Can I overload methods in PHP?

Question

Example:

I want to have two different constructors, and I don\'t want to use func_get_arg(), because then it\'s invisible what args are possible.

Is it legal

Answer 1

No, but you can do this:

class MyClass {
    public function __construct($arg = null) {
        if(is_array($arg)) {
            // do something with the array
        } else {
            // do something else
        }
    }
}

In PHP, a function can receive any number of arguments, and they don't have to be defined if you give them a default value. This is how you can 'fake' function overloading and allow access to functions with different arguments.
