What are some common pitfalls in PHP when dealing with database operations like deleting entries?

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

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

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

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

// Set the id to delete
$id = 1;

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