Sometimes, we will configure different domain access according to the difference between mobile and PC side. For this, we can judge the current access to the domain name, and then judge the end device, according to the judgment jump to the corresponding domain name access. As follows:

To determine the current access address, $_server[' Http_host '];if ($url = = ' Mobile URL ') {//Mobile Access address    if (!ismobile ()) {//terminal is PC, jump to PC-side URL    Echo ' <script>location.href= ' https://PC-end URL "</script>";    Exit;    }} else {                //PC access address    if (IsMobile ()) {        //terminal is mobile, jump to mobile URL        echo ' <script>location.href= ' https:// Mobile-access Address "</script>";        Exit;    }}
