pg_result_error
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...
pg_result_seek
(PHP 4 >= 4.3.0, PHP 5)
pg_result_seek — 在结果资源中设定内部行偏移量
说明
array pg_result_seek
( resource
$result
, int $offset
)
pg_result_seek()
在结果资源中设定内部行偏移量。如果出错则返回 FALSE。
参见 pg_fetch_row()， pg_fetch_assoc()， pg_fetch_array()， pg_fetch_object() 和 pg_fetch_result()。
