推荐答案

OFC这只是一个样本，将读取当前的文件，找到指定的用户名和更改要么是用户名密码。

Ofc this is just a sample, that will read your current file, find the given username and change either it is password of username.

请记住，这code是不是安全的，您仍然需要解析的用户名和密码，所以它不会破坏你的文件。

    $username = $_POST['user'];
    $password = $_POST['pass'];
    $new_username = $_POST['newuser'];
    $new_password = $_POST['newpass'];
    $action = $_POST['action'];
    //read the file into an array
    $lines = explode("n", file_get_contents('.htpasswd'));

    //read the array and change the data if found
    $new_file = "";
    foreach($lines as $line)
    {
        $line = preg_replace('/s+/','',$line); // remove spaces
        if ($line) {
            list($user, $pass) = split(":", $line, 2);
            if ($user == $username) {
                if ($action == "password") {
                    $new_file .= $user.':'.$new_password."n";
                } else {
                    $new_file .= $new_username.':'.$pass."n";
                }
            } else {
                $new_file .= $user.':'.$pass."n";
            }
        }
    }

    //save the information
    $f=fopen(".htpasswd","w") or die("couldn't open the file");
    fwrite($f,$new_file);
    fclose($f);
