This is a terribly inneficient way of handling your situation but I believe
it would work.
// First we're going to make a list of all company values
for($i=0; $i<count($myarray); $i++)
{
$company_values[] = $myarray[$i][company];
}
// Then we're going to order the array using a standard function.
natsort($company_values);
// Then we're going to go through $myarray looking for each matching
// value and build a new array based on the order of the sorted list.
for($i=0; $i<count($company_values); $i++)
{
for ($j=0; $j=<count($myarray); $j++)
{
if ($company_values[$i] == $myarray[$j][company])
{
$mynewarray[] = $myarray[$j];
}
}
}
// bada bing bada boom you gots your company sorted list... I think
$myarray = $mynewarray;
I wrote this off the top of my head in like three minutes so any and all
corrections would be most welcome. ;)
