php - Access static object property through variable name

Question

I know its possible to access an object property/method using a variable as its name

ex.:

$propName = 'something';
$something = $object->$propName;

Is it possible to do the same w/ constants or static properties?

I've tried:

$constName = 'MY_CONST';

MyCLass::{$constName};

and

$obj::{$constName};

But nothing seems to work and I couldn't find it anywhere.

Answer 1

Use: Class::$$constName, this is similar to normal variable variables.

Demo:

<?php    
class MyClass {
    public static $var = 'A';
}
$name = 'var';
echo MyClass::$$name; // echoes 'A'

Constants can be access with the constant function:

constant('MyClass::'.$constantName)
