/** dateDiff() function
* returns Array of Int values for difference between two dates
* $date1 > $date2 --> positive integers are returned
* $date1 < $date2 --> negative integers are returned
*
* $split recognizes the following:
* 'yw' = splits up years, weeks and days (default)
* 'y' = splits up years and days
* 'w' = splits up weeks and days
* 'd' = total days
*
* examples:
* $dif1 = dateDiff() or dateDiff('yw')
* $dif2 = dateDiff('y')
* $dif3 = dateDiff('w')
* $dif4 = dateDiff('d')
*
* assuming dateDiff returned 853 days, the above
* examples would have a print_r output of:
* $dif1 == Array( [y] => 2 [w] => 17 [d] => 4 )
* $dif2 == Array( [y] => 2 [d] => 123 )
* $dif3 == Array( [w] => 121 [d] => 6 )
* $dif4 == Array( [d] => 847 )
*
* note: [h] (hours), [m] (minutes), [s] (seconds) are always returned as elements of the Array
