What is the recommended method for monitoring server activities in PHP?

Monitoring server activities in PHP can be done using a combination of log files, monitoring tools, and custom scripts. One recommended method is to use a combination of PHP functions like error_log() to log specific events or errors, and tools like New Relic or Datadog to monitor server performance and track metrics in real-time.

// Example of logging server activities using error_log()
error_log('Server activity: Request received at ' . date('Y-m-d H:i:s'));

// Example of monitoring server performance using New Relic
newrelic_add_custom_parameter('Server Activity', 'Request received');

// Example of monitoring server metrics using Datadog
$statsd = new Datadog\Statsd();
$statsd->increment('server.activity.request_received');
