PHP4 static properties - PEAR vs my solution

[Hodicska Gergely <felho@xxxxxxxxxxxxxxxxx>]

Hi!


I had a little discussion on a forum topic about static class method and
properties. Somebody there pointed to the PEAR::getStaticProperty()
solution to emulate static properties in PHP4. I was not familiar with
it but its approach seems a little strange for me. It is not really more
than storing static properties in a global array.

I tried to make something better and come out with this solutions, which
I think is much more closer to the philosophy of a static property and
maybe is more elegant (of course this is subjective :)).

I'm curious about your opinion.

<?php
	class base
	{
		function &staticProperty($name, $value = null)
		{
			static $properties = array();

			if (func_num_args() == 2) {
				$properties[$name] = $value;
				return $properties[$name];
			} else {
				if (array_key_exists($name, $properties)) {
					return $properties[$name];
				} else {
					$php4_4suck = null;
					return $php4_4suck;
				}
			}
		}
	}


	class foo extends base
	{
	}

	class bar extends base
	{
	}


	foo::staticProperty('foo', 'foo');
	var_dump(bar::staticProperty('foo')); // NULL
	bar::staticProperty('foo', 'bar');
	var_dump(bar::staticProperty('foo')); // "bar"


	$foo = new foo();
	var_dump($foo->staticProperty('foo'));  // "foo"
	$bar = new bar();
	var_dump($bar->staticProperty('foo')); // "bar"


	$fooStaticProp =& foo::staticProperty('foo');
	$fooStaticProp = 'fooChanged';
	var_dump($foo->staticProperty('foo')); // "fooChanged"
?>
