What are the best practices for handling CSV data in PHP to avoid errors during import?

When handling CSV data in PHP, it is important to properly sanitize and validate the data to avoid errors during import. One way to do this is by using the fgetcsv() function to read the CSV file line by line and then validating each row of data before processing it. Additionally, it is recommended to use try-catch blocks to handle any potential errors that may occur during the import process. 

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

try {
    // Loop through each row of the CSV file
    while (($data = fgetcsv($file)) !== false) {
        // Validate and sanitize the data before processing
        $validatedData = validateAndSanitizeData($data);

        // Process the validated data
        processData($validatedData);
    }
} catch (Exception $e) {
    // Handle any errors that occur during the import process
    echo 'Error: ' . $e->getMessage();
}

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

// Function to validate and sanitize the data
function validateAndSanitizeData($data) {
    // Add your validation and sanitization logic here
    return $data;
}

// Function to process the data
function processData($data) {
    // Add your data processing logic here
}
