php - get_post_meta() returning an arrary when it shouldn't -

-

why using get_post_meta() of sudden start returning array when $single set true?

$sync = get_post_meta( $pid, '_subscription_sync', true ); if ( 'yes' != $sync )     return;

var_dump($sync) returns this: array(1) { [0]=> string(3) "yes" }

is there global setting i'm not aware off?

you have saved array database. update_post_meta automatically serializes you. $single setting on get_post_meta refers whether pull entries post id , key..

var_dump variable saving before update_post_meta , check how ending array.
