Is it advisable to use SQLite as a replacement for MySQL in a PHP forum, considering potential performance issues with multiple parallel accesses?

Using SQLite as a replacement for MySQL in a PHP forum may not be advisable due to potential performance issues with multiple parallel accesses. SQLite is better suited for smaller applications with low traffic, while MySQL is more robust and can handle higher levels of concurrency. To improve performance in a PHP forum with multiple parallel accesses, consider optimizing your MySQL database queries, implementing caching mechanisms, and utilizing connection pooling. 

// Example of optimizing MySQL query using PDO prepared statements
$pdo = new PDO('mysql:host=localhost;dbname=forum_db', 'username', 'password');
$stmt = $pdo->prepare('SELECT * FROM posts WHERE user_id = :user_id');
$stmt->bindParam(':user_id', $user_id, PDO::PARAM_INT);
$stmt->execute();
$results = $stmt->fetchAll(PDO::FETCH_ASSOC);
