First of all, read the source for Cakephp and PHP.
It is necessary to work on both 2 and 3 systems.
I'm following the authentication part (Auth component) by opening a text file with the current source.
Is there a de facto standard environment for developing Cakephp?
The environment is xampp on Windows.
I asked a question here because there are no people who can ask questions.
I am sorry if it is a misguided question, but thank you.
