In what scenarios would it be more efficient to use MySQL for generating combinations compared to PHP?

MySQL is more efficient for generating combinations when dealing with large datasets or when the combinations need to be stored in a database for future reference. This is because MySQL can handle complex queries and operations more efficiently than PHP. Additionally, using MySQL can reduce the load on the PHP server and improve overall performance. 

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

// Generate combinations and insert into MySQL table
$mysqli->query("CREATE TABLE combinations (id INT AUTO_INCREMENT PRIMARY KEY, combination VARCHAR(255))");

for ($i = 1; $i <= 10; $i++) {
    for ($j = 1; $j <= 10; $j++) {
        $combination = $i . "-" . $j;
        $mysqli->query("INSERT INTO combinations (combination) VALUES ('$combination')");
    }
}

// Retrieve combinations from MySQL table
$result = $mysqli->query("SELECT * FROM combinations");
while ($row = $result->fetch_assoc()) {
    echo $row['combination'] . "<br>";
}

// Close MySQL connection
$mysqli->close();
