How do I count query result rows?

Question

What should I replace \'CODE TO VERIFY IF QUERY RESULT ROW IS = 1\' for?
I\'ve tried many ways using num_rows but it won\'t work.

My PHP code:

Answer 1

you could just do

    if($row = mysqli_fetch_assoc($query)) {

    }

also you may want to save your username and password in one file as constants

Answer 2

$query->num_rows;

or

mysqli_num_rows($query);

Answer 3

You can use:

$stmt=$mysqli->prepare("select `id` from `agahicustomer` where `city`=?");
    $stmt->bind_param("s",$cityid);
    $stmt->execute();
    $stmt->store_result();
    $stmt->bind_result($id);
    return $stmt->affected_rows;
    $stmt->close();

Answer 4

Also you can use this sql query :

Select count(*) from table
