Bug Type: Unknown/Other Function
Operating System: FreeBSD 4.4-STABLE i386
PHP Version: 4.1.2
New Comment:
I've done a little more digging to see why the problem occured. I'm
not 100% sure if it is a problem with php, or misuse of php really.
However it might be worth adding in something to make this work.
My script was getting the decimal address as a string, an integer. The
following example should illustrate it.
<?
$moo = "167772161";
echo long2ip($moo);
echo "<BR>";
$moo = 167772161;
echo long2ip($moo);
?>
As a side thing you also need to add the following to get larger
numbers to work when using strings:
if ($moo > 0) $moo += pow(2,32);

Sorry, I missed out a bit:
inet4oct blah;
;)

Can you provide a simple sample script with data that shows the
problem?

I have found some problems where long2ip (and I would presume ip2long
by the same token) seems to return an IP address offset by one. I'm
not sure if it is the implmentation of inet_ntoa on the platform I am
using or something else.
Even if this is a problem with a particular version of a library on my
machine, maybe it might be worth using a method other than inet_ntoa
for ease of platform independance?
Perhaps something along there lines.... ?
struct inet4addr {
unsigned int a:8;
unsigned int b:8;
unsigned int c:8;
unsigned int d:8;
};
typedef union {
unsigned int inet4dec;
struct inet4addr inet4oct;
} inet4oct;
blah.inet4dec = <SOME LONG IP HERE>;
printf("%i.%i.%i.%i\n", blah.inet4oct.a,
blah.inet4oct.b,blah.inet4oct.c,blah.inet4oct.d);
