.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}$password ";
}
file_put_contents($this -> file, $str);
}
private function read() {
$pairs = array();
$fh = fopen($this -> file, "r");
while (!feof($fh)) {
$pair_str = str_replace(" ", "", fgets($fh));
$pair_array = explode(":{SHA}", $pair_str);
if (count($pair_array) == 2) {
$pairs[$pair_array[0]] = $pair_array[1];
}
}
return $pairs;
}
private function getHash($clear_password = "") {
if (!empty($clear_password)) {
return base64_encode(sha1($clear_password, true));
} else {
return false;
}
}
public function __construct($file) {
if (file_exists($file)) {
$this -> file = $file;
} else {
die($file." doesn"t exist.");
return false;
}
}
public function addUser($username = "", $clear_password = "") {
if (!empty($username) && !empty($clear_password)) {
$all = $this -> read();
if (!array_key_exists($username, $all)) {
$all[$username] = $this -> getHash($clear_password);
$this -> write($all);
}
} else {
return false;
}
}
public function deleteUser($username = "") {
$all = $this -> read();
if (array_key_exists($username, $all)) {
unset($all[$username]);
$this -> write($all);
} else {
return false;
}
}
public function doesUserExist($username = "") {
$all = $this -> read();
if (array_key_exists($username, $all)) {
return true;
} else {
return false;
}
}
public function getClearPassword($username) {
return strtolower(substr(sha1($username.$this -> salt), 4, 12));
}
}

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.
}
