PHP - 将值发送到外部aspx表单并获取值

Question

我想从ASP表单中获取价值，但我的所有尝试都失败了。 这是网站上的表格：https://www.dovera.sk/overenia/dlznici/zoznam-dlznikov

例如，我尝试使用此值36471224并在此网站上形成返回值。我正在尝试获取CURL请求，但我还没有成功。它是否可能（我绝望）？如果至少有人以正确的方式驾驶我，我将非常高兴。抱歉愚蠢的问题。

您可以使用Google开发者工具获取卷曲请求

假设变量没有变化和影响，你可以参考上面的解决方案

<强>解决方案：

<?php
function fetch_value($str, $find_start = '', $find_end = '')
{
    if ($find_start == '')
    {
        return '';
    }
    $start = strpos($str, $find_start);
    if ($start === false)
    {
        return '';
    }
    $length = strlen($find_start);
    $substr = substr($str, $start + $length);
    if ($find_end == '')
    {
        return $substr;
    }
    $end = strpos($substr, $find_end);
    if ($end === false)
    {
        return $substr;
    }
    return substr($substr, 0, $end);
}

$post_page = "https://ep.dovera.sk/PublicZone/Neplatici/NeplaticiWeb.aspx";
