PHP文件编辑问题

Question

我最近一直在使用IIS和PHP，但不能编辑文件。我向IIS_IUSRS授予了编辑wwwroot文件的权限，但这似乎没有做任何事情。我仍然收到以下警告：

Thanks for your request, *My IP Here* The robot moved forward. Warning: fopen(Ips.txt): failed to open stream: Permission denied in C:\inetpub\wwwroot\CMD.php on line 20 Unable to open file, Ips.txtPermission denied in C:\inetpub\wwwroot\CMD.php on line 20 Unable to open file, Ips.txt

如果我理解正确的话，这意味着wwwroot不能进行php编辑。下面是我的代码：

<?php
$cmd=$_GET["cmd"];
$ip=$_SERVER['REMOTE_ADDR'];
if($cmd=="Forward") {
//insert forward code here.
    echo "Thanks for your request, ".$ip." The robot moved forward.";

} else if($cmd=="Backward") {
//insert backwards code here.
    echo "Thanks for your request, ".$ip." The robot moved backwards.";
} else if($cmd=="Left") {
//insert left code here.
    echo "Thanks for your request, ".$ip." The robot moved left.";
} else if($cmd=="Right") {
//insert right code here.
    echo "Thanks for your request, ".$ip." The robot moved right.";
} else {
    echo "Got invalid command: ".$cmd." From IP: ".$ip;
}
$ipfile = fopen("C:/inetpub/wwwroot/Ips.txt",'w') or exit("Unable to open file, Ips.txt");
if(!strpos(file_get_contents("C:/inetpub/wwwroot/Ips.txt"),$ip)) {
    fwrite($ipfile,$ip);
}
echo "\nYour IP has been logged for security purposes.";
fclose($ipfile);
$log=fopen("C:/inetpub/wwwroot/Logs.txt",'w') or exit("Unable to open file, Logs.txt");
fwrite($log,"Got command, ".$cmd." from a computer at the adress, ".$ip);
fclose($log);
?>

我已经查看了很长一段时间，也发现了类似的情况，但解决方案要么是找不到，要么是关于不正确的IIS文件权限。

我弄清楚了，原来IPs.txt不知何故失去了用户编辑的权限，我添加了权限，并解决了这个问题，谢谢你的帮助！
