here question list

 array (  [0] => 4e28258262d100 [1] => 4e282582649464 [2] => 4e28258265b752  [3] => 4e282582674ba0 [4] => 4e282582689e80 )      foreach($questionlist $question){         // want answers in array above          // has $question.question_id = question_id_fk . 1 question can have multiple         // answers  //print each question id  //print answer , result_text , correct values answers found answerlist       } 

how search answers question id array . need "correct" , "result_text" values answer .

$matches = array_filter ($answerlist, function ($answer) use ($question) {   return $question['id'] == $answer['question_id_fk']; }); 

now can access every single entry.

if want reduce structures array of primtive values (the values looking for) ca like

$correct = array_reduce(   $matches,    function ($result, $current) {     $result[] = $current['correct'];     return $result;   },    array() );

update

i suggest reorder $answerlist

$answerlistorderedbyquestionid = array_reduce (   $answerlist,    function ($result, $answer) {     if (!array_key_exists($answer['question_id_fk'], $result))       $result[$answer['question_id_fk']] = array();      $result[$answer['question_id_fk']][] = $answer;      return $result;   },    array() ); 

this should associative array key question-id. can access every single answer given question.
