pg_result_seek — 在 result 实例中设定内部行偏移量

示例 #1 pg_result_seek() 示例
<?php
// 连接到数据库
$conn = pg_pconnect("dbname=publisher");
// 执行查询
$result = pg_query($conn, "SELECT author, email FROM authors");
// 寻找第三行（假设有 3 行）
pg_result_seek($result, 2);
// 获取第三行记录
$row = pg_fetch_row($result);
?>
Ah, this is a handy feature for resetting the record index, for example, if you're used pg_fetch_{row,array,assoc} to iterate over the result set, and you want to do it again later on, without reexecuting your query. Something like:
<?php pg_result_seek($result, 0); ?>
will allow you to iterate over the result set all over again...
