PHP CodeBase: 判断用户是否手机访问(转)

随着移动设备的普及，网站也会迎来越来越多移动设备的访问。用适应PC的页面，很多时候对手机用户不友好，那么有些时候，我们需要判断用户是否用手机访问，如果是手机的话，就跳转到指定的手机友好页面。这里就介绍一下，如何判断用户是否用手机访问。

自定义的函数如下：

`01`	`$agent` `= check_wap();`

`02`	`if(` `$agent` `)`

03 {

`04`	`header('Location: http://www.nowamagic.net');`

05 exit;

06 }

07

`08`	`// check if wap`

`09`	`function` `check_wap(){`

`10`	`// 先检查是否为wap代理，准确度高`

`11`	`if(stristr($_SERVER['HTTP_VIA'],"wap")){`

`12`	`return` `true;`

13 }

`14`	`// 检查浏览器是否接受 WML.`

`15`	`elseif(strpos(strtoupper($_SERVER['HTTP_ACCEPT']),"VND.WAP.WML") > 0){`

`16`	`return` `true;`

17 }

`18`	`//检查USER_AGENT`

19 elseif(preg_match('/(blackberry|configuration\/cldc|hp |hp-|htc |htc_|htc-|iemobile|kindle|midp|mmp|motorola|mobile|nokia|opera mini|opera |Googlebot-Mobile|YahooSeeker\/M1A1-R2D2|android|iphone|ipod|mobi|palm|palmos|pocket|portalmmm|ppc;|smartphone|sonyericsson|sqh|spv|symbian|treo|up.browser|up.link|vodafone|windows ce|xda |xda_)/i', $_SERVER['HTTP_USER_AGENT'])){

`20`	`return` `true;`

21 }

22 else{

`23`	`return` `false;`

24 }

25 }

再来一个从PHP框架剥离的判断是否为手机移动终端的函数：

view source

print ?

`01`	`function` `is_mobile_request()`

02 {

`03`	`$_SERVER['ALL_HTTP'] = isset($_SERVER['ALL_HTTP']) ?$_SERVER['ALL_HTTP'] :` `'';`

`04`	`$mobile_browser` `=` `'0';`

`05`	`if(preg_match('/(up.browser\|up.link\|mmp\|symbian\|smartphone\|midp\|wap\|phone\|iphone\|ipad\|ipod\|android\|xoom)/i',strtolower($_SERVER['HTTP_USER_AGENT'])))`

`06`	`$mobile_browser++;`

`07`	`if((isset($_SERVER['HTTP_ACCEPT']))` `and(strpos(strtolower($_SERVER['HTTP_ACCEPT']),'application/vnd.wap.xhtml+xml') !== false))`

`08`	`$mobile_browser++;`

`09`	`if(isset($_SERVER['HTTP_X_WAP_PROFILE']))`

`10`	`$mobile_browser++;`

`11`	`if(isset($_SERVER['HTTP_PROFILE']))`

`12`	`$mobile_browser++;`

`13`	`$mobile_ua` `=` `strtolower(substr($_SERVER['HTTP_USER_AGENT'],0,4));`

`14`	`$mobile_agents` `=` `array(`

`15`	`'w3c ','acs-','alav','alca','amoi','audi','avan','benq','bird','blac',`

`16`	`'blaz','brew','cell','cldc','cmd-','dang','doco','eric','hipt','inno',`

`17`	`'ipaq','java','jigs','kddi','keji','leno','lg-c','lg-d','lg-g','lge-',`

`18`	`'maui','maxo','midp','mits','mmef','mobi','mot-','moto','mwbp','nec-',`

`19`	`'newt','noki','oper','palm','pana','pant','phil','play','port','prox',`

`20`	`'qwap','sage','sams','sany','sch-','sec-','send','seri','sgh-','shar',`

`21`	`'sie-','siem','smal','smar','sony','sph-','symb','t-mo','teli','tim-',`

`22`	`'tosh','tsm-','upg1','upsi','vk-v','voda','wap-','wapa','wapi','wapp',`

`23`	`'wapr','webc','winw','winw','xda','xda-'`

24 );

`25`	`if(in_array($mobile_ua,` `$mobile_agents))`

`26`	`$mobile_browser++;`

`27`	`if(strpos(strtolower($_SERVER['ALL_HTTP']),` `'operamini') !== false)`

`28`	`$mobile_browser++;`

`29`	`// Pre-final check to reset everything if the user is on Windows`

`30`	`if(strpos(strtolower($_SERVER['HTTP_USER_AGENT']),` `'windows') !== false)`

`31`	`$mobile_browser=0;`

`32`	`// But WP7 is also Windows, with a slightly different characteristic`

`33`	`if(strpos(strtolower($_SERVER['HTTP_USER_AGENT']),` `'windows phone') !== false)`

`34`	`$mobile_browser++;`

`35`	`if($mobile_browser>0)`

`36`	`return` `true;`

37 else

`38`	`return` `false;`

39 }
