Question

I’ve already read a related topic here Function with same name but different signature in derived class.

I think the problem is the same but in my case it happens in PHP 5.4 (in PHP 5.3 works fine). The specific configuration is wamp 2.2, PHP 5.4.3.
I can’t see any errors in the logs and Chrome browser shows the following: “Error 101 (net::ERR_CONNECTION_RESET): The connection was reset.”

If I change the name of the function “init” in my example below, everything works fine. So I know what to do, but I would like to make sure that it is a bad practice in general for the same reasons explained in the related question. It would be helpful if PHP showed an error, I don’t know what is going on in the internals.

Any thoughts?

Thank you

class MyClass1 {

    private function init(){

    }
}

class MyClass2 extends MyClass1 {

    private function init($params) {

    }
}

$myinstance = new MyClass2();

I’ve just been looking up the PHP changelog and found something that might be relevant.

An item in the release notes for 5.4.4 reads as follows:

Fixed bug #61761 (‘Overriding’ a private static method with a different signature causes crash)

That sounds very much like what you’re seeing, especially since you specified that you’re using PHP 5.4.3.

As per my comment earlier, I would therefore suggest upgrading to a newer release of 5.4 (preferably the latest — currently 5.4.8).

Hope that helps.
