A PHP-judging device is a phone/tablet code

When doing web development often need to use the mobile device to match the page, of course, you can make the site directly responsive, but if you do not want to do so, you can use PHP to determine the type of device, and then display the corresponding interface and content. Today share a method of using PHP to determine whether a device is a phone/tablet, based on WordPress (wp-includes/vars.php:125), suitable for most types of phone/tablet judgments: /** * Test If the current browser runs on a mobile device (smart phone, tablet, etc.) * * @staticvar BOOL $is _mobile * * @return BOOL */ function Wp_is_mobile () { static $is _mobile = null; if (Isset ($is _mobile)) { return $is _mobile; } if (Empty ($_server[' http_user_agent ')) { $is _mobile = false; } elseif (Strpos ($_server[' http_user_agent '), ' mobile ')!== false//Many Mobile devices (all IPhone, IPad, etc.) || Strpos ($_server[' http_user_agent '), ' Android ')!== false || Strpos ($_server[' http_user_agent '), ' silk/')!== false || Strpos ($_server[' http_user_agent '), ' Kindle ')!== false || Strpos ($_server[' http_user_agent '), ' BlackBerry ')!== false || Strpos ($_server[' http_user_agent '), ' Opera Mini ')!== false || Strpos ($_server[' http_user_agent '), ' Opera Mobi ')!== false) { $is _mobile = true; } else { $is _mobile = false; } return $is _mobile; } Copy Code
