Releasing a variable from memory.

[hankjrfan]

I am planning on writeing a larg script that will use several large arrays. I was just curious to know if there is a way to release an array or variable from memory so that it does not stay their needlessly. I greatly apologize if this is easly found in the manual or another post.

Thanks

To erase an array (maybe because it is a large global array and you want to free the memory), simply assign a single value to it:

$array = 0

This will free the array and convert it back to the single value of 0.
