PHP簡單判斷當前使用的是什么瀏覽器

PHP簡單判斷當前使用的是什么瀏覽器，判斷瀏覽器類型的方法，方便統計網站訪問用戶使用瀏覽器的比例。

判斷瀏覽器類型方法

function userBrowser() { 
    $user_OSagent = $_SERVER['HTTP_USER_AGENT']; 
 
    if (strpos($user_OSagent, "Maxthon") && strpos($user_OSagent, "MSIE")) { 
        $visitor_browser = "Maxthon(Microsoft IE)"; 
    } elseif (strpos($user_OSagent, "Maxthon 2.0")) { 
        $visitor_browser = "Maxthon 2.0"; 
    } elseif (strpos($user_OSagent, "Maxthon")) { 
        $visitor_browser = "Maxthon"; 
    } elseif (strpos($user_OSagent, "MSIE 9.0")) { 
        $visitor_browser = "MSIE 9.0"; 
    } elseif (strpos($user_OSagent, "MSIE 8.0")) { 
        $visitor_browser = "MSIE 8.0"; 
    } elseif (strpos($user_OSagent, "MSIE 7.0")) { 
        $visitor_browser = "MSIE 7.0"; 
    } elseif (strpos($user_OSagent, "MSIE 6.0")) { 
        $visitor_browser = "MSIE 6.0"; 
    } elseif (strpos($user_OSagent, "MSIE 5.5")) { 
        $visitor_browser = "MSIE 5.5"; 
    } elseif (strpos($user_OSagent, "MSIE 5.0")) { 
        $visitor_browser = "MSIE 5.0"; 
    } elseif (strpos($user_OSagent, "MSIE 4.01")) { 
        $visitor_browser = "MSIE 4.01"; 
    } elseif (strpos($user_OSagent, "MSIE")) { 
        $visitor_browser = "MSIE 較高版本"; 
    } elseif (strpos($user_OSagent, "NetCaptor")) { 
        $visitor_browser = "NetCaptor"; 
    } elseif (strpos($user_OSagent, "Netscape")) { 
        $visitor_browser = "Netscape"; 
    } elseif (strpos($user_OSagent, "Chrome")) { 
        $visitor_browser = "Chrome"; 
    } elseif (strpos($user_OSagent, "Lynx")) { 
        $visitor_browser = "Lynx"; 
    } elseif (strpos($user_OSagent, "Opera")) { 
        $visitor_browser = "Opera"; 
    } elseif (strpos($user_OSagent, "Konqueror")) { 
        $visitor_browser = "Konqueror"; 
    } elseif (strpos($user_OSagent, "Mozilla/5.0")) { 
        $visitor_browser = "Mozilla"; 
    } elseif (strpos($user_OSagent, "Firefox")) { 
        $visitor_browser = "Firefox"; 
    } elseif (strpos($user_OSagent, "U")) { 
        $visitor_browser = "Firefox"; 
    } else { 
        $visitor_browser = "其它"; 
    } 
    return $visitor_browser; 
}

直接調用 userBrowser()

<?php echo "您現在使用的瀏覽器是：" . userBrowser();?>
