    说明

    面向对象风格

    publicmysqli_result::fetch_row(): array|null|false

    过程化风格

    mysqli_fetch_row(mysqli_result$result): array|null|false

    Fetches one row of data from the result set and returns it as an enumerated array, where each column is stored in an array offset starting from 0 (zero). Each subsequent call to this function will return the next row within the result set, or null if there are no more rows.

    注意: 此函数将 NULL 字段设置为 PHP null 值。

    参数

    result

    仅以过程化样式：由 mysqli_query()、mysqli_store_result()、 mysqli_use_result()、mysqli_stmt_get_result() 返回的 mysqli_result 对象。

    返回值

    Returns an enumerated array representing the fetched row, null if there are no more rows in the result set, 或者在失败时返回 false.

    面向对象风格

    <?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);


    while ($row = $result->fetch_row()) {
    printf("%s (%s)\n", $row[0], $row[1]);
    }

    过程化风格

    <?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);


    while ($row = mysqli_fetch_row($result)) {
    printf("%s (%s)\n", $row[0], $row[1]);
    }

    以上示例的输出类似于：

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