- 1.Include and instantiate the class:
- 2.
- 3.include("Mobile_Detect.php");
- 4.$detect = new Mobile_Detect();
- 5.Check for a specific platform:
- 6.
- 7.if ($detect->isAndroid()) {
- 8. // code to run for the Google Android platform
- 9.}
- 10.Available methods are isAndroid(), isAndroidtablet(), isIphone(), isIpad(), isBlackberry(), isBlackberrytablet(), isPalm(), isWindowsphone(), isWindows(), isGeneric(). Alternatively, if you are only interested in checking to see if the user is using a mobile device, without caring for specific platform:
- 11.
- 12.if ($detect->isMobile()) {
- 13. // any mobile platform
- 14.}
