Function hours_sum ($ hours_min ){

If (! Is_array ($ hours_min) return false;

$ Tmp_arr = array ();
Foreach ($ hours_min as $ v ){
$ Tmp_arr = explode (':', $ v );
$ Hour [] = $ tmp_arr [0];
$ Min [] = $ tmp_arr [1];
}

$ Hours = array_sum ($ hour );
$ Mins = array_sum ($ min );

$ Mins = $ mins> = 10? Str_pad ($ mins, 2, 0, STR_PAD_RIGHT): $ mins;

$ Min = $ sec % 60;
