Thanks, Tim -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Scott Trudeau Sent: Monday, May 07, 2007 11:49 AM To: NYPHP Talk Subject: Re: [nyphp-talk] How to sort a multi-dimensional array by a given key? I'm sure there's probably a better way to do this, but uasort() sorts an array using a callback provided callback function for item comparisons -- which you can use to compare the specific key you want to sort by. It seems like there should be a more generic way to do this by providing the name of the key on which you want to sort. $franchises['SCID1'] = SCNYC $franchises['SCID1']['BusinessName'] = SuperCoups of NY City $franchises['SCID1']['DistanceFromCustomer'] = 20 $franchises['SCID2'] = SCBUFF $franchises['SCID2']['BusinessName'] = SuperCoups of Buffalo $franchises['SCID2']['DistanceFromCustomer'] = 10 uasort($franchises, "cmp_distance"); function cmp_distance($a, $b) { if($a['DistanceFromCustomer'] == $b['DistanceFromCustomer']) return 0; return ($a['DistanceFromCustomer'] < $b['DistanceFromCustomer']) ? -1 : 1; } On 5/7/07, Timothy Boyden <[EMAIL PROTECTED]> wrote: > > > Hi All, > > I have a multi-dimensional array such as: > > $franchises['SCID1'] = SCNYC > $franchises['SCID1']['BusinessName'] = SuperCoups of NY City > $franchises['SCID1']['DistanceFromCustomer'] = 20 > > $franchises['SCID2'] = SCBUFF > $franchises['SCID2']['BusinessName'] = SuperCoups of Buffalo > $franchises['SCID2']['DistanceFromCustomer'] = 10 > > How can I sort this array so the businesses are sorted by the > DistanceFromCustomer key? > > Thanks for the help in advance, > > Tim > > > --------------------------- > Timothy Boyden > > Network Administrator > > [EMAIL PROTECTED] > > > > SuperCoups(r) > > > > 350 Revolutionary Drive | E.
