I want to sort the array by the array by the value in field_device_category. Basically, I want to group the results but first I need to make sure all the objects are sorted by field_device_category.
Thanks in advance!
Use usort for this kind of sorting. It uses Quicksort in the background and takes a user-defined function to compare the array elements:
usort($array, "complicatedArrayComparer");
function complicatedArrayComparer($a,$b)
{
if ($a['field_device_category'] == $b['field_device_category']) {
return 0;
}
return ($a['field_device_category'] < $b['field_device_category']) ? -1 : 1;
}
