My programming experience is clearly modest, and I have little formal training. I suspect one or two options w...

Hi everyone, Ive looked and tried but I can't find an answer. In PHP, is it possible to call a class' member function (when that class requires a constructor to receive parameters) without instantiating it as an object? A code example (which gives errors): <?php class Test { private $end=""; function __construct($value) {...
