Class (not object) methods and variables

[Anon]

Does PHP support class methods or variable?

Something like:

<?
include ('myClass.php');

$obj1 = new myClass;
$obj2 = new myClass;

[...]

$count = myClass->object_count();

?>

I found an old message on the general php list dated sometime in 1999 that said this is not possible. I'm hoping with php4 that this is no longer the case?

Shocking news: PHP has a manual!

nope, no static variables 🙁

you have to use globals and do like

function ObjectConstructor() {

global $someVar;
$someVar++;
}

function objectCount() {

global $someVar;
return $someVar;

}

You can use :: to call methods statically, but since you can't have class variables, you can only use them like normal methods

class A {

function display() { echo 'hi'; }

}

A::display();

That's all you can do to my knowledge.

Hope that helps.

Thanks for the info. Globals it is, then. :-/

I've only been working in php for a couple weeks, and am pleased (and surprised!) that this support forum produced a relevent response to my question in a matter of hours. Early on a sunday morning, no less.

That speaks well of the php community. Thanks for that too.

Yep. Some of the 'biggest' pains most programmers that use PHP frequently are

1. no static memebers
2. no multiple inheritance
3. no """ for quoting strings with more than 1 line
4. object instantiation speed
5. requires/includes should be used in the section of code when needed rather than at the top of the file. (Note: It's okay to put at the top, but since php scans the code every hit, it makes pages go slower)

plus a few other things.
