Probably better to initialize it to an empty array();...

... since you are going to initialize it to an array here anyway.

Buffering 10 lines of text in PHP is probably not going to make a
significant difference...

You'll have to test on your hardware to confirm, but between:

1. Low-level disk IDE buffer
2. Operating System disk cache buffers
3. C code of PHP source disk cache buffers

your PHP 10-line buffer in an array
is probably more overhead, and much more complicted code to maintain,
with no significant benefit.
