So, you want to view the search results in another page? I understand that English is not your primary language but a little more explanation is needed.

ok i have this code java to excute select option value

<script type="text/javascript">
        $(document).ready(function() {
            $('#sortBy').change(function() {
                $.get('data.php', { sort: $(this).val() }, function(data) {
                    $('#response').html(data);
                });
            });
			// Trigger the change event when the page loads
    		$('#sortBy').trigger('change');
        }); 
        </script>

Select allOpen in new window

and other data.php file is

<?php 
error_reporting(E_ALL);
ini_set('display_errors', 1);

$dbh = new PDO("mysql:host=$localhost;dbname=$db_name", $db_users, $db_password);
$dbh->setAttribute(PDO::ATTR_DEFAULT_FETCH_MODE, PDO::FETCH_OBJ);

switch ($_GET['sort']):

    case "1":
        $sql = "SELECT * FROM packages ORDER BY Package_Price ASC";
        break;

    case "2":
        $sql = "SELECT * FROM packages ORDER BY Package_Price DESC";
        break;

    default:
        $sql = "SELECT * FROM packages ORDER BY Package_Price";

endswitch;

// Prepare the IMG query to be used later on
$imgQuery = $dbh->prepare("SELECT content FROM packages_image WHERE packageID = ? LIMIT 1");

// Execute the Packages query
$packages = $dbh->query($sql);

// Loop through the Package results
while ($package = $packages->fetch()): ?>

    <?php
    // Get the image data from the prepared query
    $imgQuery->execute(array($package->package_id));
    $imgData = $imgQuery->fetchColumn();
    ?>

        <div class="col-lg-6 portfolio-item">
            <div class="card h-100">
                <a href="ViewDetails.php?id=<?php echo $package->package_id ?>">
                  <?php  echo '<img src="data:image/jpeg;base64,'.base64_encode($imgData).'" width="100%" height="350px"/>'; ?>
                </a>
                <div class="card-body">
                    <h4 class="card-title">
                        <a href="ViewDetails.php?id=<?php echo $package->package_id ?>"><?php echo $package->package_name ?></a>
                    </h4>
                  <h3 class="breadcrumb" style="color:#C00; text-align:center"><?php echo $package->Package_Price ?> euro.</h3>
                    <p class="card-text"><?php echo substr($package->Detailed_Itinerary, 0, 150) ?></p>

i have div with inputs and submit button to make another search how can i do ??

Still not clear enough. We need explanation of what you want, not just code.

i have div with inputs and submit button above this select element  to make another search how can i do without conflict results??

In none of your code do I see an element with the id response or the id sortBy
If you want us to fully understand what you need, one line answers that really do not show us isn't going to help.

<div class="float-left">Packages Found : <span style="color:red"><?php echo $resultcount['COUNT(package_name)']; ?></span></div>
                    <div class="float-right" style="display:inline">
                        <style>
                        #duration{width:200px;}
                        </style>
                                    
                        <select id="sortBy" class="form-control" style="width:250px;">
                            <option value="2">Star Rating (1-5)</option>
                            <option value="1">Star Rating (5-1)</option>
                        </select>

       
                    </div>
                  </div>
        </div>
            <br>

      <div class="container">

       <!-- Page Heading/Breadcrumbs -->

        <div class="row" id="response"></div>
