Is the __destruct method necessary for PHP?

Question

The manual said that

The destructor method will be called as soon as all references to a particular object are removed or when the object is explic

Answer 1

If you're using exceptions, you should try to follow RAII even with PHP. And you must use destructors for RAII. It was invented for C++ but the same logic works with PHP, too. Be warned that in some cases (e.g. fatal error or when exit() is called) PHP may end up calling the destructors in incorrect order which I consider a bug in PHP engine. For normal code and exceptions, the PHP engine seems to work as if it was C++ program.
