Question
When accessing a class constant I see that I can use a variable for the class name, e.g. $classname::CONST_VALUE
.
What if I want to use a variable for the constant name, e.g. self::$constant
. This does not seem to work. Is there a workaround?
Solution
$variable = $classname.'::'.$constant;
constant($variable);
See the docs: http://php.net/constant
