This may not be the most elegant solution. Let's call your array
$origArray
$tmpArray = array();
foreach( $origArray as $elKey => $elArray ) {
$tmpArray[$elArray['quantity']] = $elKey;
}
if( ksort( $tmpArray )) {
$sortedArray = array();
foreach( $tmpArray as $elKey ) {
$sortedArray[$elKey] = $origArray[$elKey];
}
echo 'Original: <pre>' . print_r( $origArray, TRUE ) '</pre><br>';
echo 'Sorted: <pre>' . print_r( $sortedArray, TRUE ) '</pre>';
} else {
echo 'Sorry, couldn\'t sort';
}
thnx,
Chris
