result

순차 형식 전용: mysqli_query()mysqli_store_result()mysqli_use_result()가 반환한 결과셋 식별자.

반환값

Returns an associative array of strings representing the fetched row in the result set, where each key in the array represents the name of one of the result set's columns or NULL if there are no more rows in resultset.

If two or more columns of the result have the same field names, the last column will take precedence. To access the other column(s) of the same name, you either need to access the result with numeric indices by using mysqli_fetch_row() or add alias names.

    exit();
}

$query "SELECT Name, CountryCode FROM City ORDER by ID DESC LIMIT 50,5";

if (
$result $mysqli->query($query)) {

    
/* fetch associative array */
    
while ($row $result->fetch_assoc()) {
        
printf ("%s (%s)\n"$row["Name"], $row["CountryCode"]);
