What potential pitfalls should be considered when implementing a page generation system in PHP for database entries?

One potential pitfall to consider when implementing a page generation system in PHP for database entries is the risk of SQL injection attacks if user input is not properly sanitized. To prevent this, always use prepared statements or parameterized queries when interacting with the database to avoid malicious code execution. 

// Example of using prepared statements to query the database
$pdo = new PDO('mysql:host=localhost;dbname=database', 'username', 'password');

$stmt = $pdo->prepare("SELECT * FROM table WHERE id = :id");
$stmt->bindParam(':id', $id, PDO::PARAM_INT);
$stmt->execute();

while ($row = $stmt->fetch()) {
    // Process the database results
}
