How can the process of inserting data into relational tables be optimized in PHP?

When inserting data into relational tables in PHP, one way to optimize the process is to use prepared statements. Prepared statements help prevent SQL injection attacks and can also improve performance by allowing the database to reuse the query plan. By using prepared statements, you can separate the SQL query from the data values, which can be especially beneficial when inserting multiple rows of data at once.

// Establish a database connection
$pdo = new PDO("mysql:host=localhost;dbname=mydatabase", "username", "password");

// Prepare a SQL statement with placeholders
$stmt = $pdo->prepare("INSERT INTO my_table (column1, column2) VALUES (:value1, :value2)");

// Bind the values to the placeholders
$value1 = "some value";
$value2 = "another value";
$stmt->bindParam(':value1', $value1);
$stmt->bindParam(':value2', $value2);

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