mysqli_fetch_row

Get a result row as an enumerated array (PHP 5)
mixed mysqli_fetch_row ( mysqli_result result )

Procedural style:

Object oriented style (method):

mysqli_result {
  mixed fetch_row();
}

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.

注意:

本函数对 PHP NULL 值设定 NULL 字段。

例 1281. 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 1282. 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);
