PHP5 and static functions/vars

Hi,
I need to add a string to a class var, but it doesn´t work though I read it
is a new feature in PHP5.
This is my code:

class Huh{
static $message;

public static function addMessage($message){
Huh::message += $message."<BR>\n";
}
}

What´s wrong?

I am not sure what you are trying to achieve with this. Are you trying to
modify a class definition?

You can't make non-instance calls like that.

I am guessing what you want to do is use object's method to change/update
the property; if so, you need to create an instance of the object. And, in
that case, don't define those methods and properties as static.

You don't need to create an instance of an object ... the following works
for me (tested right now ;):

<?php

class Test {

static $testingval;

public static function setVal($val){

test::$testingval += $val;
echo "val: " . test::$testingval . "<BR>";

}

}

test::setVal(1);
test::setVal(4);
test::setVal(8);

?>

with results:

val: 1
val: 5
val: 13

on `official` PHP5b1

regards!

Simple syntax problem:

Huh::$message += $message;

Shouldn't you use a "." as a string concatenation operator?
