Detecting BlackBerry and Iphone Browsers in JavaScript or PHP

Question

Answer 1

You need to check the User-Agent header:

if (preg_match("/(BlackBerry|(iP(hone|od))/i", $_SERVER['HTTP_USER_AGENT'])) ) {
    ...
}

Answer 2

The $_SERVER['HTTP_USER_AGENT'] contains word "BlackBerry" or "iPhone" respectively. "iPod" too if it's iPod Touch.

Answer 3

Very easy will be to parse USER-AGENT string or get_browser() PHP function. Try :

echo $_SERVER['HTTP_USER_AGENT'];
var_dump(get_browser(null, true));

Every browser is sending own HTTP_USER_AGENT string.

Mobile devices USER_AGENT list

For completed solution take a look to bavotasan page or just google.

Answer 4

In addition to checking the User-Agent header, you may also want to check the X-Wap-Profile and Profile headers, since some third-party browsers may not send a correct User-Agent header (they may be spoofing an IE or Firefox header). The order that I like to check the headers, when looking for mobile clients, is:

1. X-Wap-Profile
2. Profile
3. User-Agent
