Can someone help me out?

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

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

PHP: Only variables should be passed by reference – James' Desk, This is due to one of the reason that you need to pass a real variable and not a function that returns an array. It is because only actual variable  Often times developers end up with this error: Notice: Only variables should be passed by reference in <file_name>.php on line <line_number> This is due to one of the reason that you need to pass a real variable and not a function that returns an array.

Avoid function call in Statement#bindParam, its return value cannot be passed as reference.

Try to separate the function call: $pwd = password_hash($_POST['password'], PASSWORD_BCRYPT); $stmt->bindParam(':password', $pwd);

Passing by Reference - Manual, Notice: Only variables should be passed by reference ?> add a note Some have noticed that reference parameters can not be assigned a default value. PHP complains because end() expects a reference to something that it wants to change (which can be a variable only). You however pass the result of explode() directly to end() without saving it to a variable first.

The second parameter of bindParam is a variable reference. Since a function return cannot be referenced, it fails to strictly meet the needs of the bindParam parameter.

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