What is the recommended method in PHP to export query results to a text file quickly?

When exporting query results to a text file in PHP, the recommended method for quick and efficient export is to use the fopen function to open a file handle, fetch the query results, and then write them to the file using fwrite. This method allows for direct writing of data to the file without the need to store the entire result set in memory. 

// Connect to the database
$connection = mysqli_connect("localhost", "username", "password", "database");

// Open a file handle for writing
$file = fopen("output.txt", "w");

// Perform a query
$query = "SELECT * FROM table";
$result = mysqli_query($connection, $query);

// Loop through the results and write them to the file
while ($row = mysqli_fetch_assoc($result)) {
    fwrite($file, implode("\t", $row) . "\n");
}

// Close the file handle and database connection
fclose($file);
mysqli_close($connection);
