$finfo = $result->fetch_field_direct(1);

    
printf("Name:     %s\n", $finfo->name);
    
printf("Table:    %s\n", $finfo->table);
    
printf("max. Len: %d\n", $finfo->max_length);

Example 2. Procedural style

<?php
$link

/* check connection */
if (mysqli_connect_errno()) {
    
printf("Connect failed: %s\n", mysqli_connect_error());
    exit();
}

$query = "SELECT Name, SurfaceArea from Country ORDER BY Name LIMIT 5";

if (
$result = mysqli_query($link, $query)) {

    
/* Get field information for column 'SurfaceArea' */
    
$finfo = mysqli_fetch_field_direct($result, 1);

    
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);
