我有一个php变量,包含textarea的值,如下所示.

Name:Jay
Email:jayviru@demo.com
Contact:9876541230

现在我希望这些行在数组中如下所示.

Array
(
[Name] =>Jay
[Email] =>jayviru@demo.com
[Contact] =>9876541230
)

我在下面试过,但不会起作用: -

$test=explode("<br />", $text); 
print_r($test);

我有一个脚本，它向另一台服务器发送请求，但问题是IPv6不支持，所以如果我发送IPv6然后给出错误，所以我需要以下两个之一：

1. IPv4随时获取地址或
2. 获取两者IPv4和IPv6地址

我使用此代码获取IP地址

function getRealIP()
    {
        if (isset($_SERVER["HTTP_CLIENT_IP"])) {
            $ip = $_SERVER["HTTP_CLIENT_IP"];
        } elseif (isset($_SERVER["HTTP_X_FORWARDED_FOR"])) {
            $ip = $_SERVER["HTTP_X_FORWARDED_FOR"];
        } elseif (isset($_SERVER["HTTP_X_FORWARDED"])) {
            $ip = $_SERVER["HTTP_X_FORWARDED"];
        } elseif (isset($_SERVER["HTTP_FORWARDED_FOR"])) {
            $ip = $_SERVER["HTTP_FORWARDED_FOR"];
        } elseif (isset($_SERVER["HTTP_FORWARDED"])) {
            $ip = $_SERVER["HTTP_FORWARDED"];
        } else {
            $ip = $_SERVER["REMOTE_ADDR"];
        }

        // Strip any secondary IP etc from the IP address
        if (strpos($ip, ',') > 0) {
            $ip = substr($ip, 0, strpos($ip, …
