  • pg_result_seek()

    (PHP 4 >= 4.3.0, PHP 5, PHP 7)

    在结果资源中设定内部行偏移量

    说明

    pg_result_seek(resource $result,int $offset): array

    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()。

    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...
