Teach you to quickly implement PHP full-site permissions Validation _php Tutorial

PHP Full-Site Authorization code example:

2. < html>
4. < head>< title> e
6. < /title >
8. < /head >
10. < body>
12. < form action="login.php"
    method="POST" >

User:

1. < input type="text"
   name="username">
2. < br>

Password:

2. < input type="password"
   name="password">
4. < input type ="Submit"
   value = "OK" >
6. < input type ="Reset"
   value = "Cancel" >
8. < /form >
10. < /body >
12. < /html >
