I believe serialize is usually used in cases like this:
http://www.php.net/manual/en/function.serialize.php
A while back, I wrote a function called array_smart_dump (yes, the
name makes me giggle, too) that accomplishes the same thing with
arrays a bit more literally.
It will convert an array to a string that, as I put it, is
syntactically usable, meaning you can write the string (enclosed by
appropriate php tags) to file and then later use that array by simply
including the file.
The code can be found here:
http://klenwell.googlecode.com/svn/trunk/PHP/array/array_smart_dump.inc.php
Here's a test script:
