Sorry, been doing heavy perl and haven't written any PHP in 3 years so a tad
rusty.
Can someone explain why the second expression in this code snippet evaluates
to 7 and not 8?
$a = (int) (0.1 +0.7);
echo $a\n;
$x = (int) ((0.1 + 0.7) * 10);
echo $x\n;
$y = (int) (8);
echo $y\n;

According to the PHP manual using the same expression, Never cast an
unknown fraction to integer, as this can sometimes lead to unexpected
results. My guess is that since it is an expression of floating
points, that the result is not quite 8 (for whatever reason).
Therefore, it is rounded

I think it's just the $query var not having the right number of quotes.
I added single quotes around the value.

Try Google. Type:

You might want to check,
"object-oriented"
as well...
I'm sure, you'll find helpful explanations...

Google didn't have much to offer.
But if I should also check 'object-oriented' then I believe it deals
with classes.
I thought it was something else.
Just trying to figure out if phpdoc is for me, which it seems like its
not :(
Thanks

Sorry 'bout that. Actually, if you have an idea of what OO
("object-oriented") is, I think I can say that "procedural" is just the
opposite of it.
I tried Google myself and this came out on top:
"Writing Procedural Code in Non-Procedural SQL"

It's the opposite of declarative code. Here's a page that briefly
explains the difference:
http://www.wdvl.com/Authoring/DB/SQL/BeginSQL/beginSQL2_1.html
and
Here is my stab at it. One person described it as the opposite of OO.
So something similar to -
?php
do_this() {
// do this code
}
do_that() {
// do that code
}
if (isset( $_GET['foo'] )) {
do_this();
} else {
do_that();
}
?
would be considered procedural code.
If Im wrong I

Some arrays use the format:
$row-data
while some use:
$row['data']
What is the terminology of these types so I sound like I know what I'm talking about.
Also, when and how do each come about?
