如何使用PHP判断访问来源呢?在支付等场景回经常用到,不需要再多余判断...
截图不完全,小弟直接上代码吧:
/**
* 判断是否移动端
* @return bool|string 返回标识
*/
protected function isMobile(){
//定义参数
$web = 'Web';
$mobile = 'Mobile';
$wx = 'WeiXin';
//判断是否是微信浏览器
if (strpos($_SERVER['HTTP_USER_AGENT'], 'MicroMessenger') !== false ){
return $wx;
}
//如果有HTTP_X_WAP_PROFILE则一定是移动设备
if (isset ($_SERVER['HTTP_X_WAP_PROFILE'])){
return $mobile;
}
//此条摘自TPM智能切换模板引擎,适合TPM开发
if(isset ($_SERVER['HTTP_CLIENT']) &&'PhoneClient'==$_SERVER['HTTP_CLIENT']){
return $mobile;
}
//如果via信息含有wap则一定是移动设备,部分服务商会屏蔽该信息
if (isset ($_SERVER['HTTP_VIA'])){
//找不到为flase,否则为true
return stristr($_SERVER['HTTP_VIA'], 'wap') ? true : false;
}
//判断手机发送的客户端标志,兼容性有待提高
if (isset ($_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'
);
//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 $mobile;
}
}
//协议法,因为有可能不准确,放到最后判断
if (isset ($_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 $mobile;
}
}
return $web;
}
各位看官,看在小弟直接上代码的份上点个赞再走呗!
