使用PDO搜索数据库[重复]

This question already has an answer here:

I am attempting to create a search function for my website using PDO. At the moment I send the search query through the URL and then try to fetch the results however whenever I do a var dump it returns null. I tested the query on PHP my admin and it returns around 4 results.

I use a class I created to connect to the database, this works on all my other queries.

Here is my search function

function search($query) {

    $sql = "SELECT * FROM `Sweets` WHERE `Description` LIKE :search";
    $stmt = $this->connection->prepare($sql);
    $stmt->bindParam(':search', $query);

    $stmt->execute();

    $done = $stmt->fetch();

    var_dump($done[0]);


}

Below is the search php my form calls as an action

<?php
// Start our connecting to our database
require('class-database-functions.php');

$database = new Database_Functions();

// Get the search value passed through $_GET
$search_query = $_GET['query'];

$search = $database->search($search_query);


?>
</div>

    Try this

    $sql = "SELECT * FROM `Sweets` WHERE `Description` LIKE ?";
    $stmt = $this->connection->prepare($sql);
    $stmt->bindValue(1, "%$query%",PDO::PARAM_STR);
