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);
?>
