php封装的用户登陆验证的类,实现了用户登陆的常用功能,包含cookie和session的设置,php用于登陆验证的类,对此感兴趣的朋友,看看idc笔记做的技术笔记。经测试代码如下:1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 | <code class = "php" > /** * 用户登陆验证的类 * * @param * @arrange (www.idcnote.com) **/ class Auth { var $user_id ; var $username ; var $password ; var $ok ; var $salt = "34asdf34" ; var $domain = ".domain.com" ; function Auth() { global $db ; $this ->user_id = 0; $this ->username = "Guest" ; $this ->ok = false; if (! $this ->check_session()) $this ->check_cookie(); return $this ->ok; } function check_session() { if (! empty ( $_SESSION [ 'auth_username' ]) && ! empty ( $_SESSION [ 'auth_password' ])) return $this ->check( $_SESSION [ 'auth_username' ], $_SESSION [ 'auth_password' ]); else return false; } function check_cookie() { if (! empty ( $_COOKIE [ 'auth_username' ]) && ! empty ( $_COOKIE [ 'auth_password' ])) return $this ->check( $_COOKIE [ 'auth_username' ], $_COOKIE [ 'auth_password' ]); else return false; } function login( $username , $password ) { global $db ; $db ->query( "SELECT user_id FROM users WHERE username = '$username' AND password = '$password'" ); if (mysql_num_rows( $db ->result) == 1) { $this ->user_id = mysql_result( $db ->result, 0, 0); $this ->username = $username ; $this ->ok = true; $_SESSION [ 'auth_username' ] = $username ; $_SESSION [ 'auth_password' ] = md5( $password . $this ->salt); setcookie( "auth_username" , $username , time()+60*60*24*30, "/" , $this ->domain); setcookie( "auth_password" , md5( $password . $this ->salt), time()+60*60*24*30, "/" , $this ->domain); return true; } return false; } function check( $username , $password ) { global $db ; $db ->query( "SELECT user_id, password FROM users WHERE username = '$username'" ); if (mysql_num_rows( $db ->result) == 1) { $db_password = mysql_result( $db ->result, 0, 1); if (md5( $db_password . $this ->salt) == $password ) { $this ->user_id = mysql_result( $db ->result, 0, 0); $this ->username = $username ; $this ->ok = true; return true; } } return false; } function logout() { $this ->user_id = 0; $this ->username = "Guest" ; $this ->ok = false; $_SESSION [ 'auth_username' ] = "" ; $_SESSION [ 'auth_password' ] = "" ; setcookie( "auth_username" , "" , time() - 3600, "/" , $this ->domain); setcookie( "auth_password" , "" , time() - 3600, "/" , $this ->domain); } } /*** 来自php教程(www.idcnote.com) ***/ </code> |
