Hi guys!
I've read a lot about PHP5 standards, but I was wondering if there were any - special - OOP standard in PHP5?
Btw, what is the "right" why to declare variables in the start of a class? I've seen a guy doing this.
Code:
public $name = "John Doe";
Step away from public... and tell me if that's a way to do it or a wrong way to do it?
I like doing this (mostly because I've seen a lot people are doing it like this).
Code:
public var $name = "John Doe";
Any links with PHP5 OOP standards would be nice! Thanks!

var is just to tell PHP that this is a variable (more accurately a property) of your class.
public/private/protevted tell PHP 5 that it is a special kind of var. This means you dont need to say that it is a "public variable" and then also mention it is a "variable" as you are repeating yourself.

I know what public, private and protected does. Just thought it was better not to write "var". Oh well, I like it that way and I'll keep it that way, I think it's more organized and well structured.

Public stuff : Can be used outside the class itself
Code:
<?php
class class_1 {
public var $foo = "foo";
}
$class = new class_1();
echo $class->foo; // Prints foo
?>
Private stuff : Can only be used in the class itself
Code:
<?php
class class_1 {
private var $foo = "foo";
}
$class = new class_1();
echo $class->foo; // Returns an error
?>
Protected : Can be used outside the class, but with limitations
Code:
<?php
class class_1 {
private var $foo = "foo";
}
// This will not work
$class = new chass_1();
echo $class->foo;
// However this will
class class_2 extends class_1 {
function foo() {
echo $this->foo; // Prints foo
}
}
?>

var is kept in php5 and php6 as an alias for public.

I've never seen anyone write public/protected/private and var
I stick to the PHP5 syntax for declaring variables/functioncs, cause I prefer it, and force of habit (damn Java)

I actually never use it either, but it doesn't really make a difference

?
I would highly suggest that for the sake of proper OOP design...

Dam1an meant to say he never saw the combination of both public/private/protected
AND var.
In PHP4 you write:
in PHP5 you write:
Using BOTH is just plain weird:

It makes little or no difference to the way it's parsed, so it's purely for aesthetics. You can easily tell what follows a public/private/protected keyword by the prefix. If it starts with a '$' then you know it's a variable, otherwise it's a method. That's enough for me, so I don't bother with using var.
