php判斷移動端
functionisMobile()
{
//如果有HTTP_X_WAP_PROFILE則一定是移動設備
if(isset($_SERVER['HTTP_X_WAP_PROFILE']))
{
returntrue;
}
//如果HTTP_VIA含有wap則一定是移動設備,部分服務商會屏蔽該信息
if(isset($_SERVER['HTTP_VIA']))
{
//找不到為flase,否則為true
returnstristr($_SERVER['HTTP_VIA'],"wap")?true:false;
}
// 判斷手機發送的客戶端標志
if(isset($_SERVER['HTTP_USER_AGENT']))
{
$clientkeywords=array('nokia',

'ericsson',
'mot',
'samsung',
'htc',

returntrue;
}
}
//協議法，因為有可能不準確，放到最後判斷
if(isset($_SERVER['HTTP_ACCEPT']))
{
//如果只支持wml並且不支持html那一定是移動設備
//如果支持wml和html但是wml在html之前則是移動設備

⑵ PHP如何識別是電腦端或手機移動端訪問網站
用css來判斷當前頁面的寬度和高度，現在pc的解析度最低都在1200*768以上，iPad pro的寬度為1024px，當寬度大於1100px以上，都可以認為當前訪問端為pc，一般iPad的寬度為768px，iPhone X的寬度為375px；所以當寬度低於800以下的，都視為手機移動端，現在的pc和手機自適應頁面都是按照這個來區分的。
⑶ php怎麼判斷訪問端是移動端還是pc端
2002年到2010年這之間php異軍突起的主要原因，是因為互聯網尤其是pc端的崛起，那時快速迭代開發，是所有中小企業最大的需求，管你什麼介面速度，運行效率，單線程還是多線程庫多還是庫少，只要能在短時間內把網站搞起來就行。
直到2010年以後移動端的出現app的使用大幅度超過pc端，前後端開始逐步分離，php本身可以嵌入html代碼就不再是特別大的優勢了，尤其php對進程線程協程的支持不夠使得一些app性能需求無法滿足，因此php更多開始和其他語言混用，甚至被其他像go，python這樣的語言壓制並搶占份額。
雖然說總體上我對php的發展還是樂觀的，畢竟社區，體量，易用性擺在那裡，尤其是php8即將誕生。但是隨著移動互聯網逐漸走向尾聲，app開發對性能要求的更高php在某些方面的劣勢也越來越明顯。因此對於php的培訓減少並不奇怪。
⑷ php如何判斷頁面是手機端還是pc端
PHP 有個手機檢測的庫很出名啊 Mobile-Detect
地址：https://packagist.org/packages/mobiledetect/mobiledetectlib
或者
<?php
functionisMobile(){
$useragent=isset($_SERVER['HTTP_USER_AGENT'])?$_SERVER['HTTP_USER_AGENT']:'';
$useragent_commentsblock=preg_match('|(.*?)|',$useragent,$matches)>0?$matches[0]:'';
functionCheckSubstrs($substrs,$text){
foreach($substrsas$substr){
if(false!==strpos($text,$substr)){
returntrue;
}else{
returnfalse;
}
}
}
$mobile_os_list=array('GoogleWirelessTranscoder','WindowsCE','WindowsCE','Symbian','Android','armv6l','armv5','Mobile','CentOS','mowser','AvantGo','OperaMobi','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,$useragent_commentsblock)||CheckSubstrs($mobile_token_list,$useragent);
if($found_mobile){
returntrue;
}else{
returnfalse;
}
}
if(isMobile())
echo'phone';
else
echo'pc';
?>
⑸ php判斷用戶是否使用手機設備
php判斷用戶是否使用手機第一步：如果你和我一樣使用的是wordpress，那就復制到主題的 function.php 文件//判斷是否屬手機 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; } 第二步：if 語句if( is_mobile() ){ echo "您使用的是手機"; }
⑹ ThinkPHP中判斷是手機端還是電腦端訪問的方法
一般是通過訪問的時候請求來源的header頭文件信息來進行判斷的，譬如Android的手機訪問的話一般都會在hedear頭信息裡面帶上Android這樣的信息，同理Iphone、windows phone都會帶。
