If you drop the &&, yes. If the IF-statement passes, everything between 
the curly brackets {} will be executed. So, yes, you could do that.

Personally, I'd recommend using a switch[1] in this case, though. You 
can read more about it on the PHP.net website, but here's the basics in 
your situation:

    case 'cool-site.php':
        $parent = 'cool-site.php';
        $thisPage = 'Cool Site';
        $PageHeader = 'Cool Site Header Text Here';

Repeat everything from case to break for each page. Just keep it within 
the curly brackets.

Close. If you open a string with a double quote, you have to close it 
with a double quote as well. The same with single quotes. As for 
escaping, that would depend on your choice for opening and closing the 
string. If you open and close with a double quote, you'll need to escape 
double quotes inside the string. If you open and close with a single 
quote, you'll need to escape single quotes. Example:

$PageHeader = "Cool Site's Header Text Here";
$PageHeader = 'Cool Site\'s Header Text Here';

$PageHeader = "Cool Site\'s Header Text Here";
$PageHeader = 'Cool Site's Header Text Here';

The first incorrect option will simply output the \ as well. The second 
one will throw an error, because, as far as PHP is concerned, the string 
is "Cool Site", and where there's "s Header Text Here" it will expect a

No problem. I would recommend staying clear of the short open tags, 
though. Try to use "<?php" instead of just "<?". For one thing, PHP 6 
will no longer support the short form (can't find the source at the 
moment). For another, not all webservers running PHP 4 or 5 have the 
option enabled. It can also be confusing with XML-declarations, as they 
have the form of "<?xml".

Good luck, and feel free to ask away, on or off list :)
