.htpasswd 文件示例: user1:{SHA}kGPaD671VNU0OU5lqLiN/h6Q6ac= user2:{SHA}npMqPEX3kPQTo+x/+ZckHDrIcQI= user3:{SHA}q1Fh2LTUjjkncp11m0M9WUH5Zrw= 复制代码 代码如下: class Htpasswd { private $file = ""; private $salt = "AynlJ2H.74VEfI^BZElc-Vb6G0ezE9a55-Wj"; private function write($pairs = array()) { $str = ""; foreach ($pairs as $username => $password) { $str .= "$username:{SHA}$password

使用方法 复制代码 代码如下: $passwdHandler = new Htpasswd("/home/myuser/.htpasswd"); // Add a user with name "user1" and password "I prefer to use passphrase rather than password." if it doesn"t exist in .htpasswd. $passwdHandler -> addUser("user1", "I prefer to use passphrase rather than password."); // Delete the user "user1" if it exists in .htpasswd. $passwdHandler -> deleteUser("user1"); // Check if user "user1" exists in .htpasswd. if ($passwdHandler -> doesUserExist("user1")) { // User "user1" exists. }
