$s = (($salary['check_amt'] / $emp_tot_month_days) * $tot_pre_days);
$esi_amt = (($s * $esi_percentage_value) / 100);
$esideduct = round($esi_amt);
$esidedon = round($emp_total_present_days_salary);
$s = (($salary['check_amt'] / $emp_tot_month_days) * $tot_pre_days);
$esi_amt = (($s * $esi_percentage_value) / 100);
$esideduct = round($esi_amt);
$esidedon = round($emp_total_present_days_salary);
$percentage_value = get_app_config('p_f');
$emppf = $pf_deducted_on * $percentage_value;
$pt_first_basic_amount_value = get_app_config('pt_first_basic_amount');
$pt_first_basic_limit_value = get_app_config('pt_first_basic_limit');
$pt_final_amount_value = get_app_config('pt_final_amount');
