Saving arrays in file

[ppera]

Is there some (elegant) way to save arrays directly in files?
I solved it so that I saved content as string, and when use it in script I convert back to array with explode.
Of course there is need for load arrays too.

You may use serialize function:
$a = serialize(array);
and save into file.
but if you need red from file use unserialize

P.S.
In this situation to you not need use exploede.....
