復(fù)制代碼 代碼如下:
<?php

 $useragent=isset($_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; 
 }

 $found_mobile=CheckSubstrs($mobile_os_list,$useragent_commentsblock) || 
     CheckSubstrs($mobile_token_list,$useragent); 

 if ($found_mobile){ 
  return true; 
 }else{ 
  return false; 
 } 
}
if (isMobile())
 echo '手機(jī)登錄m.jb51.com';
else
 echo '電腦登錄www.jb51.com';
