See the example in the PHP manual to know how to print out unsigned integer.

[2010-05-26 12:45 UTC] olafvdspek at gmail dot com

I know how to print an uint, that's not my question!

[2010-05-26 13:10 UTC] pajoye@php.net

So what are you asking then? That's exactly what you are experiencing. There is no bug.

[2010-05-26 13:11 UTC] olafvdspek at gmail dot com

I'm asking for ip2long to return the same (negative) values on all platforms.

[2010-05-26 15:06 UTC] pajoye@php.net

So no, you don't know what an unsigned integer value is. Please ask support in one of the numerous php support channels.

[2010-05-26 15:25 UTC] olafvdspek at gmail dot com

I know perfectly well what an unsigned int is.

[2010-05-26 17:13 UTC] salathe@php.net

So what are you requesting? That ip2long returns a string representation of the 
number, or a float? Of which value 3221234342 or -107373295?

[2010-05-26 17:16 UTC] olafvdspek at gmail dot com

Returning -107373295 on x64 would make it consistent with x86.

But people might prefer 3221234342, in which case it could be returned as a string.

[2010-05-26 23:26 UTC] johannes@php.net

This would be a different binary representation, which breaks binary math, which people often do with IP addresses.

[2010-05-26 23:28 UTC] olafvdspek at gmail dot com

Then just return the negative value.

[2010-05-27 08:25 UTC] mike@php.net

Please read up on that topic and stop complaining about nothing.
You may start here or anywhere else:

Like I said before, I know what signed and unsigned shorts, ints, longs and long longs are.

This is why I peruse bugs.php.net... for the lulz when somebody submits a bogus bug and makes themself look stupid.
