Are there any best practices for handling CSV data in PHP?

When handling CSV data in PHP, it is important to use built-in functions like `fgetcsv()` to properly parse the data and handle any potential issues such as escaping characters or handling different delimiters. It is also recommended to sanitize and validate the data before processing it further to prevent any security vulnerabilities. 

// Example of reading and processing CSV data in PHP
$filename = 'data.csv';
$handle = fopen($filename, 'r');

if ($handle !== false) {
    while (($data = fgetcsv($handle)) !== false) {
        // Process each row of CSV data here
        // Example: echo implode(', ', $data) . PHP_EOL;
    }

    fclose($handle);
} else {
    echo 'Error opening file.';
}
