 New Comment:

Additionally to what laruence said, one should also point out that __construct is quite commonly
called directly in the form of parent::__construct().

PHP's __construct, actually, is not creating object, it decorate the object after 
it was created.

so,  even you directly call to $obj->__construct, then no new instance was create.

so a workaround is you can exam some property you set to see whether that is a 
double constructing or not.


thanks

Description:
------------
It is possible to directly call the magic method "__construct". This should NOT be
possible, since one cannot create immutable objects with the current behaviour.

In addition, a direct call to the magic method "__clone" is not possible and raises an
"\E_FATAL". Both magic methods deal with object creation, so the behaviour is inconsistent
between them.

I am using "php-5.4.13-nts-Win32-VC9-x86" on Microsoft Windows Version 6.2.9 x64(Windows 8
64 bit).

Test script:
---------------
https://gist.github.com/FlorianWolters/5195734

Expected result:
----------------
The method call:

$example->__construct();

should raise an "\E_FATAL" with the following message:

"Cannot call __construct() method on objects - use 'new <Class>' instead in
[...] on line 21"
