How can the use of trim function improve the handling of CSV files in PHP?

When working with CSV files in PHP, leading or trailing whitespaces in the data can cause issues when processing the file. Using the trim() function can help remove these unwanted whitespaces, ensuring that the data is clean and properly formatted for further processing. 

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

// Loop through each row in the CSV file
while (($data = fgetcsv($file)) !== false) {
    // Trim each value in the row to remove any leading or trailing whitespaces
    $cleanedData = array_map('trim', $data);
    
    // Process the cleaned data as needed
    // ...
}

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