Dapatkan daftar tabel MySQL dan jalankan kode untuk setiap tabel

Gunakan SHOW TABLES :

$pdo = new PDO('mysql:dbname=mydb', 'myuser', 'mypass');
$stmt = $pdo->query('SHOW TABLES;');

if ($stmt->rowCount() > 0) {
    $tables = $stmt->fetchAll(PDO::FETCH_NUM);
    foreach ($tables as $table) {
        $table_name = $table[0];
        // do something
    }
}
