How can the use of mysqli improve the efficiency and security of database queries in PHP, as suggested by a forum member?

Using mysqli improves the efficiency and security of database queries in PHP by offering prepared statements, which help prevent SQL injection attacks. Prepared statements allow for parameterized queries, separating SQL logic from user input, reducing the risk of malicious code execution. Additionally, mysqli provides improved error handling and support for transactions, enhancing the overall robustness of database interactions. 

// Connect to the database using mysqli
$mysqli = new mysqli("localhost", "username", "password", "database");

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

// Prepare a statement to insert data into a table
$stmt = $mysqli->prepare("INSERT INTO table_name (column1, column2) VALUES (?, ?)");

// Bind parameters and execute the statement
$stmt->bind_param("ss", $value1, $value2);
$value1 = "Value 1";
$value2 = "Value 2";
$stmt->execute();

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