在电商系统开发中,常见的一个功能就是:用户在没有登录的状态下将商品加入购物车,登录后自动将购物车数据同步上来。对此的解决办法我们一般都是使用COOKIE或者SESSION解决即可。其实也可以用获取客户端的mac地址作为唯一标识存入到数据库中,登录成功后再进行匹配。
获取服务器mac
<?php
/**
获取网卡的MAC地址原码;目前支持WIN/LINUX系统
获取机器网卡的物理(MAC)地址
**/
class GetmacAddr{
var $result = array(); // 返回带有MAC地址的字串数组
var $macAddr;
/*构造*/
function __construct($osType){
switch ( strtolower($osType) ){
case "unix": break;
case "solaris": break;
case "aix": break;
case "linux": {
$this->for_linux_os();
}break;
default: {
$this->for_windows_os();
}break;
}
$temp_array = array();
foreach($this->result as $value){
if(preg_match("/[0-9a-f][0-9a-f][:-]"."[0-9a-f][0-9a-f][:-]"."[0-9a-f][0-9a-f][:-]"."[0-9a-f][0-9a-f][:-]"."[0-9a-f][0-9a-f][:-]"."[0-9a-f][0-9a-f]/i",$value,
$temp_array ) ){
$this->macAddr = $temp_array[0];
break;
}
}
unset($temp_array);
return $this->macAddr;
}
/*linux系统中获取方法*/
function for_linux_os(){
@exec("ifconfig -a", $this->result);
return $this->result;
}
/*win系统中的获取方法*/
function for_windows_os(){
@exec("ipconfig /all", $this->result);
if ( $this->result ) {
return $this->result;
} else {
$ipconfig = $_SERVER["WINDIR"]."\system32\ipconfig.exe";
if(is_file($ipconfig)) {
@exec($ipconfig." /all", $this->result);
} else {
@exec($_SERVER["WINDIR"]."\system\ipconfig.exe /all", $this->result);
return $this->result;
}
}
}
}
?>
获取客户端mac地址:
@exec("arp -a",$array); //执行arp -a命令,结果放到数组$array中
foreach($array as $value){
//匹配结果放到数组$mac_array
if(strpos($value,$_SERVER["REMOTE_ADDR"]) && preg_match("/(:?[0-9A-F]{2}[:-]){5}[0-9A-F]{2}/i",$value,$mac_array)){
$mac = $mac_array[0];
break;
}
}
echo $mac;
注:客户端获取的mac不能在本机测试,只能用别的电脑访问才能输出
废话不多讲,直接上代码吧!
<?php
class MacAddr
{
public $returnArray = array();
public $macAddr;
function __contruct($os_type=null){
if(is_null($os_type)) $os_type = PHP_OS;
switch (strtolower($os_type)){
case "linux":
$this->forLinux();
break;
case "solaris":
break;
case "unix":
break;
case "aix":
break;
default:
$this->forWindows();
break;
}
$temp_array = array();
foreach($this->returnArray as $value ){
if(preg_match("/[0-9a-f][0-9a-f][:-]"."[0-9a-f][0-9a-f][:-]"."[0-9a-f][0-9a-f][:-]"."[0-9a-f][0-9a-f][:-]"."[0-9a-f][0-9a-f][:-]"."[0-9a-f][0-9a-f]/i", $value, $temp_array)){
$this->macAddr = $temp_array[0];
break;
}
}
unset($temp_array);
return $this->macAddr;
}
function forWindows(){
@exec("ipconfig /all", $this->returnArray);
if($this->returnArray)
return $this->returnArray;
else{
$ipconfig = $_SERVER["WINDIR"]."system32ipconfig.exe";
if (is_file($ipconfig))
@exec($ipconfig." /all", $this->returnArray);
else
@exec($_SERVER["WINDIR"]."systemipconfig.exe /all", $this->returnArray);
return $this->returnArray;
}
}
function forLinux(){
@exec("ifconfig -a", $this->returnArray);
return $this->returnArray;
}
}
$mac = new MacAddr(PHP_OS);
echo $mac->macAddr;
echo "<br />";
// 获取客户端
// linux
$command = "arp -a {$_SERVER['REMOTE_ADDR']}";
echo $command;
echo "<br />";
$result=`{$command}`;
// windows
$command = "nbtstat -a {$_SERVER['REMOTE_ADDR']}";
echo $command;
echo "<br />";
$result=`{$command}`;
print_r($result);
?>
获取服务端的逻辑没什么大问题,可能会存在权限问题。
获取客户端的时候,可能会比较慢,arp/nbstat命令执行会比较慢。

只适用于IE浏览器,而且会有告警提示,挺遗憾的。
