maxdb_fetch_row -- maxdb_result::fetch_row — Get a result row as an enumerated array

### 说明

过程化风格

maxdb_fetch_row ( resource `$result` ) : mixed

面向对象风格

maxdb_result::fetch_row ( void ) : mixed

Returns an array that corresponds to the fetched row, or `NULL` if there are no more rows.

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

### 返回值

maxdb_fetch_row() returns an array that corresponds to the fetched row or `NULL` if there are no more rows in result set.

> Note: 此函数将 NULL 字段设置为 PHP `NULL` 值。

Example #1 面向对象风格

    <?php
    $maxdb = new maxdb("localhost", "MONA", "RED", "DEMODB");

    /* check connection */
    if (maxdb_connect_errno()) {
       printf("Connect failed: %s\n", maxdb_connect_error());
       exit();
    }

    $query = "SELECT name, state FROM hotel.city ORDER by zip";

    if ($result = $maxdb->query($query)) {

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

       /* free result set */
       $result->close();
    }

    /* close connection */
    $maxdb->close();
    ?>

Example #2 过程化风格

    <?php
    $link = maxdb_connect("localhost", "MONA", "RED", "DEMODB");

    /* check connection */
    if (maxdb_connect_errno()) {
       printf("Connect failed: %s\n", maxdb_connect_error());
       exit();
    }

    $query = "SELECT name, state FROM hotel.city ORDER by zip";

    if ($result = maxdb_query($link, $query)) {

       /* fetch enumerated array */
       while ($row = maxdb_fetch_row($result)) {
           printf ("%s (%s)\n", $row[0], $row[1]);
       }

       /* free result set */
       maxdb_free_result($result);
    }

    /* close connection */
    maxdb_close($link);
    ?>
