Are there any potential pitfalls to be aware of when using MySQL delete commands in PHP?

One potential pitfall when using MySQL delete commands in PHP is the risk of accidentally deleting more data than intended if the query is not properly constructed. To avoid this, always double-check the conditions in the DELETE query to ensure only the desired records are being deleted. 

// Example of a safe DELETE query in PHP using MySQLi
$mysqli = new mysqli("localhost", "username", "password", "database");

// Check connection
if ($mysqli->connect_error) {
    die("Connection failed: " . $mysqli->connect_error);
}

// Define the DELETE query with proper conditions
$id = 1;
$sql = "DELETE FROM table_name WHERE id = ?";

// Prepare the statement
$stmt = $mysqli->prepare($sql);
$stmt->bind_param("i", $id);

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

// Close the statement and connection
$stmt->close();
$mysqli->close();
