PHP与JS屏蔽电脑端代码

JS屏蔽电脑端代码，屏蔽win电脑端与苹果笔记本Mac（屏蔽后会跳转指定网址），感觉这个比PHP屏蔽好用一点（因为一般别人在F12控制台伪造了UA 也会被屏蔽）

<script type="text/javascript"> 
    var system ={ 
        win : false, 
        mac : false, 
        xll : false
    };
    var p = navigator.platform; 
    system.win = p.indexOf("Win") == 0; 
    system.mac = p.indexOf("Mac") == 0; 
    system.x11 = (p == "X11") || (p.indexOf("Linux") == 0);
    if(system.win||system.mac||system.xll){   
        window.location.href="https://baidu.com"; //跳转地址
    }</script>

话不多说了，上PHP屏蔽代码

<?php
function strexists2($string, $find) { return !(strpos($string, $find) === false); }
function deep_in_array2($value, $array) { 
        foreach($array as $item) {   
            if(!is_array($item)) {   
              if (strpos($value, $item) !== false) {   
                    return true;  
                } else {  continue; } }   
                
            if(in_array($value, $item)) {  
                return true;      
            } else if(deep_in_array($value, $item)) {  
                return true;      
            }  
        }   return false;   }			
			
function mobile() {
	$useragent = strtolower($_SERVER['HTTP_USER_AGENT']);
	$ualist = array('android', 'midp', 'nokia', 'mobile', 'iphone', 'ipod', 'blackberry', 'windows phone');
	if((deep_in_array2($useragent, $ualist) || strexists2($_SERVER['HTTP_ACCEPT'], "VND.WAP") || strexists2($_SERVER['HTTP_VIA'],"wap")))
if(strpos($useragent,'iphone')!==false||strpos($useragent,'ipod')!==false) return '苹果'; else return '安卓';
	else
  return '电脑'; }
 
if(mobile()=='电脑'){ exit(header("location:https://baidu.com")); } //跳转地址
