How can debugging PHP code for HTML email generation be improved?

Issue: Debugging PHP code for HTML email generation can be improved by using error handling techniques such as try-catch blocks and logging errors to a file. This allows for better tracking and identification of issues in the code.

<?php

// Set error reporting level to catch all errors
error_reporting(E_ALL);

// Set error handling to log errors to a file
ini_set('log_errors', 1);
ini_set('error_log', 'error.log');

try {
    // Your HTML email generation code here
} catch (Exception $e) {
    // Log any errors to the error log file
    error_log($e->getMessage());
}

?>
