I want to learn it, ABSOLUTELY, but I spent a whole hour today trying to figure it out when it's for a few simple lines of code.

Well, I'll take the comparison chart and try again. :\

I had made a little progress but this chart does show me a cleaner way of doing it that I wasn't aware of. :\ Hrrrm...

I do have one question, though, and this probably seems very newbish. What is the actual explanation in simple terms for ->. I've heard "object->property" but I'm not sure I fully understand. :\ We were not introduced to it in our classes.

"object->property" is the simplest description of the object operator in PHP.

You can sorta (sorta) think of it like the slashes in a URL, if that helps. Objects can have other objects as properties and you'll often see that operator chained like object->object->....

Ironically, Rey... that actually helped. >_>; That triggered a memory of my teacher saying that in class. Got out my old notes and figured it out. Objects are basically a clump of functions and shit like that.

The precise definition of an object (in an object-oriented programming, or OOP, context) varies between languages, but the general notion of an object in most languages that have some kind of OO aspect to them is that of a container that bundles some variables and the functions (referred to as methods in PHP when part of an object) that operate on them.

In your snippet, $date is an object that is an instance of the DateTime class. Classes are essentially blueprints for making usable objects with the properties and behaviours described by that class.

$date->format(...) in your snippet is a reference to the format() method defined in the DateTime class.

The official Java tutorials site has a fairly casual and approachable , which applies to PHP as well.

The problem you're having with the second connection isn't with classes, but functions.

O_O Aw! GLOBAL!

^_^ FIXED!


*mutters* <_<; That wasn't very fun... I was so sure there was something more complicated I was doing wrong.

Anywho, though, considering you didn't say anything :3 I'm assuming I'm using the -> stuff correctly and the class is set up correctly (now that $link is set to GLOBAL)?

(BTW, XD I liked the tutorial hint treatment.)

^_^ Oh, by the way - in case I haven't said it recently, negzee. THANK YOU SO MUCH FOR THE HELP! I appreciate your teaching me like this. <_<; Sorry for being such a n00b sometimes. And everyone else, too!

You're welcome.

There's no mysqli equivalent to mysql_result(). The way you're doing it is perfectly fine, although I wouldn't bother to name the value of count(*), and would simply fetch_array() instead of fetch_assoc().

As for mysqli_result::free() and mysqli::close(), you generally don't try to test if they worked.

Could it be that a different ISP has different versions of essential software installed?
