### Descripción

Object oriented style (method):

array mysqli_result::fetch_assoc ( void )

Procedural style:

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.

> Note: Los nombres de campos retornados por esta función diferencian entre mayusculas y minusculas.

> Note: Esta funcion define campos NULL como valores PHP `NULL`.

### Lista de parámetros

`result`

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

### Valores retornados

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.

### Ejemplos

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

$link = mysqli_connect("localhost", "my_user", "my_password", "world");

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"]);

mysqli_free_result($result);
