Are there any security considerations to keep in mind when retrieving the last inserted ID value in PHP?

When retrieving the last inserted ID value in PHP, it is important to ensure that the operation is secure to prevent any potential security vulnerabilities. One common security consideration is to avoid directly embedding user input into the SQL query used to retrieve the last inserted ID, as this can lead to SQL injection attacks. Instead, it is recommended to use prepared statements with parameterized queries to safely retrieve the last inserted ID value. 

// Securely retrieve the last inserted ID value using prepared statements
$stmt = $pdo->prepare("SELECT LAST_INSERT_ID()");
$stmt->execute();
$lastInsertedID = $stmt->fetchColumn();
