I want to make search page where I want to display

I want to make search page(php) where I want to display my searched data from database in a "div"?I made a connection with database and searched for data in one phppage and created a div tag in another phppage.how can i display the searched data of one php page to be displayed in another php page's "div"

Search.php:

<?php 
include 'Searchdata.php';
include 'connect.php';
if(isset($_POST['submit'])){
   $searchkey= $_POST['search'];    
   $searchkey=preg_replace("#[^0-9a-z]#i", "", $searchkey); 
   $query = mysqli_query($conn, "SELECT * FROM newentry WHERE Date LIKE '%$searchkey%'")or die("Could not search!");
   $count = mysqli_num_rows($query); 
   if(!($count == 0)) {    
      while($row=mysqli_fetch_array($query)){
         $Date=$row['Date'];
         $Entry=$row['Entry'];
         echo'<div>'.$Date.'<br>'.$Entry.'</div>';
       }
    } else {echo "There was no search result!";} 
}?>

Searchdata.php:

<div>
<form action="Search.php" method="post">  
   <input type="text" name="search" placeholder="Search"> 
   <input type="submit" value="Search" />
</form>

Just create a variable to store the results in this case its $data. Move your include searchdata.php to the bottom of the code so it can reconize $data. Then echo it on your html page.

html page

<div>
<form action="Searchdata.php" method="post">  
<input type="text" name="search" placeholder="Search"> 
<input type="submit" value="Search">
</form>
<div><?php echo $data ?></div>
</div>

The PHP code.

<?php
include 'connect.php';
$data = '';
if(isset($_POST['submit'])){
$searchkey= $_POST['search'];   
$searchkey=preg_replace("#[^0-9a-z]#i", "", $searchkey); 
$query = mysqli_query($conn, "SELECT * FROM newentry WHERE Date LIKE '%$searchkey%'")or die("Could not search!");
$count = mysqli_num_rows($query); 
if(!($count == 0)) {    
while($row=mysqli_fetch_array($query)){ 
$Date=$row['Date'];
$Entry=$row['Entry'];
$data = '<div>'.$Date.'<br>'.$Entry.'</div>';
}
} else {
$data = "There was no search result!";}}
include 'Search.php';
?>
