我的問題是，當我輸入一個特定的國家名稱時，例如：法國，它將輸出數據庫中的所有數據，而不僅僅是法國。我不知道哪里出了問題，可能很簡單，但我什至不知道如何嘗試解決問題，所以我來這里尋求幫助if ($_SERVER['REQUEST_METHOD'] == 'POST') {    $country = $_POST['country'];    $_SESSION['country'] = $country;    $sqlQuery = "SELECT * FROM campsites WHERE country LIKE '%$country%'";    $result = $campDataSet->fetchAllCamps($sqlQuery);    //var_dump($result);    if (count($result) > 0) {        echo'<div class="table-responsive">                <table class="table">                    <thead id="table1Head">                    <tr><td>Name</td>                        <td>Address</td>                        <td>Postcode</td>                        <td>Country</td>                        <td>Latitude</td>                        <td>Longitude</td>                        <td>email</td>                        <td>Phone<td>                   </thead>                    <tbody>            </div>';        foreach ($result as $row) {            echo '<tr><td>' . $row->campsite_name . '</td> <td>' . $row->address . '</td> <td>' . $row->postcode . '</td> <td>' . $row->country. '</td> <td>' . $row->lattitude . '</td> <td>' . $row->longitude . '</td> <td>' . $row->email . '</td> <td>' . $row->phone_number .
