how do i test if a property of a stdclass object is set, even if its
value is null, similar to how array_key_exists() works for arrays.
the following method fails:
$a->b = null;
if(isset($a->b))
echo "yes";
and property_exists() seems only to work for defined objects.
hope someone can h
the solution has been found. array_key_exists() can actually be used
on objects, and yields the correct result.

thanks to dordea cosmin for pointing this out.

the source of the problem is gethostbyaddr(). it seems to have a 4,5
second timeout, so some lookups time out after 4,5 seconds, while most
of them are resolved in < 0.1 second; a radically performance
difference.

yeah but i assume this assumes you are on a unix machine and have
administrator rights. it would be nice to be able to look up ip
addresses swiftly and automatically on any machine and any operating
system running php.

thanks, but that won't work. i need to see post data from other people
out there, not my own data. still a mystery to me why php doesn't let

hello
does php have any built-in functions to convert post data from
whatever format it arrives in to whatever format i wish?
example:
i use iso-8859-1 internally, and even specify
accept-charset=iso-8859-1 in my html, but some browsers (phones) send
utf-8 anyway.
do i have to manually check if
i specify iso-8859-1 in both header and body:
if two different people post the norwegian phrase "Godt nytt år"

yep, a for loop is the fallback i use now.
any reason why there isn't a built-in function for this?
any plans for it in future versions of php?
