0 Never know the user's password, we must encrypt the user's password, and can not save the user's original password directly in the database. Do not limit the user password format. If the format is specified, it may be exploited and cracked by the attacker. Of course, we need to limit the minimum length of the password. It is recommended to use at least 8 bits. The longer the better.

For password security, developers need to:
1, absolutely can not know the user's password, we must encrypt the user's password, can not save the user's original password directly in the database.
2, do not limit the user password format, if the format is specified, it is likely to be exploited and cracked by the attacker, of course, we need to limit the minimum length of the password, it is recommended to at least 8 bits, the longer the better.
3, can not send the user password through the mailbox, when we develop the application to retrieve the password, the user password is not notified to the user by email, but the link to reset the password is sent to the user in the form of mail, let the user Go to reset the password.

0 The main purpose of this specification is to allow the log class library to log information in a simple and generic way by receiving a PsrLogLoggerInterface object. The framework and the CMS content management system can extend this interface if necessary, but this specification is required to ensure that the log interface can still be properly connected when using third-party class library files. This article develops a generic interface specification for the log class library.

The implementers in this article refer to the class libraries or frameworks that implement the LoggerInterface interface. Conversely, they are the users of LoggerInterface.

11 When you click on a page log-in or register button it will pop up a modal window which is a pop-up layer, we can easily switch on the popup login and registration form, a great convenience to users, without shutting down the floor to go click on to other operations, on many sites it has been widely used.

We will use examples to achieve this effect by using jQuery, CSS3 and HTML5 technologies.

8 We need to use to track user information Session and Cookie, such as user login authentication, user browsing history record store shopping cart data, user session valid time limit. Today we come to understand how to operate under PHP is the Session and Cookie.

PHP's $ _SESSION current user data can be stored, when the user visits WEB site, PHP will give users access to each create a session ID, the ID is a unique ID, saved on the client, and the user's session data is saved to the the service side, PHP can be stored for each different user information when the session expires, the user session information will be invalidated.

2 Sometimes we need to project a specific PHP information is encrypted, encrypted string that is generated by an encryption algorithm, the encrypted string can be decrypted by the decryption algorithm, to facilitate the decrypted program information is processed.

The most common applications in the user login, and some API data exchange scenarios.
I included some of the more classic PHP code encryption and decryption functions for everyone to share. Cryptographic principles generally through some encryption and decryption algorithms, the key is added to the algorithm, encryption and decryption finally get results.
