unix time and microtime

toshog

hi all..

is there anyway to use mktime() to make up time down to milliseconds?

to be able to compare times (in the future) that are very close to each other.
to get those times i use microtime() and concatenate the seconds with the milliseconds stripping the 0s (zeros). assuming here that it's impossible to have two different processes that will return the same microtime. ever...

(one way to solve this is to add 6 digit random numbers after the time that mktime comes up with... i guess...)

also - on a different note - is there a better way to create consecutive numbers in php (without using a stored value in a db) than using the unix microtime?!

thanks....

Creating consecutive numbers... you mean like a [man]range/man ?

As for your wanting milliseconds to use with mktime, I don't think it's really possible to do what you want.

range is not working. i need to be able to create a increasing (hopefully system) number without using a database. in other words if i have a few processes/calls to the same application i need to be able to consecutively number those. if i use database to store those it's not really fast enough sometimes. and two of the same processes get the same number out of the database and update it. it's just not fast enough. so the unix time is a logical solution. with one big problem. it's too long of a string concatenated.

so i was wondering if there is another way to do that....

You need to lock the db table while incrementing the counter.
The other process will have to wait for the lock to be released.

You could do the same with a simple file containing the sequential number, but still file locking would be required, it would be a lot quicker than a db.
