mysqli_result::fetch_assoc -- mysqli_fetch_assoc — Fetch a result row as an associative array

### Beschreibung

Objektorientierter Stil

array mysqli_result::fetch_assoc ( void )

Prozeduraler Stil

array mysqli_fetch_assoc ( mysqli_result `$result` )

Returns an associative array that corresponds to the fetched row or `NULL` if there are no more rows.

> Hinweis: Feldnamen, die von dieser Funktion zurückgegeben werden, unterscheiden sich in der Groß-/Kleinschreibung.

> Hinweis: Diese Funktion setzt NULL-Felder auf den PHP Wert-`NULL`.

### Parameter-Liste

`result`

  Nur bei prozeduralem Aufruf: Ein von mysqli_query(), mysqli_store_result() oder mysqli_use_result() zurückgegebenes Ergebnisobjekt.

### Rückgabewerte

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.

### Beispiele

Beispiel #1 Objektorientierter Stil

`<?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();
}
$query = "SELECT Name, CountryCode FROM City ORDER by ID DESC LIMIT 50,5";
if ($result = $mysqli->query($query)) {
/* fetch associative array */
while ($row = $result->fetch_assoc()) {
printf ("%s (%s)\n", $row["Name"], $row["CountryCode"]);
}
/* free result set */
$result->free();
}
/* close connection */
$mysqli->close();
?>`

Beispiel #2 Prozeduraler Stil

`<?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();
}
$query = "SELECT Name, CountryCode FROM City ORDER by ID DESC LIMIT 50,5";
if ($result = mysqli_query($link, $query)) {
/* fetch associative array */
while ($row = mysqli_fetch_assoc($result)) {
printf ("%s (%s)\n", $row["Name"], $row["CountryCode"]);
}
/* free result set */
mysqli_free_result($result);
}
/* close connection */
mysqli_close($link);
?>`

Die obigen Bespiele erzeugen folgende Ausgabe:

    Pueblo (USA)
    Arvada (USA)
    Cape Coral (USA)
    Green Bay (USA)
    Santa Clara (USA)

Beispiel #3 A mysqli_result example comparing iterator usage

`<?php
$c = mysqli_connect('127.0.0.1','user', 'pass');
// Using iterators (support was added with PHP 5.4)
foreach ( $c->query('SELECT user,host FROM mysql.user') as $row ) {
printf("'%s'@'%s'\n", $row['user'], $row['host']);
}
echo "\n==================\n";
// Not using iterators
$result = $c->query('SELECT user,host FROM mysql.user');
while ($row = $result->fetch_assoc()) {
printf("'%s'@'%s'\n", $row['user'], $row['host']);
}
?>`

Das oben gezeigte Beispiel erzeugt eine ähnliche Ausgabe wie:

    'root'@'192.168.1.1'
    'root'@'127.0.0.1'
    'dude'@'localhost'
    'lebowski'@'localhost'

    ==================

    'root'@'192.168.1.1'
    'root'@'127.0.0.1'
    'dude'@'localhost'
    'lebowski'@'localhost'
