## Beispiele

Beispiel 1. Object oriented style
`<?php $mysqli = new mysqli("localhost", "my_user", "my_password", "world"); /* check connection */ if (mysqli_connect_errno()) { printf("Connect failed: %s\n", mysqli_connect_error()); exit(); } $query = "SELECT Name, SurfaceArea from Country ORDER BY Code LIMIT 5"; if ($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(); } /* close connection */ $mysqli->close(); ?>`

Beispiel 2. Procedural style
`<?php $link = mysqli_connect("localhost", "my_user", "my_password", "world"); /* check connection */ if (mysqli_connect_errno()) { printf("Connect failed: %s\n", mysqli_connect_error()); exit(); } $query = "SELECT Name, SurfaceArea from Country ORDER BY Code LIMIT 5"; if ($result = mysqli_query($link, $query)) { /* Get field information for all fields */ while ($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); printf("max. Len: %d\n", $finfo->max_length); printf("Flags: %d\n", $finfo->flags); printf("Type: %d\n\n", $finfo->type); } mysqli_free_result($result); } /* close connection */ mysqli_close($link); ?>`

Das oben gezeigte Beispiel erzeugt folgende Ausgabe:

    Column 1:
    Name:     Name
    Table:    Country
    max. Len: 11
    Flags:    1
    Type:     254

    Column 2:
    Name:     SurfaceArea
    Table:    Country
    max. Len: 10
    Flags:    32769
    Type:     4
