我有一个网站要剪贴http://cbseaff.nic.in/cbse_aff/schdir_Report/userview.aspx，我想在其中列出获取Region的{{1}}中学校的列表。
为此，我编写了以下Delhi代码。
PHP
现在，如果您注意到在<?php
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,"http://cbseaff.nic.in/cbse_aff/schdir_Report/userview.aspx");
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS,

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$server_output = curl_exec($ch);
echo $server_output;
curl_close ($ch);的末尾，我已经通过了POSTFIELDS，这是前25个结果。
现在，为了从26-50继续前进，我将POST_FIELD更改为Search=Search。
这是我完整的POSTFIELD数据Button1=Next+%3E%3E

现在的问题是我该如何前进。由于这里没有Button1=Next。
我也尝试将其放入循环中，但仍然会继续返回前25个结果。
因此，对此提出任何想法。
