# mysqli_fetch_row

(PHP 5)

mysqli_fetch_row

(no version information, might be only in CVS)

result->fetch_row() -- Get a result row as an enumerated array

## 说明

Procedural style:

mixed mysqli_fetch_row ( mysqli_result result )

Object oriented style (method):

class mysqli_result {
mixed fetch_row ( void )
}

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.

## 参数

`result`

  Procedural style only: A result set identifier returned by mysqli_query(), mysqli_store_result() or mysqli_use_result().

## 返回值

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

> 注意: 本函数对 PHP `NULL` 值设定 NULL 字段。

## 范例

例 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 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)
    Cape Coral (USA)
    Green Bay (USA)
    Santa Clara (USA)
