Are there any potential pitfalls to be aware of when deleting specific data from a database in PHP?

When deleting specific data from a database in PHP, one potential pitfall to be aware of is not properly sanitizing user input, which can lead to SQL injection attacks. To prevent this, it's important to use prepared statements with parameterized queries to safely pass user input to the database. 

// 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
$stmt->bindParam(':id', $_POST['id']);

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