What are the potential pitfalls of creating dynamic table names in a database using PHP?

One potential pitfall of creating dynamic table names in a database using PHP is the risk of SQL injection attacks if user input is not properly sanitized. To mitigate this risk, always use prepared statements with parameterized queries to prevent malicious SQL code from being injected into the query. 

// Example of using prepared statements to create dynamic table names in a database

// Assuming $tableName is the dynamic table name provided by user input
$tableName = $_POST['table_name'];

// Establish a database connection
$pdo = new PDO("mysql:host=localhost;dbname=mydatabase", "username", "password");

// Prepare a statement with a parameterized query
$stmt = $pdo->prepare("SELECT * FROM $tableName WHERE id = :id");

// Assuming $id is another dynamic value provided by user input
$id = $_POST['id'];

// Bind the parameter to the statement
$stmt->bindParam(':id', $id);

// Execute the statement
$stmt->execute();

// Fetch the results
$results = $stmt->fetchAll();

// Do something with the results
foreach ($results as $row) {
    // Process each row
}
