我如何在php中创建一个名为“Authenticator”的类来接受文件

Question

how do i Create a class called "Authenticator", with a constructor “Authenticator($filename)” that takes the filename of a password file as an argument.

Answer 1

Class constructors in PHP are created like this:

class Authenticator {
    function __construct($filename) {
        // do stuff with the filename here
    }
}

Then used like:

$auth = new Authenticator('filenameGoesHere');
