What are some functions in PHP that can be used to read and manipulate CSV files?

To read and manipulate CSV files in PHP, you can use functions like fopen(), fgetcsv(), and fputcsv(). The fopen() function is used to open the CSV file, fgetcsv() is used to read each line of the CSV file as an array, and fputcsv() is used to write an array as a line in the CSV file. 

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

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

// Close the CSV file
fclose($csvFile);
