Description ArraySorter class can be used to sort multidimensional arrays. It takes multidimensional array or an array of objects and sorts it by the given value. The sorting entry name may include one more entry names, one per each dimension. The sorting order may be configured also to be ascending or descending. 2. Preparing ArraySorter to do a job First of all create the instance of ArraySorter. Secondly set the array to sort using ArraySorter method setArray($array2Sort); 3. Sorting In the class there is public method sort($field, $direction) which can be used to sort given array. - Sorting by given field $field param is a string desribing field position in array. Each dimension of array is separated by a dot "." Suppose we have such an array [0]['name'] = 'something'; [0]['vandor']['name'] = 'company'; [0]['vandor']['address']['street'] = 'abbay road'; [1]['name'] = 'something else'; [1]['vendor']['name'] = 'company'; [1]['vendor']['address']['street'] = 'abbay road'; - to sort by name set param $field to 'name' - to sort by vendor name set param $field to '' - to sort by vendor street set param $field to 'vendor.address.street' The same naming convention are used to sort array of objects or mixed structures where araay can contains objecs which contains array fields. - Define sort order To define sort order, there are two constants in ArraySorter ArraySorter::DIRECTION_ASC - defining ascending sorting direction ArraySorter::DIRECTION_DESC - defining descending sorting direction These contants can be used as a second parametr for sort method. 4.
