How does the memory_get_usage() function in PHP help in understanding memory allocation and release when working with objects?

The memory_get_usage() function in PHP helps in understanding memory allocation and release when working with objects by providing information about the amount of memory currently being used by the script. This can be useful for identifying memory leaks or optimizing memory usage in your code.

// Get initial memory usage
$initialMemory = memory_get_usage();

// Create and work with objects here

// Get memory usage after working with objects
$finalMemory = memory_get_usage();

// Calculate memory usage difference
$memoryUsed = $finalMemory - $initialMemory;

echo "Memory used: " . $memoryUsed . " bytes";
