[ale] recommend a good PHP/MYSQL list?

[George Carless]

Hi Drew,

It's a little bit tricky - and your best bet would probably be to just 
re-sort in PHP, as you suggest (it's fairly simple to do, as it 
happens).  Alternatively, the latest version(s) of MySQL do support 
sub-selects, so you could use that.

If you want to sort in PHP, just grab the whole result set into an Array, 
and then use the array_multisort() function.

To grab everything into an array, you could use:

foreach ($result as $row) { $resultarray[$count++] = $row; }

Then, assuming that your first field is the key on which you want to sort:

$resultarray = array_multisort($resultarray,SORT_ASC);

I think that's about right.  Hope it helps.
