What are the advantages of using a database over processing CSV files in PHP for comparing and analyzing data?

When comparing and analyzing data, using a database over processing CSV files in PHP offers several advantages. Databases provide faster data retrieval and querying capabilities, support for complex data relationships, data integrity through constraints and transactions, and scalability for handling large datasets. Additionally, databases offer built-in security features to protect sensitive information. 

// Connect to a MySQL database
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "database_name";

$conn = new mysqli($servername, $username, $password, $dbname);

// Query data from the database
$sql = "SELECT * FROM table_name WHERE condition = 'value'";
$result = $conn->query($sql);

if ($result->num_rows > 0) {
    // Output data of each row
    while($row = $result->fetch_assoc()) {
        echo "Column1: " . $row["column1"]. " - Column2: " . $row["column2"]. "<br>";
    }
} else {
    echo "0 results";
}

$conn->close();
