Using password_verify in PHP

I am developing a login system for an iOS app.

This is part of the PHP script that I am using to send a JSON response to the app:

if(isset($_POST['correo']) && isset($_POST['pass']) && $_POST['key'] == "123456")
{


    $password = $_POST['pass'];



    $q = mysqli_query($mysqli,"SELECT * FROM users WHERE email = '".$_POST['correo']."' AND 
    encrypted_password = '".$_POST['pass']."'") or die (mysqli_error());

    if(mysqli_num_rows($q) >= 1){
        $r = mysqli_fetch_array($q);

// this is the hash of the password in above example
            $hash = $r['encrypted_password'];

            if (password_verify($password, $hash)) {

                $results = Array("error" => "1","mensaje" => "su ID es ".$r['id'],"nombre" => $r['nombre'],"apellidos" => $r['apellidos'],"email" => $r['email'],
        "imagen" => $r['imagen'],"unidad" => $r['unidad']);

            } else {
                $results = Array("error" => "2","mensaje" => " acceso denegado ");
            }

    }else{
        $results = Array("error" => "3","mensaje" => "no existe");
    }

}

echo json_encode($results);

My issue is about using password_verify in PHP. I want to know if it should work as it is in the script or not, then the JSON response is not received in the app.

Thank you

You don't need to match password in WHERE condition, something like:

$q = mysqli_query($mysqli,"SELECT * FROM users WHERE email = '".$_POST['correo']."'") or die (mysqli_error());

        if(mysqli_num_rows($q) >= 1){
                $r = mysqli_fetch_array($q);



                // this is the hash of the password in above example
                $hash = $r['encrypted_password'];

                //you need to match the password from form post against password from DB using password_hash    

                if (password_verify($password, $hash)) {
