What are the potential risks and benefits of automating the deployment of PHP code using cronjobs or CI servers?

Automating the deployment of PHP code using cronjobs or CI servers can have both risks and benefits. The benefits include improved efficiency, consistency, and reduced human error in the deployment process. However, the risks involve potential security vulnerabilities if not properly configured, as well as the possibility of unintended consequences if the automation is not thoroughly tested. 

// Example of a PHP script to automate deployment using cronjob
// Ensure that the script is secure and only accessible by authorized users

<?php

// Check if the request is coming from an authorized source
$authorized_sources = ['127.0.0.1', 'localhost']; // Update with actual authorized sources

if (!in_array($_SERVER['REMOTE_ADDR'], $authorized_sources)) {
    http_response_code(403);
    exit('Unauthorized access');
}

// Add deployment logic here
// For example, execute shell commands to pull the latest code from the repository and restart the server

// Log the deployment activity
$log_message = 'Deployment successful at ' . date('Y-m-d H:i:s') . ' by ' . $_SERVER['REMOTE_ADDR'] . PHP_EOL;
file_put_contents('deployment.log', $log_message, FILE_APPEND);

echo 'Deployment successful';
