PHP login, registration and password modification function analysis, php password Modification

This example describes how to implement the login, registration, and password modification functions in PHP. We will share this with you for your reference. The details are as follows:

Here we will introduce the page layout and function implementation of registration, logon, and password change:

1. log on

2. forgot password

3. Free Registration

Page Layout:

<Div id = "views" class = "views"> <div id = "view-login" class = "page-view-login active"> <present name = "wxuser "> <div id =" wxuser "class =" form-group text-center "> <div>  </div>

Summary:
1. Text message verification is used for registration and password modification.
2. For security, front-end ajax verification. The backend is also verified.
3. The process is reasonable and easy to switch.
4. Comprehensive Functions, logon, registration, and password modification.
