判斷使用者是PC還是移動端的php代碼

先我們來看看一段用php如何識別使用者是通過 PC、iPad 還是手機來訪問網站？

<?php
$uAgent = $_SERVER['HTTP_USER_AGENT'];
$osPat = "mozilla|m3gate|winwap|openwave|Windows NT|Windows 3.1|95|Blackcomb|98|ME|XWindow|ubuntu|Longhorn|AIX|Linux|AmigaOS|BEOS|HP-UX|OpenBSD|FreeBSD|NetBSD|OS\/2|OSF1|SUN";
if(preg_match("/($osPat)/i", $uAgent ))
{
    echo "來著PC訪問";
}
else
{
    echo "其他終端訪問";
}
 
?>

如何判斷訪問網站的機器類型-如何判斷ipad

如何判斷是否是 iPad 瀏覽器呢，關鍵是看它的 User Agent 中是否有 iPad。iPad 使用的是 Safari Mobile 瀏覽器，他的的 User Agent 是：

Mozilla/5.0 (iPad; U; CPU OS 3_2 like Mac OS X; en-us) AppleWebKit/531.21.10 (KHTML, like Gecko) Version/4.0.4 Mobile/7B334b Safari/531.21.10

function is_iPad(){        
 [object Object] [object Object] [object Object]var ua = navigator.userAgent.toLowerCase();
 [object Object] [object Object] [object Object]if(ua.match(/iPad/i)=="ipad") {                
 [object Object] [object Object] [object Object] [object Object] [object Object] [object Object]return true;
 [object Object] [object Object] [object Object]} else {
 [object Object] [object Object] [object Object] [object Object] [object Object] [object Object]return false;
 [object Object] [object Object] [object Object]}
}


$is_iPad = (bool) strpos($_SERVER['HTTP_USER_AGENT'],'iPad');

RewriteCond %{HTTP_USER_AGENT} ^.*iPad.*$
RewriteRule ^(.*)$ http://ipad.fairyfish.net [R=301]
