I’m new to php . Please help me with this problem.

<?php  include 'config.php';

$output = ' ';
if (isset($_POST['query'])) {
  $search= $_POST['query'];
  $stmt=$conn->prepare("SELECT * FROM live_search WHERE first_name LIKE CONCAT('%'.?.'%') OR last_name LIKE CONCAT('%'.?.'%')");
else {
  $stmt = $conn->prepare("SELECT * FROM live_search");
$result = $stmt->get_result();

if ($result->num_rows>0) {
    <th>first name</th>
    <th>last name</th>
  while ($row=$result->fetch_assoc()) {
    $output .= " <tr>
      <td> ". $row['id'] ." </td>
      <td> ". $row['first_name'] ." </td>
      <td> ". $row['last_name'] ." </td>
      <td> ". $row['email'] ." </td>
      <td> ". $row['gender'] ." </td>
    </tr> ";
  $output .= "</tbody>";
  echo $output;


Hello and welcome to the forum :grin:!

As stated on the documentation of PHP:

Which means your expected statement object is instead a boolean. You should check what the error says:

if (false === $stmt) {
  // Log the error and handle it:
  error_log('Could not create a statement:' . $conn->error);

Though the documentation references the procedural call, it applies to the OOP style too.
