• mysqli_result::fetch_array

  mysqli_fetch_array

  Fetch the next row of a result set as an associative, a numeric array, or both

Description

Object-oriented style

public array|null|false mysqli_result::fetch_array(int mode= =MYSQLI_BOTH);

Procedural style

array|null|false mysqli_fetch_array(mysqli_result result,
                                    int mode= =MYSQLI_BOTH);

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

In addition to storing the data in the numeric indices of the result array, this function can also store the data in associative indices by using the field names of the result set as keys.

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, the numerically indexed version of the row must be used.

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.

mode

This optional parameter is a constant indicating what type of array should be produced from the current row data. The possible values for this parameter are the constants MYSQLI_ASSOC, MYSQLI_NUM, or MYSQLI_BOTH.

By using the MYSQLI_ASSOC constant this function will behave identically to the mysqli_fetch_assoc, while MYSQLI_NUM will behave identically to the mysqli_fetch_row function. The final option MYSQLI_BOTH will create a single array with the attributes of both.

Return Values

Returns an array representing the fetched row, null if there are no more rows in the result set, or false on failure.

Examples

Example 3.109 mysqli_result::fetch_array 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 LIMIT 3";
$result = $mysqli->query($query);

/* numeric array */
$row = $result->fetch_array(MYSQLI_NUM);
printf("%s (%s)\n", $row[0], $row[1]);

/* associative array */
$row = $result->fetch_array(MYSQLI_ASSOC);
printf("%s (%s)\n", $row["Name"], $row["CountryCode"]);

/* associative and numeric array */
$row = $result->fetch_array(MYSQLI_BOTH);
printf("%s (%s)\n", $row[0], $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 LIMIT 3";
$result = mysqli_query($mysqli, $query);

/* numeric array */
$row = mysqli_fetch_array($result, MYSQLI_NUM);
printf("%s (%s)\n", $row[0], $row[1]);

/* associative array */
$row = mysqli_fetch_array($result, MYSQLI_ASSOC);
printf("%s (%s)\n", $row["Name"], $row["CountryCode"]);

/* associative and numeric array */
$row = mysqli_fetch_array($result, MYSQLI_BOTH);
printf("%s (%s)\n", $row[0], $row["CountryCode"]);

The above examples will output something similar to:

Kabul (AFG)
Qandahar (AFG)
Herat (AFG)
