我的php代码在localhost上运行得非常好，它提供了精确的输出。当我试图使它在线，搜索过滤器将无法工作，它给出的输出没有过滤器。

<?php

if(isset($_POST['search']))
{
    $valueToSearch = $_POST['valueToSearch'];

    $query = "SELECT * FROM product WHERE Name LIKE '%".$valueToSearch."%'";
    $search_result = filterTable($query);

}
 else {
    $query = "SELECT * FROM product";
    $search_result = filterTable($query);
}

// function to connect and execute the query
function filterTable($query)
{
    $connect = mysqli_connect("localhost", "root", "", "mall");
    $filter_Result = mysqli_query($connect, $query);
    return $filter_Result;
}

?>
