Question

我有一个带有联系表单的网站，当我提交详细信息时，我收到有关已弃用eregi()的错误消息。这是似乎有问题的代码块。我不知道php，所以有人可以伸手吗？

if (email_is_valid($youremail) && !eregi("\r",$youremail) && !eregi("\n",$youremail) && $yourname != "" && $yourmessage != "" && substr(md5($user_answer),5,10) === $answer) {
              mail($to,$subject,$message,$headers);
              $yourname = '';
              $youremail = '';
              $yourmessage = '';
              echo '<p style="color: #200041; text-align: center;">'.$contact_submitted.'</p>';
            }

Answer 1

不推荐使用Eregi，因此请将其从代码中删除：

if (email_is_valid($youremail)&& $yourname != "" && $yourmessage != "" && substr(md5($user_answer),5,10) === $answer) {  
     mail($to,$subject,$message,$headers);
     $yourname = ''; 
     $youremail = ''; 
     $yourmessage = ''; 
     echo ''.$contact_submitted.'

你可以忘掉它，因为它只检查新的线路标志如果你想保持新的行检查，用preg_match函数替换eregi（但请阅读有关它的手册）。

eregi()已弃用。所以你可以使用preg_match()

您的代码将是

<?php
    if (email_is_valid($youremail) && $yourname != "" && $yourmessage != "" && substr(md5($user_answer),5,10) == '$answer')
    {
        mail($to,$subject,$message,$headers);
        $yourname = '';
        $youremail = '';
        $yourmessage = '';
        echo '<p style="color: #200041; text-align: center;">'.$contact_submitted.'</p>';
    }
    else
    {
        echo '<p style="color: red; text-align: center;">Error</p>';
    }

PHP联系表单验证？
