是否有PHP函数来编码/解码字符串中的多维数组？
Is there a PHP function to encode a generic multidimensional array as a string and get it back as a multidimensional array?
I need it to store in mysql some data (a drupal computed field to be precise). The array contains just floats and strings.

serialize() and unserialize() do what you describe.

You could also consider encoding the array as JSON with json_encode() and json_decode(), which gives more readable output, if that is important to you.
I second the use of "json_encode" and "json_decode". I believe the output of "json_encode" is less verbose than PHP's serialize function (since data types are inferred) and is immediately more portable (even though that is not a requirement).
Make sure you pass "TRUE" for the second parameter of "json_decode", otherwise you may get a simple object back, depending on how the original data was encoded.
