What are some potential pitfalls when using fgetcsv to extract version strings from files in PHP?

One potential pitfall when using fgetcsv to extract version strings from files in PHP is that the version string might not be in the expected column or format, leading to incorrect results. To address this issue, you can check each row to ensure it contains the version string in the correct format before extracting it. 

$file = fopen('versions.csv', 'r');

while (($data = fgetcsv($file)) !== false) {
    // Check if the row contains the version string in the expected format
    if (isset($data[1]) && preg_match('/^\d+\.\d+\.\d+$/', $data[1])) {
        $version = $data[1];
        echo $version . PHP_EOL;
    } else {
        echo "Invalid version string found" . PHP_EOL;
    }
}

fclose($file);
