Question

我使用php进行移动检测，包括标头刷新。但是我想知道是否可以回应头标签和DOCTYPE。不幸的是，在检测到设备之前，页面似乎已加载。知道怎么解决吗？这是脚本，THX提前！

    <?php
$tablet_browser = 0;
$mobile_browser = 0;

if (preg_match('/(tablet|ipad|playbook)|(android(?!.*(mobi|opera mini)))/i', strtolower($_SERVER['HTTP_USER_AGENT']))) {
$tablet_browser++;
}

if (preg_match('/(up.browser|up.link|mmp|symbian|smartphone|midp|wap|phone|android|iemobile)/i', strtolower($_SERVER['HTTP_USER_AGENT']))) {
$mobile_browser++;
}

if ((strpos(strtolower($_SERVER['HTTP_ACCEPT']),'application/vnd.wap.xhtml+xml') > 0) or ((isset($_SERVER['HTTP_X_WAP_PROFILE']) or isset($_SERVER['        HTTP_PROFILE'])))) {
$mobile_browser++;
}

$mobile_ua = strtolower(substr($_SERVER['HTTP_USER_AGENT'], 0, 4));
$mobile_agents = array(
