Fetch the next row of a result set as an associative array

mysqli_result::fetch_assoc -- mysqli_fetch_assoc — Fetch the next row of a result set as an associative array

### Description

Object-oriented style

public mysqli_result::fetch_assoc(): array|null|false

Procedural style

mysqli_fetch_assoc(mysqli_result `$result`): array|null|false

Fetches one row of data from the result set and returns it as an associative array. Each subsequent call to this function will return the next row within the result set, or `null` if there are no more rows.

If two or more columns of the result have the same name, the last column will take precedence and overwrite any previous data. To access multiple columns with the same name, mysqli_fetch_row() may be used to fetch the numerically indexed array, or aliases may be used in the SQL query select list to give columns different names.

> Note: Field names returned by this function are case-sensitive.

> Note: This function sets NULL fields to the PHP `null` value.

### Parameters

`result`

  Procedural style only: A mysqli_result object returned by mysqli_query(), mysqli_store_result(), mysqli_use_result() or mysqli_stmt_get_result().

### Return Values

Returns an associative array representing the fetched row, where each key in the array represents the name of one of the result set's columns, `null` if there are no more rows in the result set, or `false` on failure.

### Examples

Example #1 mysqli_result::fetch_assoc() example

Object-oriented style

`<?php
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
$mysqli = new mysqli("localhost", "my_user", "my_password", "world");
$query = "SELECT Name, CountryCode FROM City ORDER BY ID DESC";
$result = $mysqli->query($query);
/* fetch associative array */
while ($row = $result->fetch_assoc()) {
printf("%s (%s)\n", $row["Name"], $row["CountryCode"]);
}`

Procedural style

`<?php
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
$mysqli = mysqli_connect("localhost", "my_user", "my_password", "world");
$query = "SELECT Name, CountryCode FROM City ORDER BY ID DESC";
$result = mysqli_query($mysqli, $query);
/* fetch associative array */
while ($row = mysqli_fetch_assoc($result)) {
printf("%s (%s)\n", $row["Name"], $row["CountryCode"]);
}`

The above examples will output something similar to:

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

Example #2 Comparison of mysqli_result iterator and mysqli_result::fetch_assoc() usage

mysqli_result can be iterated using `foreach`. The result set will always be iterated from the first row, regardless of the current position.

`<?php
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
$mysqli = new mysqli("localhost", "my_user", "my_password", "world");
$query = 'SELECT Name, CountryCode FROM City ORDER BY ID DESC';
// Using iterators
$result = $mysqli->query($query);
foreach ($result as $row) {
printf("%s (%s)\n", $row["Name"], $row["CountryCode"]);
}
echo "\n==================\n";
// Not using iterators
$result = $mysqli->query($query);
while ($row = $result->fetch_assoc()) {
printf("%s (%s)\n", $row["Name"], $row["CountryCode"]);
}`

The above example will output something similar to:

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