split array php from mysql

Question

i have array

Array
(
    [0] => Array
        (
            [question_id] => 13
            [is_break] => 0
        )
    [1] => Array
        (
            [question_id] => 14
            [is_break] => 1
        )
    [2] => Array
        (
            [question_id] => 15
            [is_break] => 0
        )
    [3] => Array
        (
            [question_id] => 16
            [is_break] => 1
        )
    [4] => Array
        (
            [question_id] => 17
            [is_break] => 1
        )
)

how to split by is_break = 1, so i have question_id (13,14)(15,16)(17) so i have 3 array that array [0] consist of question_id 13 and 14 array [1] consist of question_id 15 and 16 and array [2] consist of question_id 17

Please clear the question. You mean split by value of is_break? If so then your final result is wrong. — Parixit

In my answer you will get an array of n elements whose is_break=1. array[0] contain first element, array[1] second element and so on. — chanchal118

Try this...

$count = 0;
$result = array();
foreach($array as $a) {
    $result[$count][] = $a['question_id'];
    if($a['is_break']) {
        $count++;
    }
}

See Codepad.

Do something like this.. [FYI : This works on PHP >= 5.5 ]

$new_array = array_chunk(array_column($your_array,'question_id'),2);
var_dump($new_array);

$questions = array();

foreach ($main_array as $subarray) {
   if($subarray['is_break'] == 1) {
       array_push($questions, $subarray['question_id']);
   }
}

Now $questions array has the question ids.

This will only return question_id having is_break = 1.
