Well, print_r() simply iterates the array and prints it.... so if
you just want the array, skip print_r() entirely and use the variable
you were passing to it.

There's plenty of ways to parse strings into arrays, it just
depends on how you want to do it. For one example, if you wanted to
split each word into an individual array value, you could do:
<?php
$sentence = "This is a test.";
$words = explode(' ',$sentence);
/*
Then $words would contain:
[0] => This
[1] => is
[2] => a
[3] => test.
*/
?>
Then, say you wanted to shuffle the words around, and then convert
them back to an array. I don't know why, just say it.... out loud.
I'll wait.
Nevermind, here's the example anyway:
<?php
// From $words in the previous example....
shuffle($words);
$sentence = implode(' ',$words);
?>
The latter example will mix up the words and put them back into a
sentence, with a whitespace (' ') as the "glue" between them.
