How to Obtain a Client's IP Address in Laravel 5 ?

Obtain the Client's IP Address in Laravel 5

In PHP, obtaining a client's IP address is straightforward using $_SERVER["REMOTE_ADDR"]. However, in Laravel, this technique returns the server IP rather than the visitor's IP.

Solution:

To accurately acquire the client IP address in Laravel, use:

<code class="php">Request::ip();</code>
Copy after login

This function relies on Symfony's getClientIps method, which determines the client IP based on the following:

  1. Trusted Proxies:

    • If the IP is not a trusted proxy, the client IP is returned.
  2. Forwarded Headers:

    • If the Forwarded header is present and trusted, the for parameter is parsed for the client IP.
  3. Client IP Headers:

    • If the Client-IP header is present and trusted, an array of IPs is extracted and the first valid IP is returned.

Fallback:

If none of the above headers are available or trusted, the IP obtained from $_SERVER["REMOTE_ADDR"] is used.

Example:

<code class="php">$clientIp = Request::ip();</code>
Copy after login

This will provide the visitor's IP address, allowing you to implement IP-based functionality within your Laravel application.
