Answer 1

Put your code inside a function and just call that function after include statement.
//information_function//
<?php
include "../connection/connection.php";
function get_information(){
$sql = "SELECT * FROM registration";
$result = mysqli_query($dbconn, $sql);
while ($row = mysqli_fetch_array ($result)){
echo "<tr>";
echo "<td>" . $row['lname'] . "</td>";
echo "<td>" . $row['address'] . "</td>";
echo "<td>" . $row['contact'] . "</td>";
echo "</tr>";
}
}
?>
//html//
<div class="member_list">
<div class="list-unstyled">
<?php require_once "../function/admin_function.php"; ?>
</div>
</div>
<div class="information" id="table_information">
<table class="table_information">
<tr>
<th colspan="4">Information</th>
</tr>
<tr>
<th>lastname</th>
<th>address</th>
<th>contact</th>
</tr>
<?php include "../function/information_function.php"; ?>
<?php get_information(); ?>
</table>
</div>
