[SOLVED] Detecting properly formatted IP address

[Brandon Jaeger]

Hi,

 

I'm trying to detect a properly formatted IP address from $_POST data. The IP also has a port in it. How would I detect a properly formatted IP address like this?

 

72.5.86.196:27015

 

The ports will vary, so it's not going to be 27015 every time.

 

Currently I'm doing it like so:

		if(!strlen($s_ip) || strpos($s_ip, ":") !== true || strpos($s_ip, ".") !== true)
	{
		$error = true;
		$error_msg .= "<li>The IP is not formatted correctly or you haven't entered one</li>";
	}

That method is very simple as you can tell. It doesn't work too well. It always executes whats inside of the curly brackets even when the IP is properly formatted.

 

Thanks.

Brandon

Nevermind. I figured out a solution.
