How do I access a static variable when I do not know the name of the

I have the following example PHP:
ket% cat test.php
<?php
class Test
{
public static
$STEPS = array(
'foo',
'bar');
}
$className = 'Test';
var_dump($className::$STEPS);
ket%
Unfortunately when I run it I get:
ket% php test.php
Parse error: syntax error, unexpected T_PAAMAYIM_NEKUDOTAYIM
in /home/jablko/trash/test.php on line 13
ket%
I can call a static function using call_user_func(array($className,
'functionName')), and I can access a class constant using
constant($className.'::CONSTANT_NAME'). How do I access a static
variable?
this does beg the question why don't you know the classname at runtime..
seems to be a slight design flaw and may make sense for you to post the
full problem (you must have chosen to implement this for a reason..)
if you really really must do this, you'd be best off to have a look at
reflection..
<?php
class TestClass {
public static $STEPS = array( 'foo' , 'bar' );
}
$testClass = new TestClass;
$rTestClass = new ReflectionClass( get_class($testClass) );
print_r( $rTestClass->getStaticPropertyValue('STEPS') );
?>
