尝试在数据库中插入数据时出错，我收到以下消息：
注意：未定义的变量：第53行的C：\ wamp64 \ www \ email_verify \ index.php中的主机 注意：未定义的变量：第53行的C：\ wamp64 \ www \ email_verify \ index.php中的目标 注意：未定义的变量：第53行的C：\ wamp64 \ www \ email_verify \ index.php中的target_ip 致命错误：无法在第13行的C：\ wamp64 \ www \ email_verify \ index.php中重新声明domain_exists（）（之前在C：\ wamp64 \ www \ email_verify \ index.php：13中声明）
我该如何解决呢？

答案 0 :(得分：0)
不要在循环中声明函数。
把这个：
function domain_exists($abc)
{
$domain = substr(strrchr($abc, "@"), 1);
$arr = @dns_get_record($domain, DNS_MX);
if ($arr[0]['host'] == $domain && !empty($arr[0]['target'])) {
return $arr[0]['target'];
}
}
... 之前这一行：
foreach ($text as $abc) {
接下来，您需要将变量$target和$target_ip声明为与您尝试使用它们相同的级别，即与此行位于同一级别：
$insert = $connect->query("INSERT INTO `email_verify_list`(`primary_email`,`host_name`,`target`,`target_ip`,`session`,`created_by`, `created_date`, `created_ip`) VALUES ('$abc','$host','$target','$target_ip','$c_ip','$c_by','$c_date','$c_ip')")
