What are some best practices for handling server load monitoring in PHP scripts, considering different PHP configuration settings?

When monitoring server load in PHP scripts, it's important to consider the impact of different PHP configuration settings on the accuracy of the monitoring. One best practice is to use functions like `sys_getloadavg()` to retrieve the system load average, which can provide valuable insights into server performance. Additionally, adjusting PHP settings such as `max_execution_time` and `memory_limit` can help prevent script timeouts and memory exhaustion during load monitoring.

// Get the system load average
$loadAvg = sys_getloadavg();

// Display the load average
echo "Load Average: " . implode(', ', $loadAvg);
