$query = "SELECT Name, SurfaceArea from Country ORDER BY Code LIMIT 5";
if ($result = $mysqli->query($query)) {
/* Get field information for all columns */
while ($finfo = $result->fetch_field()) {
/* get fieldpointer offset */
$currentfield = $result->current_field;
printf("Column %d:\n", $currentfield);
printf("Name: %s\n", $finfo->name);
printf("Table: %s\n", $finfo->table);
printf("max. Len: %d\n", $finfo->max_length);
printf("Flags: %d\n", $finfo->flags);
printf("Type: %d\n\n", $finfo->type);
}
$result->close();
}

while ($finfo = mysqli_fetch_field($result)) {
/* get fieldpointer offset */
$currentfield = mysqli_field_tell($result);
printf("Column %d:\n", $currentfield);
printf("Name: %s\n", $finfo->name);
printf("Table: %s\n", $finfo->table);
