只有变量应该通过引用传递..需要一些帮助:)（PHP）

Question

Here is what it's saying:

Notice: Only variables should be passed by reference in C:\xampp\htdocs\loginegister.php on line 20

In line 20, I have

$stmt->bindParam(':password', password_hash($_POST['password'], PASSWORD_BCRYPT));

Can someone help me out?

Answer 1

Store value of hash in a variable and then pass it.

$password = password_hash($_POST['password'], PASSWORD_BCRYPT);
$stmt->bindParam(':password', $password);
