Solved PocketMine memory free

How do PocketMine handle variable?
For example if i assign $data in function for a freaking long string that take 3mb of RAM, will it automatically free up when i leave that function? Or i have to unset($data) or assign $data = null ?

Better unset it. And PocketMine handles NOTHING. PHP does the work.

Of course it does unset variables that are on function scope

PHP:

<?php
function bla(){
$string = "BLABLABLABLABLABLA";
}
bla();
//No memory leak here


If the variable isn't being used anymore, the garbage collector will free the associated memory. Using unset() will not immediately remove the variable from memory, but will mark the memory associated with the variable to be freed when the garbage collector runs. Seting the variable to null will overwrite the data immediately, freeing the previous memory.
