PHP判断是手机端还是PC端 PHP判断是否是微信浏览器
本文实例为大家分享了PHP判断的两个实例,一是PHP判断是手机端还是PC端,二是PHP判断是否是微信浏览器,供大家参考,具体内容如下
1、判断是否是手机端
function isMobile() { // 如果有HTTP_X_WAP_PROFILE则一定是移动设备 if (isset($_SERVER['HTTP_X_WAP_PROFILE'])) { return true; } // 如果via信息含有wap则一定是移动设备,部分服务商会屏蔽该信息 if (isset($_SERVER['HTTP_VIA'])) { // 找不到为flase,否则为true return stristr($_SERVER['HTTP_VIA'], "wap") ? true : false; } // 脑残法,判断手机发送的客户端标志,兼容性有待提高。其中'MicroMessenger'是电脑微信 if (isset($_SERVER['HTTP_USER_AGENT'])) { $clientkeywords = array('nokia','sony','ericsson','mot','samsung','htc','sgh','lg','sharp','sie-','philips','panasonic','alcatel','lenovo','iphone','ipod','blackberry','meizu','android','netfront','symbian','ucweb','windowsce','palm','operamini','operamobi','openwave','nexusone','cldc','midp','wap','mobile','MicroMessenger'); // 从HTTP_USER_AGENT中查找手机浏览器的关键字 if (preg_match("/(" . implode('|', $clientkeywords) . ")/i", strtolower($_SERVER['HTTP_USER_AGENT']))) { return true; } } // 协议法,因为有可能不准确,放到最后判断 if (isset ($_SERVER['HTTP_ACCEPT'])) { // 如果只支持wml并且不支持html那一定是移动设备 // 如果支持wml和html但是wml在html之前则是移动设备 if ((strpos($_SERVER['HTTP_ACCEPT'], 'vnd.wap.wml') !== false) && (strpos($_SERVER['HTTP_ACCEPT'], 'text/html') === false || (strpos($_SERVER['HTTP_ACCEPT'], 'vnd.wap.wml') < strpos($_SERVER['HTTP_ACCEPT'], 'text/html')))) { return true; } } return false; }
2、判断是否是微信内置浏览器
function isWeixin() { if (strpos($_SERVER['HTTP_USER_AGENT'], 'MicroMessenger') !== false) { return true; } else { return false; } }
