md5(uniqid("", true))
is the better method. time()
and mktime()
are accurate to one second, so two executions within the same clock second would produce duplicate keys.
php mktime() or uniqid()

Question
I am using one of these to create a serial key. I would like to know md5(uniqid()) or md5(mktime()) better to be use?
Which one has a less change to get a duplicated key?
