PHP method: Use the "_ SERVER" array "HTTP_USER_AGENT" item of PHP to obtain the information of the user agent on the page to complete this task. the code is as follows:

Winows/chrome output result:

Mozilla/5.0 (Windows NT 6.2; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/30.0.1599.69 Safari/537.36

The output result in ios7/weixin is as follows:

Mozilla/5.0 (iPhone; CPU iPhone OS 7_0_4 like Mac OS X) AppleWebKit/537.51.1 (KHTML, like Gecko) Mobile/11B554a MicroMessenger/5.0.3

The string shows that "MicroMessenger" is the browser version, so you can use the "MicroMessenger" parameter to determine whether the access source is "browser". the code is as follows:

if(strpos($_SERVER['HTTP_USER_AGENT'],"MicroMessenger ")) {     echo "Hello Weixin";//phprm.com}

The Javascript method code is as follows:

function isweixin(){     var ua = navigator.userAgent.toLowerCase();     if(ua.match(/MicroMessenger/i)=="micromessenger") {         return true;     } else {         return false;     } }
