ip2long

(PHP 4 >= 4.0.0)

ip2long --  Converts a string containing an (IPv4) Internet Protocol dotted address into a proper address.

Description

int ip2long ( string ip_address)

The function ip2long() generates an IPv4 Internet network address from its Internet standard format (dotted string) representation.

Note: Because PHP's integer type is signed, and many IP addresses will result in negative integers, you need to use the "%u" formatter of sprintf() or printf() to get the string representation of the unsigned IP address.

This second example shows how to print a converted address with the printf() function :
