The easiest way is to JSON-encode your object and then decode it back to an array    array   json decode json encode  object   true     Or if you prefer  you can traverse the object manually  too   foreach   object as  value        array      value- gt post id

if you have an array and array element is stdClass item then this is the solution   foreach  post id as  key  gt  item        post id  key     array  item      now the stdClass has been replaced with an array inside the array as new array element
