What are the implications of manually overriding the PDOStatement class for query logging in PHP applications?

When manually overriding the PDOStatement class for query logging in PHP applications, it is important to ensure that the overridden methods correctly log the queries without affecting the functionality of the PDOStatement class. This can be achieved by extending the PDOStatement class and implementing custom logging logic in the execute() and fetch() methods. 

class CustomPDOStatement extends PDOStatement {
    protected function __construct() {}

    public function execute($input_parameters = null) {
        // Log the query before executing
        $query = $this->queryString;
        // Implement custom logging logic here
        // Execute the query
        return parent::execute($input_parameters);
    }

    public function fetch($fetch_style = null, $cursor_orientation = PDO::FETCH_ORI_NEXT, $cursor_offset = 0) {
        // Log the fetch operation
        // Implement custom logging logic here
        // Fetch the result
        return parent::fetch($fetch_style, $cursor_orientation, $cursor_offset);
    }
}

// Set the custom PDOStatement class for logging queries
$pdo = new PDO('mysql:host=localhost;dbname=test', 'username', 'password');
$pdo->setAttribute(PDO::ATTR_STATEMENT_CLASS, ['CustomPDOStatement']);
