How to sum total value of any foreach loop result - php

Question

I want to show Total Salary, which is the sum of all employee's net salary. How can I do that? I have tried some code but its not working
<tbody>
<?php
$salary = 0;
if (!empty($emp_salary_info)):foreach ($emp_salary_info as $v_emp_salary):
$salary = $salary + $v_emp_salary->basic_salary;
?>
<tr>
<td><?php echo $v_emp_salary->employment_id; ?></td>
<td><?php echo $v_emp_salary->first_name . ' ' . $v_emp_salary->last_name ?></td>
<td><?php echo $gross = $v_emp_salary->basic_salary + $v_emp_salary->house_rent_allowance + $v_emp_salary->medical_allowance + $v_emp_salary->special_allowance + $v_emp_salary->fuel_allowance + $v_emp_salary->phone_bill_allowance + $v_emp_salary->other_allowance ?></td>
<td><?php echo $deduction = $v_emp_salary->tax_deduction + $v_emp_salary->provident_fund + $v_emp_salary->other_deduction ?></td>
<?php $net_salary = $gross - $deduction ?>
<td><?php echo $net_salary ?></td>
<td><?php
if ($v_emp_salary->employment_type == 1) {
echo 'Provision';
} else {
echo 'Permanent';
}
?></td>
<td><?php echo btn_view('admin/payroll/view_salary_details/' . $v_emp_salary->employee_id); ?></td>
<td>
<?php echo btn_edit('admin/payroll/manage_salary_details/' . $v_emp_salary->employee_id . '/' . $v_emp_salary->designations_id); ?>
</td>
</tr>
<?php endforeach; ?>
<?php endif; ?>
</tbody>

?>
<?php echo $salary; ?>

I think you are using data-tables for displaying table records. Try to print Total after completing record calculations.
In image you are displaying total before completing process.
Also change few lines of code
if(!isset($v_emp_salary->basic_salary) || empty($v_emp_salary->basic_salary) || !is_numeric($v_emp_salary->basic_salary))
{
$v_emp_salary->basic_salary = 0;
}
$salary = $salary + $v_emp_salary->basic_salary;
Still if you do not find total try to check data inside $emp_salary_info it may have empty or wrong data with salary.
