Question:PHP: Detect Mobile User Agent Using preg_match Regular Expression


Want a more reliable way to detect mobile visitors than the CSS media query? Using PHP, you can change the whole site or redirect users to a different site when they browse from a mobile device, or just change the CSS. This method relies on the HTTP_USER_AGENT value in the $_SERVER super global. Since this value ultimately comes from the client's browser, it can be spoofed, though don't expect a large portion of visitors to know how. I wrote a post on how to spoof your user agent on Android for those curious. $mobile_agents = '!(tablet|pad|mobile|phone|symbian|android|ipod|ios|blackberry|webos)!i'; if(preg_match($mobile_agents, $_SERVER['HTTP_USER_AGENT'])) { // Mobile! }
