在做网站时,有些网页我们只希望通过手机可以访问,而PC端不可以,这时候,我们就需要判断浏览器的类型。判断浏览器类型的方法有很多,有通过JS实现的,也有通过PHP实现的。下面我们给大家介绍一种通过PHP来判断浏览器类型的方法。
<?php function check_wap() { if (isset($_SERVER['HTTP_VIA'])) return true; if (isset($_SERVER['HTTP_X_NOKIA_CONNECTION_MODE'])) return true; if (isset($_SERVER['HTTP_X_UP_CALLING_LINE_ID'])) return true; if (strpos(strtoupper($_SERVER['HTTP_ACCEPT']),"VND.WAP.WML") > 0) { // Check whether the browser/gateway says it accepts WML. $br = "WML"; } else { $browser = isset($_SERVER['HTTP_USER_AGENT']) ? trim($_SERVER['HTTP_USER_AGENT']) : ''; if(empty($browser)) return true; $mobile_os_list=array('Google Wireless Transcoder','Windows CE','WindowsCE','Symbian','Android','armv6l','armv5','Mobile','CentOS','mowser','AvantGo','Opera Mobi','J2ME/MIDP','Smartphone','Go.Web','Palm','iPAQ'); $mobile_token_list=array('Profile/MIDP','Configuration/CLDC-','160×160','176×220','240×240','240×320','320×240','UP.Browser','UP.Link','SymbianOS','PalmOS','PocketPC','SonyEricsson','Nokia','BlackBerry','Vodafone','BenQ','Novarra-Vision','Iris','NetFront','HTC_','Xda_','SAMSUNG-SGH','Wapaka','DoCoMo','iPhone','iPod'); $found_mobile=checkSubstrs($mobile_os_list,$browser) || checkSubstrs($mobile_token_list,$browser); if($found_mobile) $br ="WML"; else $br = "WWW"; } if($br == "WML") { return true; } else { return false; } } function checkSubstrs($list,$str){ $flag = false; for($i=0;$i<count ($list);$i++){ if(strpos($str,$list[$i]) > 0){ $flag = true; break; } } return $flag; } if(check_wap()){ echo "<h1>You are using mobile browser</h1>"; }else{ echo "<h1>You are using PC browser</h1>"; } ?>
