php获取域名,判断是否是https或者http

php获取域名,判断是否是https或者http.php 判断http还是https,以及获得当前url的方法详解,具有很好的参考价值.

第一种方法:

//判断是否HTTPS
function isHTTPS(){
    if (defined('HTTPS') && HTTPS) return true;
    if (!isset($_SERVER)) return FALSE;
    if (!isset($_SERVER['HTTPS'])) return FALSE;
    if ($_SERVER['HTTPS'] === 1) {  //Apache
        return TRUE;
    } elseif ($_SERVER['HTTPS'] === 'on') { //IIS
        return TRUE;
    } elseif ($_SERVER['SERVER_PORT'] == 443) { //其他
        return TRUE;
    }
    return FALSE;
}
$host_config = (isHTTPS() ? 'https://' : 'http://') . $_SERVER['HTTP_HOST']; //获取域名
echo  $host_config;

第二种方法:

$http_type = ((isset($_SERVER['HTTPS']) && $_SERVER['HTTPS'] == 'on') || (isset($_SERVER['HTTP_X_FORWARDED_PROTO']) && $_SERVER['HTTP_X_FORWARDED_PROTO'] == 'https')) ? 'https://' : 'http://';
echo $http_type . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];
