This question already has an answer here:
When trying to boost code quality, I frequently encounter errors like "The use of function file_exists() is forbidden" when trying to use PHP file functions. This for instance happens with the Magento ECG coding standard and also with the Magicento plugin for PhpStorm. However, I'm kind of lost on what I should use instead. The ZF-1 documentation is not listing any wrapper like
Zend_File so there must be something I'm overlooking ...
Anyone has an idea?
