How to Obtain a Client\'s IP Address in Laravel 5 ?
Oct 20, 2024 am 08:37 AMObtain 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>
This function relies on Symfony's getClientIps method, which determines the client IP based on the following:
-
Trusted Proxies:
- If the IP is not a trusted proxy, the client IP is returned.
-
Forwarded Headers:
- If the Forwarded header is present and trusted, the for parameter is parsed for the client IP.
-
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>
This will provide the visitor's IP address, allowing you to implement IP-based functionality within your Laravel application.
