What data type for storing EUI-64 address in (postgresql) database -


what datatype storing eui-64 address (for zigbee nodes)?

eui-64 address 8 octets. can gather should not considered integer such, though can make 64 bit integer out of them. seems obvious use bigint, though "signed" unfortunately makes bit messy.

i use numeric(8), there no built in conversions represent hex (though write one).

i use char(16), seems wasteful.

all of these options usable each seems bit messy. i'm wondering if has thoughts on or way haven't thought of. using bigint, working fine far. allows me use "to_hex" represent address, can foresee problems unless handle sign-ness properly.

thanks.

i write own data type it, using code macaddr template.

php - Accessing static methods using newly created $obj or using class Name -

see class definition below: i using 5.3.9 version of php class a{ static function ab(){ echo "static function ab<br>"; } public function xy(){ echo "public function xy<br>"; } } $obj = new a(); $obj->ab(); a::ab(); both functions call give same output without error static function ab static function ab how possible static method can called class object? because static method calls using class name only?! now difference between accessing these 2 ways call static method ? referring php.net website declaring class properties or methods static makes them accessible without needing instantiation of class. property declared static can not accessed instantiated class object (though static method can). a big difference is because static methods callable without instance of object created, pseudo-variable $this not available inside method declared static. refer page php.net/manual/en/
