PHP to determine whether to access the phone

Sometimes we need to determine whether the access is from the phone or the PC side, PHP can be very convenient to judge.

$_server[' http_user_agent '] contains the header information (header) of the access, according to which we can make a judgment .

function IsMobile ()

{

$useragent =isset ($_server[' http_user_agent ')? $_server[' http_user_agent ': ';

$useragent _commentsblock=preg_match (' |\ (. *?\) | ', $useragent, $matches) >0? $matches [0]: ';

function Checksubstrs ($substrs, $text)

{

foreach ($substrs as $substr)

if (False!==strpos ($text, $substr)) {

return true;

}

return false;

}

$mobile _os_list=array (' Google Wireless transcoder ', ' Windows CE ', ' windowsce ', ' Symbian ', ' Android ', ' armv6l ' , ' armv5 ', ' Mobile ', ' CentOS ', ' mowser ', ' AvantGo ', ' Opera Mobi ', ' J2ME/MIDP ', ' Smartphone ', ' go.web ', ' Palm ', ' IPAQ ');

$mobile _token_list=array (' PROFILE/MIDP ', ' configuration/cldc-', ' 160x160 ', ' 176x220 ', ' 240x240 ', ' 240x320 ' , ' A ', ' up. Browser ', ' up. Link ', ' SymbianOS ', ' PalmOS ', ' PocketPC ', ' SonyEricsson ', ' Nokia ', ' BlackBerry ', ' Vodafone ', ' BenQ ', ' novarra-vision ', ' Iris ', ' NetFront ', ' htc_ ', ' Xda_ ', ' samsung-sgh ', ' Wapaka ', ' DoCoMo ', ' iPhone ', ' iPod ';

$found _mobile=checksubstrs ($mobile _os_list, $useragent _commentsblock) | |

checksubstrs ($mobile _token_list, $useragent);

if ($found _mobile)

{

return true;

}

Else

{

return false;

}

}

This method can be modified to determine whether a browser is opened.
