What are some potential pitfalls to be aware of when dynamically generating date ranges in PHP queries?

One potential pitfall when dynamically generating date ranges in PHP queries is not properly sanitizing user input, which can lead to SQL injection attacks. To mitigate this risk, always use prepared statements with bound parameters to safely handle user input in SQL queries. 

// Example of dynamically generating a date range in a SQL query using prepared statements
$start_date = $_POST['start_date'];
$end_date = $_POST['end_date'];

// Prepare the SQL query with placeholders for the date range
$stmt = $pdo->prepare("SELECT * FROM table WHERE date BETWEEN :start_date AND :end_date");

// Bind the parameters to the placeholders
$stmt->bindParam(':start_date', $start_date);
$stmt->bindParam(':end_date', $end_date);

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

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