What are common pitfalls when using PHP to delete records from a database?

One common pitfall when using PHP to delete records from a database is not properly sanitizing user input, which can lead to SQL injection attacks. To prevent this, always use prepared statements with parameterized queries to securely delete records from the database. 

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

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

// Bind the parameter id to the actual value
$stmt->bindParam(':id', $_POST['id']);

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