What is the best way to handle file operations like opening and reading CSV files in PHP?

When handling file operations like opening and reading CSV files in PHP, it is best to use the built-in functions provided by PHP such as fopen() to open the file and fgetcsv() to read the contents of the CSV file line by line. This allows for efficient and reliable file handling without the need for external libraries.

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

// Read the CSV file line by line
while (($data = fgetcsv($csvFile)) !== false) {
    // Process the data as needed
    print_r($data);
}

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