使用 crypt() 和 password_hash() 函数加密后密码不匹配

I modified my old post. I tried the crypt() function and now trying to work with password_hash() and password_verify() to verify the encrypted password coming from database but on each call, password_hash() function retuns a different encrypted string and password_verify() cannot match it.

我就是这样做的.

 //please ignore the syntax error if any

$data = '11';
$dbpass = password_hash($data, PASSWORD_BCRYPT);
echo $dbpass;  // displays the random strings on each page refresh.

一旦密码被保存到数据库中，在登录过程中不会匹配.下面是我的实际功能.

   private function process_data($password){
    $password = __STR.$password.__STR;
    return  password_hash($password, PASSWORD_BCRYPT);

  }
  private function processed($login_password, $dbpassword){
    $login_password = __STR.$login_password.__STR;
    return password_verify($login_password, $dbpassword);
  }

function saveUser($username, $password) {
    $hash = password_hash($password, PASSWORD_BCRYPT);
    // save $username and $hash to db
}
function login($username, $password) {
    // fetch $hash from db
    return password_verify($password, $hash);
}

$hash = '$2y$04$usesomesillystringfore7hnbRJHxXVLeakoG8K30oukPsA.ztMG';
$test = crypt("password", $hash);
$pass = $test == $hash;

echo "Test for functionality of compat library: " . ($pass ? "Pass" : "Fail");
echo "
";
