linux中解析.htpasswd文件的PHP类有需要的朋友可参考一下,介绍一个使用方法,实例代码如下:
- $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.
 - }
 
htpasswd类,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}$passwordn";
 - }
 - file_put_contents($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 (!emptyempty($clear_password)) {
 - return base64_encode(sha1($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 = '', $clear_password = '') {
 - if (!emptyempty($username) && !emptyempty($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, $all)) {
 - return true; //开源代码vcphp.com
 - } else {
 - return false;
 - }
 - }
 - public function getClearPassword($username) {
 - return strtolower(substr(sha1($username.$this -> salt), 4, 12));
 - }
 - }
