Как определить, что клиент зашел на сайт через браузер iPhone?

searching on the net there are two common ways of achieving this. My favorite though is in PHP its just so clean? wow. :D

In PHP you can write

<?php function isIphone($user_agent=NULL) { if(!isset($user_agent)) { $user_agent = isset($_SERVER[′HTTP_USER_AGENT′]) ? $_SERVER[′HTTP_USER_AGENT′] : ′′; } return (strpos($user_agent, ′iPhone′) !== FALSE); } if(isIphone()) { header(′Location: http://www.yourwebsite.com/phone′); exit(); } // ...THE REST OF YOUR CODE HERE ?>

and in javascript you can write

var agent = navigator.userAgent; var isIphone = ((agent.indexOf(′iPhone′) != -1) || (agent.indexOf(′iPod′) != -1)) ; if (isIphone) { window.location.href = ′http://www.yourwebsite.com/phone′; }
