In what scenarios would using the "SELECT ... INTO OUTFILE ..." method in PHP be more advantageous than using loops for exporting data to a text file?

Using the "SELECT ... INTO OUTFILE ..." method in PHP can be more advantageous than using loops for exporting data to a text file when you want to quickly export large amounts of data from a database table to a text file without having to iterate over each row individually. This method allows you to directly export the result set of a SQL query to a text file in a single step, which can be more efficient and faster for large datasets. 

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

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

// Run the SQL query and export the result set to a text file
$sql = "SELECT * INTO OUTFILE '/path/to/outputfile.txt' FIELDS TERMINATED BY ',' LINES TERMINATED BY '\n' FROM your_table";
if ($conn->query($sql) === TRUE) {
    echo "Data exported successfully to outputfile.txt";
} else {
    echo "Error exporting data: " . $conn->error;
}

// Close the database connection
$conn->close();
