php判断用户是否手机访问代码

前端技术 2023/09/04 PHP

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：

$agent = check_wap();
if( $agent )
{
 header(\'Location: http://www.phpstudy.net\');
 exit;
}
// check if wap
function check_wap(){
 // 先检查是否为wap代理，准确度高
 if(stristr($_SERVER[\'HTTP_VIA\'],\"wap\")){
   return true;
 }
 // 检查浏览器是否接受 WML.
 elseif(strpos(strtoupper($_SERVER[\'HTTP_ACCEPT\']),\"VND.WAP.WML\") > 0){
   return true;
 }
 //检查USER_AGENT
 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\'])){
   return true;      
 }
 else{
   return false; 
 }
}

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：

function is_mobile_request() 
{ 
$_SERVER[\'ALL_HTTP\'] = isset($_SERVER[\'ALL_HTTP\']) ? $_SERVER[\'ALL_HTTP\'] : \'\'; 
$mobile_browser = \'0\'; 
if(preg_match(\'/(up.browser|up.link|mmp|symbian|smartphone|midp|wap|phone|iphone|ipad|ipod|android|xoom)/i\', strtolower($_SERVER[\'HTTP_USER_AGENT\']))) 
 $mobile_browser++; 
if((isset($_SERVER[\'HTTP_ACCEPT\'])) and (strpos(strtolower($_SERVER[\'HTTP_ACCEPT\']),\'application/vnd.wap.xhtml+xml\') !== false)) 
 $mobile_browser++; 
if(isset($_SERVER[\'HTTP_X_WAP_PROFILE\'])) 
 $mobile_browser++; 
if(isset($_SERVER[\'HTTP_PROFILE\'])) 
 $mobile_browser++; 
$mobile_ua = strtolower(substr($_SERVER[\'HTTP_USER_AGENT\'],0,4)); 
$mobile_agents = array( 
   \'w3c \',\'acs-\',\'alav\',\'alca\',\'amoi\',\'audi\',\'avan\',\'benq\',\'bird\',\'blac\', 
   \'blaz\',\'brew\',\'cell\',\'cldc\',\'cmd-\',\'dang\',\'doco\',\'eric\',\'hipt\',\'inno\', 
   \'ipaq\',\'java\',\'jigs\',\'kddi\',\'keji\',\'leno\',\'lg-c\',\'lg-d\',\'lg-g\',\'lge-\', 
   \'maui\',\'maxo\',\'midp\',\'mits\',\'mmef\',\'mobi\',\'mot-\',\'moto\',\'mwbp\',\'nec-\', 
   \'newt\',\'noki\',\'oper\',\'palm\',\'pana\',\'pant\',\'phil\',\'play\',\'port\',\'prox\', 
   \'qwap\',\'sage\',\'sams\',\'sany\',\'sch-\',\'sec-\',\'send\',\'seri\',\'sgh-\',\'shar\', 
   \'sie-\',\'siem\',\'smal\',\'smar\',\'sony\',\'sph-\',\'symb\',\'t-mo\',\'teli\',\'tim-\', 
   \'tosh\',\'tsm-\',\'upg1\',\'upsi\',\'vk-v\',\'voda\',\'wap-\',\'wapa\',\'wapi\',\'wapp\', 
   \'wapr\',\'webc\',\'winw\',\'winw\',\'xda\',\'xda-\' 
   ); 
if(in_array($mobile_ua, $mobile_agents)) 
 $mobile_browser++; 
if(strpos(strtolower($_SERVER[\'ALL_HTTP\']), \'operamini\') !== false) 
 $mobile_browser++; 
// Pre-final check to reset everything if the user is on Windows 
if(strpos(strtolower($_SERVER[\'HTTP_USER_AGENT\']), \'windows\') !== false) 
 $mobile_browser=0; 
// But WP7 is also Windows, with a slightly different characteristic 
if(strpos(strtolower($_SERVER[\'HTTP_USER_AGENT\']), \'windows phone\') !== false) 
 $mobile_browser++; 
if($mobile_browser>0) 
 return true; 
else
 return false; 
}

再给大家分享一个个人使用的

function isPhone() {
  // 如果有HTTP_X_WAP_PROFILE则一定是移动设备
  if (isset($_SERVER[\'HTTP_X_WAP_PROFILE\'])) {
    return true;
  }
  //如果via信息含有wap则一定是移动设备,部分服务商会屏蔽该信息
  if (isset($_SERVER[\'HTTP_VIA\'])) {
    //找不到为flase,否则为true
    if(stristr($_SERVER[\'HTTP_VIA\'], \"wap\"))
    {
      return true;
    }
  }
  //脑残法，判断手机发送的客户端标志,兼容性有待提高
  if (isset($_SERVER[\'HTTP_USER_AGENT\'])) {
    $clientkeywords = array (
      \'nokia\',
      \'sony\',
      \'ericsson\',
      \'mot\',
      \'samsung\',
      \'htc\',
      \'sgh\',
      \'lg\',
      \'sharp\',
      \'sie-\',
      \'philips\',
      \'panasonic\',
      \'alcatel\',
      \'lenovo\',
      \'iphone\',
      \'ipod\',
      \'blackberry\',
      \'meizu\',
      \'android\',
      \'netfront\',
      \'symbian\',
      \'ucweb\',
      \'windowsce\',
      \'palm\',
      \'operamini\',
      \'operamobi\',
      \'openwave\',
      \'nexusone\',
      \'cldc\',
      \'midp\',
      \'wap\',
      \'mobile\',
      \'phone\',
    );
    // 从HTTP_USER_AGENT中查找手机浏览器的关键字
    if (preg_match(\"/(\" . implode(\'|\', $clientkeywords) . \")/i\", strtolower($_SERVER[\'HTTP_USER_AGENT\']))) {
      return true;
    }
  }
  //协议法，因为有可能不准确，放到最后判断
  if (isset($_SERVER[\'HTTP_ACCEPT\'])) {
    // 如果只支持wml并且不支持html那一定是移动设备
    // 如果支持wml和html但是wml在html之前则是移动设备
    if ((strpos($_SERVER[\'HTTP_ACCEPT\'], \'vnd.wap.wml\') !== false) && (strpos($_SERVER[\'HTTP_ACCEPT\'], \'text/html\') === false || (strpos($_SERVER[\'HTTP_ACCEPT\'], \'vnd.wap.wml\') < strpos($_SERVER[\'HTTP_ACCEPT\'], \'text/html\')))) {
      return true;
    }
  }
  return false;
}
