说明array db2_fetch_array ( 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_array() 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_array($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

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_array($result, $i)) {
printf ("%-5d %-16s %-32s %10s\n",
$row[0], $row[1], $row[2], $row[3]);
$i = $i + 2;
}
?>
