PHP

Format : $salesData[“suppliers”][$supplierkey][‘sales’][$salesPeriod][‘sales’]

I want to sort (desc):

the key $salesData[“suppliers”][$supplierkey] by the numerical value populated in $salesData[“suppliers”][$supplierkey][‘sales’][0][‘cost’]

So in this example:

$salesData[“suppliers”][Dong]
$salesData[“suppliers”][Ding]

Would change to be:

$salesData[“suppliers”][Ding]
$salesData[“suppliers”][Dong]

Because

$salesData[“suppliers”][Ding][sales][0][cost] = 231.0600
$salesData[“suppliers”][Dong][sales][0][cost] = 92.8900

Is it possible to do it on multidimension arrays

I assume I need to use array_multisort some how?

Any advise would be appreciated
