However, the array output is not complete.

 print_r($all_date); Array ( [1] => 2013-06-06 )

 $all_date = array(); $s = 1;

It is required to declare these variables BEFORE the beginning of the declaration of for loops.

    I didn't understand anything either, but maybe it should be

     for($f=0;$f<count($stud_array);$f++)

    etc. :)
