用来解析.htpasswd文件的PHP类

  .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\n";

  }

  file_put_contents($this -> file, $str);

  }

  private function read() {

  $pairs = array();

  $fh = fopen($this -> file, 'r');

  while (!feof($fh)) {

  $pair_str = str_replace("\n", '', fgets($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.

  }
