Question

i’m trying to implode an array using:

  $implode_keys = implode(',', array_values($arr)
   $implode_values = implode(',', array_keys($arr)

Answer 1

serialize the array (or array of arrays). That’s what serialization is intended for. When you need it back as an array (or array of arrays)… just unserialize it.

For future generations… serialization flattens out a data structure, such as an array, so that it may be stored in a simplified fashion, such as in a database.
