Description

Procedural style:

array mysqli_fetch_assoc ( mysqli_result result )

Object oriented style (method):

class mysqli_result {

array fetch_assoc ( void )

}

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

The mysqli_fetch_assoc() function is used to return an associative array representing the next row in the result set for the result represented by the result parameter, where each key in the array represents the name of one of the result set's columns.

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.

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

Anmerkung: Diese Funktion setzt NULL Felder auf den PHP Wert NULL.

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, 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->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, 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);
?>
