然后利用下面的方法即可判断操作平台：
<?phpgetos();function getos(){ $ua = $_server['http_user_agent'];//这里只进行ios和android两个操作系统的判断，其他操作系统原理一样 if (strpos($ua, 'android') !== false) {//strpos()定位出第一次出现字符串的位置，这里定位为0 preg_match("/(?<=android )[\d\.]{1,}/", $ua, $version); echo 'platform:android os_version:'.$version[0]; } elseif (strpos($ua, 'iphone') !== false) { preg_match("/(?<=cpu iphone os )[\d\_]{1,}/", $ua, $version); echo 'platform:iphone os_version:'.str_replace('_', '.', $version[0]); } elseif (strpos($ua, 'ipad') !== false) { preg_match("/(?<=cpu os )[\d\_]{1,}/", $ua, $version); echo 'platform:ipad os_version:'.str_replace('_', '.', $version[0]); } }?>
以上就是php如何获取手机型号的详细内容。
