Its worth noting to delete from an array you must use the array directly example unset( $a[400] ) you cannot place that element into a variable then expect to unset it and remove it from the array it will not instead it will simple set the element int the array to zero.

Example

unset( $a ); // Delete single variable named
unset( $a[500] ); // Delete variable from array
unset( $a["test"] ); // Delete variable from hash
