What are the potential pitfalls of not properly handling missing values or errors when processing CSV files in PHP?

If missing values or errors are not properly handled when processing CSV files in PHP, it can lead to unexpected behavior, incorrect data processing, or even application crashes. To avoid these pitfalls, it is important to check for missing values and errors before processing the data. 

$csvFile = 'data.csv';

if (($handle = fopen($csvFile, 'r')) !== FALSE) {
    while (($data = fgetcsv($handle, 1000, ',')) !== FALSE) {
        // Check for missing values or errors before processing the data
        if (in_array('', $data)) {
            // Handle missing values or errors here
            continue;
        }
        
        // Process the data
        // Your code here
    }
    fclose($handle);
}
