What are the potential drawbacks of manually tracking and managing access codes for online surveys or tests?

Manually tracking and managing access codes for online surveys or tests can be time-consuming and prone to errors. It can also lead to security risks if access codes are shared or leaked. To solve this issue, it is recommended to automate the generation and distribution of access codes using a secure and reliable system. 

// Generate a random access code for the survey or test
$access_code = bin2hex(random_bytes(6));

// Save the access code in a database or file for future reference
// Make sure to encrypt or hash the access code for security
