A. 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。
B. php判斷手機電腦並且進行跳轉
<?
$wap="手機地址";
$pc="pc地址";
ww($wap,$pc);
function ww($wap,$pc){
if(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'])){header("Location: $wap");
exit;
}else{header("Location: $pc");
exit;}
}
?>
C. PHP判斷客戶端是電腦還是手機
php判斷客戶端是手機的代碼，版權歸原作者，我只是搬運工。
function isMobile()
{
// 如果有HTTP_X_WAP_PROFILE則一定是移動設備
if (isset ($_SERVER['HTTP_X_WAP_PROFILE']))
{
return true;
}
// 如果via信息含有wap則一定是移動設備,部分服務商會屏蔽該信息
if (isset ($_SERVER['HTTP_VIA']))
{
// 找不到為flase,否則為true
return stristr($_SERVER['HTTP_VIA'], "wap") ? true : false;
}
// 腦殘法，判斷手機發送的客戶端標志,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'
);
// 從HTTP_USER_AGENT中查找手機瀏覽器的關鍵字
if (preg_match("/(" . implode('|', $clientkeywords) . ")/i", strtolower($_SERVER['HTTP_USER_AGENT'])))
{
return true;
}
}
// 協議法，因為有可能不準確，放到最後判斷
if (isset ($_SERVER['HTTP_ACCEPT']))
{
// 如果只支持wml並且不支持html那一定是移動設備
// 如果支持wml和html但是wml在html之前則是移動設備
if ((strpos($_SERVER['HTTP_ACCEPT'], 'vnd.wap.wml') !== false) && (strpos($_SERVER['HTTP_ACCEPT'], 'textml') === false || (strpos($_SERVER['HTTP_ACCEPT'], 'vnd.wap.wml') < strpos($_SERVER['HTTP_ACCEPT'], 'textml'))))
{
return true;
}
}
return false;
}
D. PHP怎樣識別手機與電腦的不同訪問
這個可以使用js來判斷一下UA就可以了。。
下面是一個手機訪問跳轉到手機版頁面的例子
(functionbrowserRedirect(){
varsUserAgent=navigator.userAgent.toLowerCase();
varbIsIpad=sUserAgent.match(/ipad/i)=='ipad';
varbIsIphone=sUserAgent.match(/iphoneos/i)=='iphoneos';
varbIsMidp=sUserAgent.match(/midp/i)=='midp';
varbIsUc7=sUserAgent.match(/rv:1.2.3.4/i)=='rv:1.2.3.4';
varbIsUc=sUserAgent.match(/ucweb/i)=='web';
varbIsCE=sUserAgent.match(/windowsce/i)=='windowsce';
varbIsWM=sUserAgent.match(/windowsmobile/i)=='windowsmobile';
varbIsAndroid=sUserAgent.match(/android/i)=='android';
if(bIsIpad||bIsIphone||bIsMidp||bIsUc7||bIsUc||bIsCE||bIsWM||bIsAndroid){
window.location.href='/wap/';
}
})();
E. php文件手機上怎麼打開
php文件屬於腳本語言文件,在正確瀏覽和使用他需要有相應的解析伺服器,現在主流是lamp架構或者lnmp架構的伺服器打開並解析php文件
在手機上打開你可以直接用手機里邊的文本編輯器打開就可以了,不過這樣打開你看到的會是php代碼,對於不懂編程的人來說看不懂,沒有什麼用
F. php程序有電腦版和手機版，怎讓手機訪問電腦版時自動識別是手機訪問跳到手機版去。電腦訪問手機版時自
你需要做一個手機頁，使用判斷語句，因為瀏覽器有一個自己的標示，如果是手機瀏覽器就跳到M頁，也就是手機頁面，這個你需要先在前端CSS做一個手機的匹配頁面，然後在將它用PHP實例化；還有你必須在頁面底部增加一個可切換，切換為電腦版，手機版的連接；
G. PHP代碼，怎麼設置根據電腦和手機顯示不同內容
構造一個判斷函數，匹配列出的agent就行，如果為真就輸出數字5或者之類的數據嘛，反之就輸出其他的，不會的話再問額解決
H. php如何判斷用戶通過手機wap訪問還是電腦直接訪問
PHP通過內置全局變數$_SERVER['HTTP_USER_AGENT']來獲取用戶信息，包括瀏覽器信息，操作系統等；判斷是否是手機還是電腦終端訪問，只需判斷他的$_SERVER['HTTP_USER_AGENT']信息是否存在手機終端類型即可。示例如下：
<?php
//1.獲取用戶瀏覽器信息 等；
$user_agent = $_SERVER['HTTP_USER_AGENT'];
//2.列舉常用手機終端類型
$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","iphone","ipod","jbrowser","kddi",
"kgt","kwc","lenovo","lg ","lg2","lg3","lg4","lg5","lg7","lg8","lg9","lg-","lge-","lge9","longcos","maemo",

"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",

"vk-","voda","voxtel","vx","wap","wellco","wig browser","wii","windows ce",
"wireless","xda","xde","zte");
foreach ($mobile_agents as $device) {
if (stristr($user_agent, $device)) {
//手機訪問
$is_mobile = true;
break;
}
}
//判斷手機標識是否為真
if($is_mobile){
echo "手機訪問！";
}else{
echo "電腦訪問！";
}
?>
回答不容易,希望能幫到您,滿意請幫忙採納一下，謝謝 !
