mysqli_fetch_assoc

mysqli->fetch_assoc()

(PHP 5)

mysqli->fetch_assoc() — Fetch a result row as an associative array

Beschreibung

Procedural style:

array mysqli_fetch_assoc ( mysqli_result $result )

Object oriented style (method):

mysqli_result
array fetch_assoc ( void )

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

Procedural style only: A result set identifier returned by mysqli_query(), mysqli_store_result() or mysqli_use_result().

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

Example#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();
?>

Example#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);
?>
