Restructure multidimensional array of column data into multidimensional array of row data [duplicate]

by

As Kris Roofe stated in his deleted answer, array_column is indeed a more elegant way. Just be sure to put it into some kind of a foreach loop, similar to what Sahil Gulati showed you. For example, like this:

$result = array();

foreach($where['id'] as $k => $v)
{
  $result[] = array_column($where, $k);
}

The var_dump output of $result is exactly what you’re looking for

array(3) {
  [0]=>
  array(2) {
    [0]=>
    int(12)
    [1]=>
    string(10) "1999-06-12"
  }
  [1]=>
  array(2) {
    [0]=>
    int(13)
    [1]=>
    string(10) "2000-03-21"
  }
  [2]=>
  array(2) {
    [0]=>
    int(14)
    [1]=>
    string(10) "2006-09-31"
  }
}
