For : the simplest reliable pattern is to record each request, then count how many records exist for that IP inside a chosen time window and redirect when the threshold is reached. 's suggestion to use a COUNT query is the right idea — the example below expands that into a safe, production-ready flow (IP validation, prepared statements, time-windowed count, and a server-side redirect). The sample uses PDO; adapt to mysqli if required.

<?php
$ip = getClientIp();

$pdo = new PDO('mysql:host=localhost;dbname=yourdb;charset=utf8mb4','dbuser','dbpass',[
    PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION,
]);

// record this attempt
$ins = $pdo->prepare('INSERT INTO ip (ip_address, created_at) VALUES (:ip, NOW())');
$ins->execute([':ip' => $ip]);

// count attempts in the last 24 hours (adjust interval as needed)
$stmt = $pdo->prepare(
  'SELECT COUNT(id) AS attempts FROM ip
   WHERE ip_address = :ip
     AND created_at >= DATE_SUB(NOW(), INTERVAL 24 HOUR)'
);
$stmt->execute([':ip' => $ip]);
$attempts = (int) $stmt->fetchColumn();

if ($attempts >= 5) {
    header('Location: /otherpage.php');
    exit;
}

// helper
function getClientIp() {
    foreach (['HTTP_CLIENT_IP','HTTP_X_FORWARDED_FOR','REMOTE_ADDR'] as $k) {
        if (!empty($_SERVER[$k])) {
            $ips = explode(',', $_SERVER[$k]);
            $ip = trim($ips[0]);
            if (filter_var($ip, FILTER_VALIDATE_IP)) return $ip;
        }
    }
    return null;
}

Notes and troubleshooting:

  • Ensure header() runs before any output (use output buffering if needed).
  • Table tips: id PK, ip_address VARCHAR(45), created_at DATETIME DEFAULT CURRENT_TIMESTAMP; index on (ip_address, created_at) for performance.
  • IPs can be shared or spoofed (proxies, NAT, IPv6); prefer tracking authenticated users where possible.
  • For high traffic, avoid counting many rows per request — consider an aggregated counter table (INSERT ... ON DUPLICATE KEY UPDATE) or an atomic increment to prevent race conditions.
  • Test with curl and check server logs; verify timezone, DB permissions, and that forwarded headers are handled securely.

The SQL query would be something like:

SELECT COUNT(*) FROM ip WHERE ip_address = 'x.x.x.x'

If it returns 5 or greater, then redirect them.

It's hard to know the exact code to use because you haven't told us if you're using a PHP framework, the library you're using to connect to the database server, etc.
