Question

I have this array and I want to print it somewhere else.
I have stored it in a user.class.php but I want to print it in feedback.php.

How do I do this? Because it keeps on telling me that it doesn’t know ‘$myarray’.

Please help 🙂 Thanks.

public function getFeedback($p_iUserid) {
    include("Connection.php"); //open db

    try
    {
        $sql = "SELECT FeedbackPatient FROM tblFeedback 
                WHERE fk_UserId = ".$p_iUserid."";

        $result = mysqli_query( $link, $sql );

        while( $row=mysqli_fetch_assoc($result) )
        {
            $myarray[] = $row['FeedbackPatient'];
            print_r($myarray);
        }
        mysqli_free_result( $result );
    }
    catch(Exception $e)
    {
        // no connection database
        $feedback = $e->getMessage();
    }
    mysqli_close($link);
}

I would just make it a return of the function:

public function getFeedback($p_iUserid) {
    include("Connection.php"); //open db

    $myarray = array();
    try
    {
        $sql = "SELECT FeedbackPatient FROM tblFeedback 
                WHERE fk_UserId = ".$p_iUserid."";

        $result = mysqli_query( $link, $sql );

        while( $row=mysqli_fetch_assoc($result) )
        {
            $myarray[] = $row['FeedbackPatient'];
        }
        mysqli_free_result( $result );
    }
    catch(Exception $e)
    {
        // no connection database
        $feedback = $e->getMessage();
    }
    mysqli_close($link);
    return $myarray;
}

Then in feedback.php:

$myarray = $user->getFeedback($user_id);
if($myarray) {
  // do something with $myarray
  print_r($myarray);
}
