How to declare a static object in PHP?

Hi experts,

I am new to PHP, I have a HashMap class and want to declare as static
in my other class,

class web
{
public static $map = new HashMap();

}

somehow the compiler is complaining. It only allows me to do the
following:

class web
{
public static $map;

public __construct()
{
map = new HashMap();
}

}

but I don't want this, sorry for my stupid questions, i was coming
from C++ and Java background, so I am not quite familar with the
syntax in PHP.

Thanks alot

Best regards
ferdinand

just two easy changes:



class web
{
public static $map;

public function __construct()
{
self::$map = new HashMap();
}

}

- you have to access static object properties via self:: not via $this-
>
- and the construct needs the function keyword, like any other
function in php
