In a image gallery I have to class'es:
class GPicFilePicture extends GPicFileType
class GPicFileMovie extends GPicFileType
both of them are based on:
abstract class GPicFileType
In my code I need to create a new GPicFilePicture. To avoid duplicated
code I've create a wrapper class:
class GPicFile
that does something like this:
if (fileextension == "jpg")
return new GPicFilePicture();
else
return new GPicFileMovie();
so my PHP code looks like:
$file = new GPicFile($filename);
getFileDate() is implemented in both GPicFilePicture and GPicFileMovie.
Now I try to do:
$file->getFileDate();
I get an error saying:
Call to undefined method GPicFile::getFileDate()
Where am I going wrong?
My way for doing this summed up by the Factory Pattern described on this
