廢話不多說，上代碼
復制代碼 代碼如下:
<?php
//查詢禁止IP
$ip =$_SERVER['REMOTE_ADDR'];
$fileht=".htaccess2";
if(!file_exists($fileht))
file_put_contents($fileht,"");
$filehtarr=@file($fileht);
if(in_array($ip."\r\n",$filehtarr))
die("Warning:"."<br>"."Your IP address are forbided by some reason, IF you have any question Pls emill to [email protected]!");
//加入禁止IP
$time=time();
$fileforbid="log/forbidchk.dat";
if(file_exists($fileforbid)) {
if($time-filemtime($fileforbid)>60)
unlink($fileforbid);
else {
$fileforbidarr=@file($fileforbid);
if($ip==substr($fileforbidarr[0],0,strlen($ip))) {
if($time-substr($fileforbidarr[1],0,strlen($time))>600)
unlink($fileforbid);
elseif($fileforbidarr[2]>600) {
file_put_contents($fileht,$ip."\r\n",FILE_APPEND);
unlink($fileforbid);
} else {
$fileforbidarr[2]++;
file_put_contents($fileforbid,$fileforbidarr);
}
}
}
}
//防刷新
$str="";
$file="log/ipdate.dat";
if(!file_exists("log")&&!is_dir("log"))
mkdir("log",0777);
if(!file_exists($file))
file_put_contents($file,"");
$allowTime = 120;//防刷新時間
$allowNum=10;//防刷新次數
$uri=$_SERVER['REQUEST_URI'];
$checkip=md5($ip);
$checkuri=md5($uri);
$yesno=true;
$ipdate=@file($file);
foreach($ipdate as $k=>$v) {
$iptem=substr($v,0,32);
$uritem=substr($v,32,32);
$timetem=substr($v,64,10);
$numtem=substr($v,74);
if($time-$timetem<$allowTime) {
if($iptem!=$checkip)
$str.=$v;
else {
$yesno=false;
if($uritem!=$checkuri)
$str.=$iptem.$checkuri.$time."1\r\n";
elseif($numtem<$allowNum)

}
}
}
}

file_put_contents($file,$str);
?>
