做一個日誌文件用PHP

Question

我的註冊頁面看起來像這樣

$checkForUser = mysql_query("SELECT id FROM `users` WHERE `username`='{$posts['username']}' OR `email`='{$posts['email']}'"); 
$checkForUserRows = mysql_num_rows($checkForUser); 

$ip = VisitorIP(); 
$checkForIP = mysql_query("SELECT id FROM `users` WHERE `ip`='{$ip}'"); 
$checkForIPRows = mysql_num_rows($checkForIP); 

if ($checkForUserRows > 0) { 
    $error = "Username or email already registered!"; 
}else if ($checkForIPRows > 0) { 
    $error = "You may only have one account! This attempt has been logged. You will be banned! "; 

我想自動禁止其IP已經存在，則與以下錯誤$error = "You may only have one account! This attempt has been logged. You will be banned! ";

只寫與fwrite的日誌文件的帳戶http://php.net/manual/en/function.fwrite.php

要禁止ip，您需要在代碼的開頭執行ip檢查。你應該添加一個bool列到數據庫「禁止」。
