What are some common pitfalls when working with CSV data in PHP?

One common pitfall when working with CSV data in PHP is not handling special characters properly, which can lead to data corruption or parsing errors. To solve this issue, it's important to properly encode and decode the CSV data using functions like `utf8_encode()` and `utf8_decode()`.

// Example of properly encoding and decoding CSV data
$csvData = "Name,Age,City\nJohn,Doe,30\nJane,Doe,25\n";
$encodedData = utf8_encode($csvData);

// To decode the data back to its original form
$decodedData = utf8_decode($encodedData);
echo $decodedData;
