How can fopen function be used to manage "Beta-codes" in a PHP project?

To manage "Beta-codes" in a PHP project using the fopen function, you can create a text file to store the codes. You can use fopen to open the file in read or write mode, depending on whether you are generating new codes or checking existing ones. You can then use fgets to read the codes from the file and fclose to close the file when you are done. 

// Open the file for reading
$betaCodesFile = fopen("beta_codes.txt", "r");

// Read each line in the file
while(!feof($betaCodesFile)) {
    $betaCode = fgets($betaCodesFile);
    // Do something with the beta code
}

// Close the file
fclose($betaCodesFile);
