php判斷客戶端是pc還是行動裝置的方法：根據php的$_SERVER['HTTP_USER_AGENT']中的各種瀏覽器存取時所包含各個瀏覽器特定的字串來判斷是屬於PC還是移動端。

php怎麼判斷客戶端是pc還是行動設備

本文操作環境：windows10系統、php 7.3、thinkpad t480電腦。

具體方法如下：

方法一：

/**

#方法二：

<?php
function isMobile()
{ 
    // 如果有HTTP_X_WAP_PROFILE则一定是移动设备
    if (isset ($_SERVER[&#39;HTTP_X_WAP_PROFILE&#39;]))
    {
        return true;
    } 
    // 如果via信息含有wap则一定是移动设备,部分服务商会屏蔽该信息
    if (isset ($_SERVER[&#39;HTTP_VIA&#39;]))
    { 
        // 找不到为flase,否则为true
        return stristr($_SERVER[&#39;HTTP_VIA&#39;], "wap") ? true : false;
    } 
    // 脑残法，判断手机发送的客户端标志,兼容性有待提高
    if (isset ($_SERVER[&#39;HTTP_USER_AGENT&#39;]))
    {
        $clientkeywords = array (&#39;nokia&#39;,

            &#39;wap&#39;,
            &#39;mobile&#39;
            ); 
        // 从HTTP_USER_AGENT中查找手机浏览器的关键字
        if (preg_match("/(" . implode(&#39;|&#39;, $clientkeywords) . ")/i", strtolower($_SERVER[&#39;HTTP_USER_AGENT&#39;])))
        {
            return true;
        } 
    } 
    // 协议法，因为有可能不准确，放到最后判断
    if (isset ($_SERVER[&#39;HTTP_ACCEPT&#39;]))
    { 
        // 如果只支持wml并且不支持html那一定是移动设备
        // 如果支持wml和html但是wml在html之前则是移动设备
        if ((strpos($_SERVER[&#39;HTTP_ACCEPT&#39;], &#39;vnd.wap.wml&#39;) !== false) && (strpos($_SERVER[&#39;HTTP_ACCEPT&#39;], &#39;text/html&#39;) === false || (strpos($_SERVER[&#39;HTTP_ACCEPT&#39;], &#39;vnd.wap.wml&#39;) < strpos($_SERVER[&#39;HTTP_ACCEPT&#39;], &#39;text/html&#39;))))
        {
            return true;
        } 
    } 
    return false;
} 
?>

第一種方法親測可用

呼叫函數：

if(!checkmobile())

{}

else{}

如果為手機，則。。。否則。
