this pulls out 1024 bytes of data form the file. right?
or does this pull UPTO 1024 bytes of data or the EOL, which ever is first?

OK. $tempMap is a string var. Each line of the file has a /n delimiting it.
Now make an array of these line.
Right?

walk down the map array.
split each element on the SPACE, but don't deal with blank lines
...
seems almost the same.
nice use of PREG_SPLIT. I guess that helps with the BLANK lines.
if fgets() onlt pulls out so much data, not to EOL, why use it?
If I understand right, if I pull out 1028 of data, the '#' on each line
could be anywhere in that buffer, not just at the first character.
That's why I pulled in the entire file into a string var and then exploded
it into an array split on EOL characters.
Am I missing something?
Thanks for your sample.
