Re: Sort Array by date

an easy way, but might not work in your case is to use sort() if instead of storing the dates like 12-04-2003, could you prehaps store them as 2003-04-03 year-month-day and then you could use $datearray = sort($datearray, SORT_STRING); would this work for you? -- Luke "Matt Palermo" <webmaster@sweetphp.com> wrote in message news:20031204221535.55971.qmail@pb1.pair.com... > I have a bunch of dates in the form: MM-DD-YYYY in an array and I want to > sort them and display them in descending order.
