What PHP functions or techniques are recommended for handling CSV files efficiently?

When handling CSV files in PHP, it is recommended to use the built-in functions like `fgetcsv()` to efficiently read and parse the data from the file. Additionally, using functions like `fopen()` and `fclose()` to open and close the file handle can help improve performance. It is also advisable to use proper error handling techniques to manage any issues that may arise during the file handling process. 

// Open the CSV file for reading
$file = fopen('data.csv', 'r');

// Read and parse each line of the CSV file
while (($data = fgetcsv($file)) !== false) {
    // Process the data as needed
    print_r($data);
}

// Close the file handle
fclose($file);
