Monitoring CPU and memory usage in PHP is crucial for optimizing performance. Here are some techniques you can use to track CPU and memory usage within your PHP code:
$memoryUsage = memory_get_usage(); // Memory usage in bytes echo "Memory Usage: " . $memoryUsage . " bytes";
$peakMemoryUsage = memory_get_peak_usage(); // Peak memory usage in bytes echo "Peak Memory Usage: " . $peakMemoryUsage . " bytes";
$resourceUsage = getrusage(); $cpuUsage = $resourceUsage['ru_utime.tv_usec'] + $resourceUsage['ru_stime.tv_usec']; // CPU usage in microseconds echo "CPU Usage: " . $cpuUsage . " microseconds";
Remember that CPU and memory usage may vary depending on the server environment and other factors. The techniques above provide a general approach to measuring CPU and memory usage within a PHP script. Implementing these methods can aid in optimizing your application's performance.
