Are there any other methods or techniques to restrict access to scripts run via Cron jobs in PHP, apart from those mentioned in the forum thread?

To restrict access to scripts run via Cron jobs in PHP, one method is to check the request headers for a specific value that only Cron jobs would have. Another technique is to use a secret token that needs to be included in the request to the script.

// Check for specific request header
if (!isset($_SERVER['HTTP_X_CRON_HEADER'])) {
    die('Access denied');
}

// Use a secret token
$secret_token = 'your_secret_token_here';
if ($_GET['token'] !== $secret_token) {
    die('Access denied');
}

// Your script code here
