Description

Procedural style:

mixed mysqli_fetch_row ( mysqli_result result )

Object oriented style (method):

class mysqli_result {

mixed fetch_row ( void )

}

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

mysqli_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 mysqli_fetch_row() function will return the next row within the result set, or FALSE if there are no more rows.

返回值

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

注: 本函数对 PHP NULL 值设定 NULL 字段。

例

例子 1. Object oriented style


<?php
$mysqli = new mysqli("localhost", "my_user", "my_password", "world");

/* check connection */
if (mysqli_connect_errno()) {
    printf("Connect failed: %s\n", mysqli_connect_error());
    exit();
}
 
$query = "SELECT Name, CountryCode FROM City ORDER by ID DESC LIMIT 50,5";

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

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

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

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

例子 2. Procedural style


<?php
$link = mysqli_connect("localhost", "my_user", "my_password", "world");

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

$query = "SELECT Name, CountryCode FROM City ORDER by ID DESC LIMIT 50,5";

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

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

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

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

上例将输出：

Pueblo (USA)
Arvada (USA)
