What are the benefits of using INSERT INTO queries with multiple value sets compared to executing individual queries in a nested loop structure in PHP?

Using INSERT INTO queries with multiple value sets is more efficient than executing individual queries in a nested loop structure in PHP because it reduces the number of database transactions, resulting in faster execution and improved performance. This approach also helps in minimizing the overhead of establishing multiple connections to the database server.

// Example of using INSERT INTO queries with multiple value sets

// Sample data to insert
$data = [
    ['John', 'Doe'],
    ['Jane', 'Smith'],
    ['Alice', 'Johnson']
];

// Construct the query
$query = "INSERT INTO users (first_name, last_name) VALUES ";

// Loop through the data and build the query
foreach ($data as $row) {
    $query .= "('" . $row[0] . "', '" . $row[1] . "'), ";
}

// Remove the trailing comma and execute the query
$query = rtrim($query, ', ');
$result = mysqli_query($connection, $query);

if ($result) {
    echo "Data inserted successfully.";
} else {
    echo "Error inserting data: " . mysqli_error($connection);
}
