Does anyone please know of a way to access static methods of a class, when
the name of that class is held in a variable?
I have several classes (PHP5) which all have identically named methods and
members.
I want to pass the name of one of the classes to an included file which
does some standard operations using those methods and members. (So several
different programs can include that file, each passing a different class
name.)
I am doing this by putting the name of one of the classes in a variable
which is passed to the included file. So for example:
$classname = 'Foo';
$instance = new $classname();
$instance->do_method($id);
That all works fine.
But how do I access static methods and constant members of the class?
$classname::static_method()
and
$classname::MY_CONSTANT
both give errors. Every variation I've tried gives an error. Is there
something I'm missing in the syntax which will let me do this? Or maybe a
different method of passing the name, or of approaching the while thing?
I've found two ways of kludgeing round the problem. One is to use eval()
round everything, and the other (untested) is to use Reflection. But
surely there's a less messy way?
