How does the use of functions like file and fopen contribute to efficiently handling CSV files in PHP?

To efficiently handle CSV files in PHP, functions like `file` and `fopen` can be used to read and write to the file. The `file` function reads the entire file into an array, making it easy to loop through each line of the CSV file. The `fopen` function is used to open a file for reading or writing, allowing for more control over the file handling process. 

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

// Loop through each line of the CSV file
while (($data = fgetcsv($file)) !== false) {
    // Process each row of data
    print_r($data);
}

// Close the file
fclose($file);
