I've never written anything in PHP here so I might be way off...But a
16MB memory limitation would only stop you from reading the entire
file into memory at once.
The way I'd do would be to read/encrypt/write N blocks at a time.
[This is similar in principle to what you're doing, except without the
need for separate files or reinitialization of the block cipher mode.]

Sorry for the late answer. You are right. I can do it your way but
there is still another problem. PHP scripts normally timeout after
30seconds due to security reasons. So, I cannot encrypt/decrypt large
files. Because of that I split the file.
