我正在嘗試使用Slim PHP Framework開發一個 PHP 作曲家應用程序，并嘗試migrations.php像這樣對文件進行更改<?phpdeclare(strict_types=1);require __DIR__ . '/../../src/App/App.php';try {    $settings = $app->getContainer()->get('settings');    $hostname = $settings['db']['hostname'];    $username = $settings['db']['username'];    $password = $settings['db']['password'];    $database = $settings['db']['database'];    $pdo = new PDO("mysql:host=$hostname", $username, $password); //Possibly the connection    $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);    $sql = "DROP DATABASE IF EXISTS $database";    $pdo->exec($sql);    echo "[OK] Database droped successfully" . PHP_EOL;    $sql = "CREATE DATABASE $database";    $pdo->exec($sql);    echo "[OK] Database created successfully" . PHP_EOL;    $sql = "USE $database";    $pdo->exec($sql);    echo "[OK] Database selected successfully" . PHP_EOL;    $sql = file_get_contents(__DIR__ . '/../../database/database.sql');    $pdo->exec($sql);    echo "[OK] Tables created successfully" . PHP_EOL;//    echo "[OK] Records inserted successfully" . PHP_EOL;    $data = file_get_contents(__DIR__ . '/../../database/companies.json');    $array = json_decode($data, true);    foreach($array as $row) {        $relationships = $row["relationships"];        $pdo->exec($sql);    }    echo "[OK] Json inserted into tables successfully" . PHP_EOL;} catch (PDOException $e) {    echo "[ERROR] " . $e->getMessage() . PHP_EOL;}
