i trying figure out how save indexed array field in database. said, know array can't saved database, can serialize or implode , save. im not sure 1 should using though. don't want collection of items saved in 1 cell. need list of items saved 1 one in column. question need using serialize method, implode or else? here glimpse of code , array trying save.

 public function findpolicyids($coverageid = null) {     $policyid = $this->policy->find('all', array(         'recursive' => -1,         'conditions' => array('policy.coverage_id' => $coverageid),         'fields' => array('policy.id')));          foreach($policyid $id) {             $all[] = $id['policy']['id'];             }         return $all; }    array ( [0] => 5202834f-111c-4a76-8b33-1ed8ae78509d [1] => 5202834f-2ba8-4957-91db-1ed8ae78509d [2] => 5202834f-356c-49a1-beeb-1ed8ae78509d [3] => 5202834f-3b40-453f-a491-1ed8ae78509d 

it depends.

this best answer give you.

do whatever like, long doesn't magically corrupt data between write , read.

lemme take moment explore few options on behalf.

• var_export() - might not best idea, securitywise
• serialize() - seems straightforward
• implode() - seems straightforward
• json_encode() - seems straightforward

there other, more obscure, options available. build complex data sets xml, if like.

alternatively, why not normalize schema , add new table present collections of array-data ? normalization tends save bacon in future.
