看到别人写的,不知此函数是为什么服务的
function is_mobile() { $user_agent = $_server['http_user_agent']; $mobile_agents = array(240x320,acer,acoon,acs-,abacho,ahong,airness,alcatel,amoi,android,applewebkit/525,applewebkit/532,asus,audio,au-mic,avantogo,becker,benq,bilbo,bird,blackberry,blazer,bleu,cdm-,compal,coolpad,danger,dbtel,dopod,elaine,eric,etouch,fly ,fly_,fly-,go.web,goodaccess,gradiente,grundig,haier,hedy,hitachi,htc,huawei,hutchison,inno,ipad,ipaq,ipod,jbrowser,kddi,kgt,kwc,lenovo,lg ,lg2,lg3,lg4,lg5,lg7,lg8,lg9,lg-,lge-,lge9,longcos,maemo,mercator,meridian,micromax,midp,mini,mitsu,mmm,mmp,mobi,mot-,moto,nec-,netfront,newgen,nexian,nf-browser,nintendo,nitro,nokia,nook,novarra,obigo,palm,panasonic,pantech,philips,phone,pg-,playstation,pocket,pt-,qc-,qtek,rover,sagem,sama,samu,sanyo,samsung,sch-,scooter,sec-,sendo,sgh-,sharp,siemens,sie-,softbank,sony,spice,sprint,spv,symbian,tablet,talkabout,tcl-,teleca,telit,tianyu,tim-,toshiba,tsm,up.browser,utec,utstar,verykool,virgin,vk-,voda,voxtel,vx,wap,wellco,wig browser,wii,windows ce,wireless,xda,xde,zte); $is_mobile = false; foreach ($mobile_agents as $device) { if (stristr($user_agent, $device)) { $is_mobile = true; break; } } return $is_mobile; } $url = explode('/', $_server['request_uri']);
回复讨论(解决方案) 检测当前请求终端是否是手机或者平板等，笼统点讲就是检测是否是移动终端。
mobile [英][?mba?l][美][?mo?bl]
adj.可移动的; 行动自如的; 易变的; 流动性的;
n.风铃; 手机;
is_mobile 是否手机
通过http_user_agent 检测来源
那么问题又来了
下面这句的作用是啥,它是如何被解析的
$mobile_agents = array(240x320,acer,acoon,acs-,abacho,ahong,airness,alcatel,amoi,android,applewebkit/525,applewebkit/532,asus,audio,au-mic,avantogo,becker,benq,bilbo,bird,blackberry,blazer,bleu,cdm-,compal,coolpad,danger,dbtel,dopod,elaine,eric,etouch,fly ,fly_,fly-,go.web,goodaccess,gradiente,grundig,haier,hedy,hitachi,htc,huawei,hutchison,inno,ipad,ipaq,ipod,jbrowser,kddi,kgt,kwc,lenovo,lg ,lg2,lg3,lg4,lg5,lg7,lg8,lg9,lg-,lge-,lge9,longcos,maemo,mercator,meridian,micromax,midp,mini,mitsu,mmm,mmp,mobi,mot-,moto,nec-,netfront,newgen,nexian,nf-browser,nintendo,nitro,nokia,nook,novarra,obigo,palm,panasonic,pantech,philips,phone,pg-,playstation,pocket,pt-,qc-,qtek,rover,sagem,sama,samu,sanyo,samsung,sch-,scooter,sec-,sendo,sgh-,sharp,siemens,sie-,softbank,sony,spice,sprint,spv,symbian,tablet,talkabout,tcl-,teleca,telit,tianyu,tim-,toshiba,tsm,up.browser,utec,utstar,verykool,virgin,vk-,voda,voxtel,vx,wap,wellco,wig browser,wii,windows ce,wireless,xda,xde,zte);
foreach ($mobile_agents as $device) {
            if (stristr($user_agent, $device)) {
                $is_mobile = true;
                break;
            }
        }
遍历 $mobile_agents 数组，检查 $_server['http_user_agent'] 是否包含已知信息
