What are some best practices for securely deleting data from a database using PHP?

When deleting data from a database using PHP, it is important to securely delete the data to prevent any potential security risks. One best practice is to use prepared statements with parameterized queries to prevent SQL injection attacks. Additionally, before deleting the data, it is recommended to validate the user's input and ensure they have the necessary permissions to delete the data. 

// Connect to the database
$pdo = new PDO('mysql:host=localhost;dbname=mydatabase', 'username', 'password');

// Prepare a SQL statement with a parameterized query
$stmt = $pdo->prepare("DELETE FROM mytable WHERE id = :id");

// Bind the parameter and execute the query
$stmt->bindParam(':id', $id, PDO::PARAM_INT);
$stmt->execute();
