用来解析.htpasswd文件的PHP类，
前端之家小编觉得挺不错的，现在分享给大家，也给大家做个参考。
.htpasswd 文件示例：
user1:{SHA}kGPaD671VNU0OU5lqLiN/h6Q6ac=
user2:{SHA}npMqPEX3kPQTo+x/+ZckHDrIcQI=
user3:{SHA}q1Fh2LTUjjkncp11m0M9WUH5Zrw=
<div class="codetitle"><a style="CURSOR: pointer" data="51520" class="copybut" id="copybut51520" onclick="doCopy('code51520')"> 代码如下:
<div class="codebody" id="code51520">
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);
}

}
}
public function deleteUser($username = '') {
$all = $this -> read();
