syntax page.

Ohh :o I see now. I [edit]mis[/edit]understood how the parser worked with short tags disabled. However I do quite like the suggestions at the bottom of that link. If you're only going to be using the <?xml ?> tag once on the page then simply do <<? ?>?xml to trick the parser and then you can still use the short tags (I likeses my short tagses).
