我在同一页面上有两个 php 表单现在问题是我通过 iframe 调用它们但是验证码不起作用，尽管我对具有不同输入字段的两个表单使用相同的脚本。现在发生的情况是，当我们第一次点击验证码并输入正确的验证码时，它会将我们带到您输入了错误的验证码，然后我们填写正确的验证码然后向我们显示谢谢...为什么当我们第一次输入时它不显示感谢正确的验证码？？？？？？

            curl_setopt($tuCurl, CURLOPT_RETURNTRANSFER, 1);    
            $tuData = curl_exec($tuCurl); 
            curl_close($tuCurl); 
            $userip = explode(',',$tuData);
            $ipcountry = str_replace('"', '', $userip[3]);

验证码图像代码通常存储在会话变量中。当您显示第二个表单时，您将覆盖第一个表单的验证码。
