I believe this will cleanup your array: remove empty elements (those that evaluate to empty, eg "" and 0 equally), remove duplicate elements, and sort it.

$cleaned = array_map('array_filter', $array_to_be_cleaned);
$cleaned = array_map('array_unique', $cleaned);
$cleaned = array_map('sort', $cleaned);

To filter out the empty elements of the array, check out array_filter. To sort the elements, check out sort (or refer to this list of sorting functions to see what meets your needs)

$newarray = array_filter($myarray);
sort($newarray);

This will take the array you pass it (ie. $myarray) and it will strip out any empty values, then it will store the results to $newarray. After that, sort will organize the remaining values from least to greatest.

unset( $var['ufile']['type'] );
unset( $var['ufile']['tmp_name'] );

To sort, use sort(), usort(), or any other you want. Here's a good comparison of the different sort methods.

Try array_filter($array). It will remove all NULL elements and return the cleared array.
