How to get 32-bits IP address in php?

I think REMOTE_ADDR return a string, right?

Can I get the 4-bytes IP address?

Thanks!

 

First we find the four bytes of the address then, by shifting them to the left, we add to obtain the decimal IP address:

<?
	$bytes = explode(".", $_SERVER["REMOTE_ADDR"]);
	$decimal = ($bytes[0] << 24) + ($bytes[1] << 16) + ($bytes[2] << 8) + $bytes[3];
?>

PHP:

 

Damn, I just realised there's a built-in function for that ip2long:

int ip2long ( string ip_address )

Code (markup):

 

also if needed there is back to ip2long function - string long2ip ( int proper_address)
