[PHP-DEV] Required __construct call in SplFileObject

[Christoph Rosse]

Hi,

I'm just curious is there a reason why SplFileObject requires a call to 
parent::__construct()
if I override the class? Someone on my twitter feed mentioned it because 
he tried to create a Mock-Object.


The following code gives me:
PHP Fatal error:  Uncaught exception 'LogicException' with message 'The 
parent constructor was not called: the object is in an invalid state


?php

class cls1 extends \SplFileObject
{
public function __construct()
{

}


public function fpassthru()
{
}
}
$cl = new cls1();
$cl-fpassthru();

The way this class is designed, it needs to take the file name via the
constructor as an initiation point.

if you try to call a method of this class without initiation occurring it
will throw an exception.

this is why you must instantiate the SplFileObject's __construct() method
to start the initiation.

Hope this helps.

Maybe this should be mentioned in the docs.
I know how to use http://edit.php.net but where do I put this kind of 
information?
In the __construct method documentation 
http://php.net/manual/en/splfileobject.construct.php or somewhere else?

You could put it either inside introduction or just below it, in the 'info'
style, just to inform people they must call parent::__construct() upon
instantiation of their object in order to use this.
