How can you optimize the code for checking and inserting data into a MySQL database in PHP to improve performance?

One way to optimize the code for checking and inserting data into a MySQL database in PHP is to use prepared statements to prevent SQL injection attacks and improve performance by reducing the overhead of repeatedly parsing and compiling the same query. Prepared statements also allow for the reuse of a single query template with different parameters, which can further enhance performance. 

// Establish a connection to the MySQL database
$connection = new mysqli("localhost", "username", "password", "database");

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

// Prepare a SQL statement with placeholders for data insertion
$statement = $connection->prepare("INSERT INTO table_name (column1, column2) VALUES (?, ?)");

// Bind parameters to the prepared statement
$statement->bind_param("ss", $value1, $value2);

// Set the values of the parameters
$value1 = "value1";
$value2 = "value2";

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

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