<form method="post" action="export.php">
<input type="submit" name="export" class="btn btn-success" value="Export" />
</form
**export.php**
<?php
$connect = mysqli_connect("localhost", "root", "", "testing");
$output = '';
if(isset($_POST["export"]))
{
$query = "SELECT * FROM tbl_customer";
$result = mysqli_query($connect, $query);
if(mysqli_num_rows($result) > 0)
{
$output .= '
<table class="table" bordered="1">
