是否有PHP函数来编码/解码字符串中的多维数组？

Question

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.

Answer 1

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.
