Retrieve static properties dynamically

[SiC_Goat]

Is there a way, without instantiating an object, to access a static property of a class based solely on a string?

 

Class MyClass
{
public static $MyProperty = 'MyValue';
}

$className = 'MyClass';

$classProp = /* magic */;

 

In need of 'magic'

the only way i can think of uses eval:

<?php
Class MyClass
{
   public static $MyProperty = 'MyValue';
}

$className = 'MyClass';
print eval('$classProp = '.$className.'::$MyProperty;');
print $classProp;
?>

 

you could write a static function to return the value:

<?php
Class MyClass
{
   public static $MyProperty = 'MyValue';
   public static function getProp ( ) {
    return self::$MyProperty;
   }
}

$className = 'MyClass';
$classProp = call_user_func(array($className,'getProp'));
print $classProp;
?>

Interesting idea, didn't know you could use call_user_func on static portions of an object that way. I'll probably just write a static property method that takes in a $name and return self::$name or something. Better than any non-solution I have so far.

otherwise take a look at PEAR.php which "emulates" static properties, their solution to cover the php4 disability on static properties, don't know if this is what you were looking for

As of 5.3.0 you should be able to use

 

$className::$MyProperty
