# db2_fetch_into

(no version information, might be only in CVS)

db2_fetch_into -- Returns an array, indexed by column position, representing a row in a result set

## 说明

array db2_fetch_into ( resource stmt [, int row_number] )

警告
本函数是实验性的。本函数的行为，包括函数名称以及其它任何关于本函数的文档可能会在没有通知的情况下随 PHP 以后的发布而改变。使用本函数风险自担。

Returns an array, indexed by column position, representing a row in a result set. The columns are 0-indexed.

## 参数

stmt

  A valid stmt resource containing a result set.

row_number

  Requests a specific 1-indexed row from the result set. Passing this parameter results in a PHP warning if the result set uses a forward-only cursor.

## 返回值

Returns a 0-indexed array with column values indexed by the column position representing the next or requested row in the result set. Returns `FALSE` if there are no rows left in the result set, or if the row requested by row_number does not exist in the result set.

## 例

例子 1. Iterating through a forward-only cursor If you call db2_fetch_into() without a specific row number, it automatically retrieves the next row in the result set.
`<?php $sql = "SELECT id, name, breed, weight FROM animals ORDER BY breed"; $stmt = db2_prepare($conn, $sql); $result = db2_execute($stmt, $sql); while ($row = db2_fetch_into($result)) { printf ("%-5d %-16s %-32s %10s\n", $row[0], $row[1], $row[2], $row[3]); } ?>`
上例将输出：
    0     Pook             cat                                    3.20
    5     Rickety Ride     goat                                   9.70
    2     Smarty           horse                                350.00

例子 2. Retrieving specific rows with db2_fetch_assoc() from a scrollable cursor If your result set uses a scrollable cursor, you can call db2_fetch_assoc() with a specific row number. The following example retrieves every other row in the result set, starting with the second row.
`<?php $sql = "SELECT id, name, breed, weight FROM animals ORDER BY breed"; $result = db2_exec($stmt, $sql, array('cursor' => DB2_SCROLLABLE)); $i=2; while ($row = db2_fetch_into($result, $i)) { printf ("%-5d %-16s %-32s %10s\n", $row[0], $row[1], $row[2], $row[3]); $i = $i + 2; } ?>`
上例将输出：
    0     Pook             cat                                    3.20
    5     Rickety Ride     goat                                   9.70
    2     Smarty           horse                                350.00
