What functions can be used to parse CSV data in PHP?

To parse CSV data in PHP, you can use the built-in functions like `fgetcsv()` or `str_getcsv()`. `fgetcsv()` is used to read a line from an open file pointer and parse it as CSV fields, while `str_getcsv()` is used to parse a CSV string into an array. These functions handle parsing CSV data by correctly handling fields containing commas or double quotes.

// Example using fgetcsv() to parse CSV data from a file
$csvFile = fopen('data.csv', 'r');
while (($data = fgetcsv($csvFile)) !== false) {
    // $data is an array containing the CSV fields for each row
    print_r($data);
}
fclose($csvFile);
