Php Mysqli Undefined Function - php

Question

When executing the
mysqli_bind_result();
I receive an error saying "Call to undefined function".
My code looks as follows:
$mysqli = new mysqli("localhost", "root", "", "*****");
if(isset($_POST['login'])){
if($_POST['username']){
if($_POST['password']){
$username = $_POST['username'];
$passwordtmp = $_POST['password'];
$password = md5(md5($passwordtmp));
//Connect to Database//
if ($mysqli->connect_errno) {
echo "Failed to connect to MySQL: (" . $mysqli->connect_errno . ") " . $mysqli->connect_error;
}
//Check if user exist in database//
$query = mysqli_query($mysqli,"SELECT * FROM users WHERE username = '$username'");
$numrows = mysqli_num_rows($query);
if($numrows == 1){
if($stmt = mysqli_prepare($mysqli, "SELECT password FROM users WHERE username = '$username'")){
mysqli_execute($stmt);
mysqli_bind_result($stmt,$passw);
while(mysqli_stmt_fetch($stmt)){
$pass = $passw;
}
Additional Information:
I transfered this code from a different computer to my laptop using the same connection to my mysql database.
$mysqli = new mysqli("localhost", "root", "", "*****");
I copied the exact database to my laptop and both my computer and laptop are using wamp.
I am wondering if this could be a connection to the database issue, or just a coding error. But it works perfectly on my original computer without any problems.
Thank you in advance. I will give credit for helpful answers.

You're probably using PHP > 5.4, as the function mysqli_bind_result was removed in PHP 5.4.
Change it to mysqli_stmt_bind_result and that should fix your problem.
mysqli_stmt_bind_result($stmt, $passw);
