php判断终端是手机还是电脑的实现方法

这篇文章主要为大家详细介绍了php判断终端是手机还是电脑的实现方法，具有一定的参考价值，可以用来参考一下。

感兴趣的小伙伴，下面一起跟随四海网的小玲来看看吧！

代码一：

代码如下:

 
<?php
/*   四海网 www.q1010.com   */
 
function check_wap() { 
if (isset($_SERVER['HTTP_VIA'])) return true; 
if (isset($_SERVER['HTTP_X_NOKIA_CONNECTION_MODE'])) return true; 
if (isset($_SERVER['HTTP_X_UP_CALLING_LINE_ID'])) return true; 
if (strpos(strtoupper($_SERVER['HTTP_ACCEPT']),"VND.WAP.WML") > 0) { 
// Check whether the browser/gateway says it accepts WML. 
$br = "WML"; 
} else { 
$browser = isset($_SERVER['HTTP_USER_AGENT']) ? trim($_SERVER['HTTP_USER_AGENT']) : ''; 
if(empty($browser)) return true; 
$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-','160×160','176×220','240×240','240×320','320×240','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,$browser) || 
checkSubstrs($mobile_token_list,$browser); 
if($found_mobile) 
$br ="WML"; 
else $br = "WWW"; 
} 
if($br == "WML") { 
return true; 
} else { 
return false; 
} 
} 
function checkSubstrs($list,$str){ 
$flag = false; 
for($i=0;$i<count($list);$i++){ 
if(strpos($str,$list[$i]) > 0){ 
$flag = true; 
break; 
} 
} 
return $flag; 
} 
if(check_wap()){ 
echo "wap"; 
}else{ 
echo "web"; 
} 
?> 

代码二：
 

代码如下:

 
<?php
/*   四海网 www.q1010.com   */
 
header("Content-type:text/html;charset=utf-8"); 
function is_mobile(){ 
$user_agent = $_SERVER['HTTP_USER_AGENT']; 
$mobile_agents = Array("240x320","acer","acoon","acs-","abacho","ahong","airness","alcatel","amoi","android","anywhereyougo.com","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; 
} 
if(is_mobile()){ 
echo "手机"; 
}else{ 
echo "电脑"; 
}
