Ob_start, "protected" obHandler method, nod detecting $this->geMe () kind of error! View as Markdown

Actually it's not when you want to separate Output Buffering from
ErrorHandling. :) . and YES, you can access "obHandler" when it is
protected, because you extends the abstract base class, but it fails
miserably on the "$this->getMe ()" error type.

If the "obHandler" method is "public" the "$this->getMe ()" from GLOBAL
context will get detected. If "protected", the obHandler method, for the
"$this->getMe ()" error isn't even called.

   I know this because when it's public I can generate the error and

"error_log ()" it, but when it is "protected", the error_log isn't even
called inside the obHandler method, so the obHandler method isn't even
called.

Well, ob_start can't access a protected method...
Think like, if u can't do ErrorH::SomeMethod, u can't do ob_start(
ErrorH::SomeMethod ).

PS: U really need to call a method of a class that extend your actual class?
It's seems like a bit circular :S

Yes, that's the "so-called bug" I'm talking about. Having the obHandler
marked as "protected" makes "$this->getMe ()" kind of errors, from GLOBAL
context undetectable, while Parse/Notice/Warning errors are stil there,
even
if the "$this->getMe ()" error is marked as "Fatal Error:". Here: Fatal
error: Using $this when not in object context in
/var/www/localhost/htdocs/dev/ALFA/index.php on line 26 (this is when
obHandler = public).

A blank page = when obHandler = protected, but Parse/Notice/any other kind
of errors are still detected. :)

Hello guys,

           We have too clases:

•      Abstract class OutputBuffering
  

•      Class ErrorHandler extends OutputBuffering, implements
  

obHandler

as a "protected" method. I can detect: set_error_handler errors, through
a
specific error handler (and obError method - I can detect any
notice/warning/fatal) and also "Parse errors" in obHandler, through
"parsing" error_prepend/error_append strings in the Output Buffer
string.

When the obHandler methos is "protected", the "$this->getMe ()" from
GLOBAL
context cannot be detected. When the method is "public", the detection
goes
as usual. The MANUAL Page on "ob_start" doesn't say anything about
declaring
the method "public". What if I want the "obHandler" method to not be
accessible by the developer, but only by inheriting objects?!

Thanks for any feedback.

Regards,

Catalin Z. Alexandru

Did you tried protected? I'm not really good with this things, but a
protected method can be inherited but not acessed outside the class ;)
