PHP code validation when refactoring -

-

As a developer used for stable typing, I usually tell the compiler that if the code is correct, logic Blame But when I have to do a PHP refactor, I know that it is right that my code is correct.

There always seems to be some strange reference to a law or a member who is broken and runtime. Even when limited refactoring support is used in Z Studio, it breaks in any way.

Due to the dynamic nature of language, I understand that this is a difficult problem. But is there a tool that is to verify the PHP code permanently, so that I can know that it's okay before the runtime? I do not want to see any more "undefined property" error messages.

Write a test for your code (), run a continuous integration server setup, UI test (). With enough testing, you will see your problems directly after a bad code. Just keep the test code coverage high.

This is a key point of unit tests - you can actually re-apply your code without breaking it, because you check all the functionality after every change.

The steps to parse the capture are: Open a connection at any time Loop a while Or start capturing using an event callback Parsing the raw packet for the type you want If you are reading .PPP dump files In addition to calling you an offline capture reader is almost the same, there is no need to select an interface, and you can set the majority There is no need to do the modes.
