The most portable way is storing as text, but this is nearly out of
the question efficiency-wise for large multidimensional arrays.

The second most portable way is to serialize your binary arrays.
This means outputting them 8 bits at a time, using shift operators to
break the data items up into bytes.  To read them back, reassemble
the bytes back into data items.

The least portable way (fwrite()/fread()) is deprecated because it
causes problems with alignment and endianness when files are moved
between architectures.
