Are there any best practices for managing memory usage in PHP when deleting objects and freeing up memory?

When deleting objects in PHP, it's important to unset any references to the object to allow the garbage collector to free up memory. Additionally, using unset() on large arrays or objects can help reclaim memory more efficiently. Implementing best practices for managing memory usage can help prevent memory leaks and optimize the performance of your PHP application.

// Example of unsetting objects and variables to free up memory
$object = new stdClass();
$object->data = "Some data";

// Unset the object to free up memory
unset($object);

// Example of unsetting large arrays to free up memory
$largeArray = range(1, 1000000);

// Unset the large array to free up memory
unset($largeArray);
