How can one ensure that the script waits for the CSV file to be fully loaded before proceeding with further processing in PHP?

To ensure that the script waits for the CSV file to be fully loaded before proceeding with further processing in PHP, you can use the `flock()` function to lock the file until it is fully loaded. This will prevent the script from reading the file before it is ready. 

$filename = 'data.csv';
$handle = fopen($filename, 'r');

if (flock($handle, LOCK_SH)) {
    // File is locked, proceed with further processing
    while (($data = fgetcsv($handle)) !== false) {
        // Process the data from the CSV file
    }

    flock($handle, LOCK_UN); // Release the lock
} else {
    echo "Could not lock the file!";
}

fclose($handle);
