convert IP to 10 digit decimal number

Hi guys I need help in converting IP in php.

for example, if we have this IP: 123.456.789.012

I would like to make it as 012.789.456.123

and then convert it to a 10 digit decimal number. This is for a hack I am working on and will be greatful if anyone can help.

Thanks

Aurous

Why 10 digits, why not 12?

ya I understood the ip2long function. How about reversing the IP address before I use the function?

How about:

PHP Code:


		
			
$reversedlong = ip2long(implode(".",array_reverse(explode(".", $ip))));

That's what I was going to suggest as well.

Actually the way I need to reverse is as follows:

If the IP is suppose: 123.456.78.90

It should reverse it to 90.78.456.123

They way you suggest would make it 321.654.87.09 (i think), which I dont want to do.

basically if the IP I need to get this -> 3092948441 when this is entered as IP -> 217.165.90.184

This is an example.

Don't think too much ;)

It would already do that, i a review with the ip you now provided i found out that the sprintf is really neccesary to avoid negative numbers.

PHP Code:


		
			
<?php

$ip = "217.165.90.184";

echo "<br />ip: $ip";

$reversed = implode(".",array_reverse(explode(".", $ip)));

echo "<br />reversed: $reversed";

$reversedlong = sprintf("%u",ip2long(implode(".",array_reverse(explode(".", $ip)))));

echo "<br />reversedlong: $reversedlong";

?>

Will produce:

Code:

ip: 217.165.90.184

reversed: 184.90.165.217

reversedlong: 3092948441
