判断浏览器类型实例:

<?php  
    if(strpos($_SERVER["HTTP_USER_AGENT"],"MSIE 8.0"))  
    echo "Internet Explorer 8.0";  
    else if(strpos($_SERVER["HTTP_USER_AGENT"],"MSIE 7.0"))  
    echo "Internet Explorer 7.0";  
    else if(strpos($_SERVER["HTTP_USER_AGENT"],"MSIE 6.0"))  
    echo "Internet Explorer 6.0";  
    else if(strpos($_SERVER["HTTP_USER_AGENT"],"Firefox/3"))  
    echo "Firefox 3";  
    else if(strpos($_SERVER["HTTP_USER_AGENT"],"Firefox/2"))  
    echo "Firefox 2";  
    else if(strpos($_SERVER["HTTP_USER_AGENT"],"Chrome"))  
    echo "Google Chrome";  
    else if(strpos($_SERVER["HTTP_USER_AGENT"],"Safari"))  
    echo "Safari";  
    else if(strpos($_SERVER["HTTP_USER_AGENT"],"Opera"))  
    echo "Opera";  
    else echo $_SERVER["HTTP_USER_AGENT"];  
?>  

判断浏览器语言的具体实例:

<?php  
    $lang = substr($_SERVER['HTTP_ACCEPT_LANGUAGE'], 0, 4); //只取前 4 位，这样只判断最优先的语言。如果取前 5 位，可能出现 en,zh 的情况，影响判断。  
    if (preg_match("/zh-c/i", $lang))  
    echo "简体中文";  
    else if (preg_match("/zh/i", $lang))  
    echo "繁體中文";  
    else if (preg_match("/en/i", $lang))  
    echo "English";  
    else if (preg_match("/fr/i", $lang))  
    echo "French";  
    else if (preg_match("/de/i", $lang))  
    echo "German";  
    else if (preg_match("/jp/i", $lang))  
    echo "Japanese";  
    else if (preg_match("/ko/i", $lang))  
    echo "Korean";  
    else if (preg_match("/es/i", $lang))  
    echo "Spanish";  
    else if (preg_match("/sv/i", $lang))  
    echo "Swedish";  
    else echo $_SERVER["HTTP_ACCEPT_LANGUAGE"];  
?>  

PHP 自定义函数判断浏览器语音：

function getPreferredLanguage() {  
    $langs = array();  
    if (isset($_SERVER['HTTP_ACCEPT_LANGUAGE'])) {  
        // break up string into pieces (languages and q factors)  
        preg_match_all('/([a-z]{1,8}(-[a-z]{1,8})?)s*(;s*qs*=s*(1|0.[0-9]+))?/i',  
                $_SERVER['HTTP_ACCEPT_LANGUAGE'], $lang_parse);  
        if (count($lang_parse[1])) {  
            // create a list like "en" => 0.8  
            $langs = array_combine($lang_parse[1], $lang_parse[4]);  
            // set default to 1 for any without q factor  
            foreach ($langs as $lang => $val) {  
                if ($val === '') $langs[$lang] = 1;  
            }  
            // sort list based on value  
            arsort($langs, SORT_NUMERIC);  
        }  
    }  
    //extract most important (first)  
    foreach ($langs as $lang => $val) { break; }  
    //if complex language simplify it  
    if (stristr($lang,"-")) {$tmp = explode("-",$lang); $lang = $tmp[0]; }  
    return $lang;  
}
