result->fetch_row

(PECL maxdb >= 1.0)

maxdb_fetch_row -- result->fetch_rowGet a result row as an enumerated array

说明

Procedural style:

mixed maxdb_fetch_row ( resource $result )

Object oriented style (method):

result
mixed fetch_row ( void )

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: 本函数对 PHP NULL 值设定 NULL 字段。

范例

Example #1 Object oriented style

<?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 Procedural style

<?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);
?>
