If they want the key(s) then min() won't work. And regarding algorithm speed: http://dev.3ft9.com/php/min-date.php The difference between sorting and foreach is minimal, so it probably doesn't matter which is used as far as performance goes. In my experience, unless you're dealing with Google-sized usage or high-throughput pipelines this sort of optimisation is a waste of developer time, especially when you compare this time difference to the time PHP will spend waiting for databases to do their thing. -Stuart -- Stuart Dallas 3ft9 Ltd http://3ft9.com/ > On Mon, 4 May 2015 10:45 am Shawn McKenzie <shawn@xxxxxxxxxxxxx> wrote: > > > How about min()?
