What common mistakes are made when using PHP to delete database records?

One common mistake when using PHP to delete database records 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 and execute the statement
$stmt->bindParam(':id', $_POST['id']);
$stmt->execute();
