php获取访客代理信息设备类型、系统类型、浏览器信息

用php获取访问用户的设备代理信息，可以获取设备类型是移动端还是电脑端、设备的系统类型是windows还是linux等以及用的哪个浏览器甚至手机品牌等。

以下源码获取终端设备是移动端还是电脑端，系统类型，浏览器类型为例：

function getUserAgentInfo(){
	//获取user-agent
	$userAgent = empty($_SERVER['HTTP_USER_AGENT']) ? 'null' : $_SERVER['HTTP_USER_AGENT'];
	//判断访问设备类型
	$regex_match="/(nokia|iphone|android|motorola|^mot\-|softbank|foma|docomo|kddi|up\.browser|up\.link|KFAPWI|mobile|";
	$regex_match.="htc|dopod|ipad|blazer|netfront|helio|hosin|huawei|novarra|CoolPad|webos|techfaith|palmsource|";
	$regex_match.="blackberry|alcatel|amoi|ktouch|nexian|samsung|^sam\-|s[cg]h|^lge|ericsson|philips|sagem|wellcom|bunjalloo|maui|";
	$regex_match.="symbian|smartphone|midp|wap|phone|windows ce|Windows Phone|iemobile|^spice|^bird|^zte\-|longcos|pantech|gionee|^sie\-|portalmmm|";
	$regex_match.="jig\s browser|hiptop|^ucweb|^benq|haier|^lct|opera\s*mobi|opera\*mini|320x320|240x320|176x220";
	$regex_match.=")/i";
	$device = "PC";
	if(isset($_SERVER['HTTP_X_WAP_PROFILE']) or isset($_SERVER['HTTP_PROFILE']) or preg_match($regex_match, strtolower($userAgent))){
		$device = 'M';
	}
	//判断访问系统
	$system = "unknown";
	$ios_regex="/(iPhone OS|iPad)/i";
	if(false !== stripos($userAgent, 'Android')){
		$system = "Android";
	}else if(false !== stripos($userAgent, 'Windows Phone')){

	}else if(false !== stripos($userAgent, 'Linux')){
		$system = "Linux";
	}else if(false !== stripos($userAgent, 'Unix')){
		$system = "Unix";
	}

	//判断访问客户端
	$client = "unknown";
	$ie_regex="/(MSIE|Trident)/i";
	if(stripos($userAgent, 'MicroMessenger')){
		$client = "WeiXin";
	}else if(stripos($userAgent, 'AlipayClient')){

	}else if(stripos($userAgent, 'VivoBrowser')){
		$client = "Vivo";
	}else if(stripos($userAgent, 'MQQBrowser')){
		$client = "QQ浏览器移动端";
	}else if(stripos($userAgent, 'MQQBrowser')){
		$client = "QQ浏览器";
	}else if(stripos($userAgent, 'baiduboxapp')){
		$client = "百度app";
	}else if(stripos($userAgent, 'weibo')){
		$client = "WeiBo";
	}else if(stripos($userAgent, 'iqiyi')){

	}else if(stripos($userAgent, 'aweme')){
		$client = "抖音";
	}else if(stripos($userAgent, 'kdtUnion_iting')){
		$client = "喜马拉雅";
	}else if(stripos($userAgent, 'UCBrowser')){
		$client = "UC";
	}else if(stripos($userAgent, 'DingTalk')){

	}else if(stripos($userAgent, 'SamsungBrowser')){

	}else if(stripos($userAgent, 'HUAWEIEVA')){

	}else if(stripos($userAgent, 'NokiaBrowser')){

	}else if(stripos($userAgent, 'Opera')){

	}else if(stripos($userAgent, 'Firefox')){

	}else if(stripos($userAgent, 'Chrome')){

	}else if(stripos($userAgent, 'Safari')){
		$client = "苹果浏览器";
	}else if(preg_match($ie_regex, $userAgent)){
		$client = "IE";
	}
    return Array('device'=>$device, 'system'=>$system, 'client'=>$client);
