Since I have no way of knowing exactly what type of data you have...
I think it might be 
while ($cur_balance < ($balance * $i / $slice_count)) {
  $cur_balance += $cur_balances->[++$select];
}

that is killing you. If the data is such that @$cur_balances can be exhausted, then the while loop will never end because $cur_balances->[++$select] will keep returning 0.
