How can PHP developers efficiently manage data mutations, such as adding new records and deleting existing ones in a database table?

To efficiently manage data mutations in a database table, PHP developers can use SQL queries to add new records or delete existing ones. By using prepared statements and parameterized queries, developers can prevent SQL injection attacks and ensure data integrity. Additionally, using transactions can help maintain the consistency of the database when performing multiple mutations. 

// Adding a new record to a database table
$pdo = new PDO("mysql:host=localhost;dbname=mydatabase", "username", "password");
$stmt = $pdo->prepare("INSERT INTO table_name (column1, column2) VALUES (:value1, :value2)");
$stmt->bindParam(':value1', $value1);
$stmt->bindParam(':value2', $value2);
$value1 = 'new_value1';
$value2 = 'new_value2';
$stmt->execute();

// Deleting an existing record from a database table
$pdo = new PDO("mysql:host=localhost;dbname=mydatabase", "username", "password");
$stmt = $pdo->prepare("DELETE FROM table_name WHERE id = :id");
$stmt->bindParam(':id', $id);
$id = 1;
$stmt->execute();
