Wish I could answer that for you, Tim. I've always done it this way and
hadn't thought of uasort() before Scott and Dan mentioned it. Hopefully
they'll be able to comment on it, because I'm curious, too.

Scott's solution worked for me, but is there any performance/security

Subject: Re: [nyphp-talk] How to sort a multi-dimensional array by a
given key?
Hi Tim,
array_multisort() should do the trick. See the manual
(http://php.net/array_multisort) for some examples ("Example 256.
Sorting database results") much like what you're describing.
Essentially, you'll have to loop through the array to create another
array something like:
$sortDistance['SCID1']=>20
$sortDistance['SCID2']=>10
and then call:
array_multisort($franchises, $sortDistance);

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
