How does the parsed query look like, is everything correct?

The parsed query should accurately represent the user's input and be structured in a way that can be easily executed by the database. To ensure everything is correct, check that the query syntax is valid, all necessary parameters are included, and any user input is properly sanitized to prevent SQL injection attacks.

// Example of a properly structured parsed query
$query = "SELECT * FROM users WHERE username = :username";
$stmt = $pdo->prepare($query);
$stmt->bindParam(':username', $username, PDO::PARAM_STR);
$stmt->execute();
