db2_fetch_row -- Sets the result set pointer to the next row or requested row

## 说明

bool db2_fetch_row ( 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。

Use db2_fetch_row() to iterate through a result set, or to point to a specific row in a result set if you requested a scrollable cursor.

To retrieve individual fields from the result set, call the db2_result() function.

Rather than calling db2_fetch_row() and db2_result(), most applications will call one of db2_fetch_assoc(), db2_fetch_both(), or db2_fetch_into() to advance the result set pointer and return a complete row as an array.

## 参数

stmt

  A valid stmt resource.

row_number

  With scrollable cursors, you can request a specific row number in the result set. Row numbering is 1-indexed.

## 返回值

Returns `TRUE` if the requested row exists in the result set. Returns `FALSE` if the requested row does not exist in the result set.

## 例

例子 1. Iterating through a result set The following example demonstrates how to iterate through a result set with db2_fetch_row() and retrieve columns from the result set with db2_result().
`<?php $sql = 'SELECT name, breed FROM animals WHERE weight < ?'; $stmt = db2_prepare($conn, $sql); db2_execute($stmt, array(10)); while (db2_fetch_row($stmt)) { $name = db2_result($stmt, 0); $breed = db2_result($stmt, 1); print "$name $breed"; } ?>`
上例将输出：
    cat Pook
    gold fish Bubbles
    budgerigar Gizmo
    goat Rickety Ride
