如何使用password_hash存储bcrypt salt

我使用password_compat.php来使用password_hash和password_verify函数。我用的是河豚算法。password_verify似乎不起作用，它与数据库中存储的哈希不匹配。我必须用password_verify指定算法还是salt？

reigster脚本：

            $hash = password_hash($pass, PASSWORD_BCRYPT);
            $qry = "INSERT INTO users (email, fname, lname, gender, p4s5) VALUES ('$email', '$fname', '$lname', '$gender', '$hash')";
            $result = mysqli_query($dblink, $qry) or die(mysqli_error($dblink));

登录脚本：

        $qry = "SELECT * FROM users WHERE email='$email' LIMIT 1";
        $result = mysqli_query($dblink, $qry);
        if (!mysqli_num_rows($result) > 0) {
            // email not in database, error
            $loginErrors .= "<li>Username or password wrong</li>";
        } else {
            $row = mysqli_fetch_assoc($result);
            // verify password;
            $hash = $row["p4s5"];
            if (password_verify($pass, $hash)) {
                // not same, error
                $loginErrors .= "<li>Username or password wrong</li>";
            } else {
                // login user
                $id = $row["id"];
                $fname = $row["fname"];
                $lname = $row["lname"];
                login($id, $email, $fname, $lname);
                header("Location: ".$_SESSION["last-page"]);
            }
        }

表格结构：

创建表users(id int（11）NOT NULL AUT…
