Açıklama

Nesne yönelimli kullanım

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

Yordamsal kullanım

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

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.

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.

Dönen Değerler

Returns an array representing the fetched row, null if there are no more rows in the result set, başarısızlık durumunda false döner.

$result = mysqli_query($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:
