Are there any specific PHP functions or libraries that can simplify the process of parsing and manipulating CSV data?

Parsing and manipulating CSV data in PHP can be simplified by using the built-in `fgetcsv()` function to read each line of the CSV file and automatically parse it into an array. Additionally, the `str_getcsv()` function can be used to parse a CSV string into an array. To manipulate the CSV data, you can use array functions like `array_map()` or `array_filter()` to process the data as needed.

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

// Loop through each line of the CSV file and parse it into an array
while (($data = fgetcsv($file)) !== false) {
    // Manipulate the CSV data as needed
    $processedData = array_map('strtolower', $data);
    
    // Output the processed data
    print_r($processedData);
}

// Close the file
fclose($file);
