What are the best practices for customizing PHP code to suit specific website requirements, such as storing email addresses in a text file instead of a database?

When customizing PHP code to store email addresses in a text file instead of a database, you can create a function that reads and writes email addresses to a text file. This can be useful for small-scale websites or projects where a database is not necessary. To implement this, you can use PHP's file handling functions like fopen(), fwrite(), and fclose() to manage the text file. 

// Function to add email address to text file
function addEmailToFile($email) {
    $file = 'emails.txt';
    $current = file_get_contents($file);
    $current .= $email . "\n";
    file_put_contents($file, $current);
}

// Example of adding an email address to the text file
$email = 'example@email.com';
addEmailToFile($email);
