PHP判断访问来自于手机

仅供参考：

[code lang=”php”]
function wp_is_mobile() {
static $is_mobile;

if ( isset($is_mobile) )
return $is_mobile;

if ( empty($_SERVER[‘HTTP_USER_AGENT’]) ) {
$is_mobile = false;
} elseif ( strpos($_SERVER[‘HTTP_USER_AGENT’], ‘Mobile’) !== false
|| 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;
}
