The below statement is only true if you're using ::fetch_row(), which must be called on a result object. Calling $stmt->store_result() effectively converts the statement object to a result object, which you can then call $stmt->fetch_row() on. (I don't know if it's actually converting the object from one type to another in the background, but that's the functional outworking of it.) If you use ::fetch() with a bound result, it is not necessary to call ::store_result. So your two options look like this: <?php //Method 1: bound result if ($stmt = $mysqli->prepare('SELECT name FROM employees')) { $stmt->execute(); $stmt->bind_result($name); while($stmt->fetch()) { echo $name; } } //Method 2: store_result if ($stmt = $mysqli->prepare('SELECT name FROM employees')) { $stmt->execute(); $stmt->store_result(); //"Converts" statement object to result object while($row = $stmt->fetch_row()) { echo $row[0]; } } ?> Another option is to use ::store_result() and ::fetch_array() instead of using a bound result.
