What are some common pitfalls to avoid when using fgetcsv function in PHP?

One common pitfall to avoid when using the fgetcsv function in PHP is not properly handling the return value. The function returns false if it reaches the end of the file or encounters an error, so it's important to check for this condition before processing the data. Additionally, make sure to set the correct delimiter and enclosure parameters to match the CSV file format to avoid parsing errors. 

// Correct way to use fgetcsv function with error handling
$handle = fopen("file.csv", "r");

if ($handle !== false) {
    while (($data = fgetcsv($handle, 0, ',', '"')) !== false) {
        // Process the CSV data here
    }

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