Transposing multidimensional arrays in PHP
function transpose($array) { array_unshift($array, null); return call_user_func_array('array_map', $array);}Or if you're using PHP 5.6 or later:
function transpose($array) { return array_map(null, ...$array);}
With 2 loops.
function flipDiagonally($arr) { $out = array(); foreach ($arr as $key => $subarr) { foreach ($subarr as $subkey => $subvalue) { $out[$subkey][$key] = $subvalue; } } return $out;}
I think you're referring to the array transpose (columns become rows, rows become columns).
Here is a function that does it for you (source):
function array_transpose($array, $selectKey = false) { if (!is_array($array)) return false; $return = array(); foreach($array as $key => $value) { if (!is_array($value)) return $array; if ($selectKey) { if (isset($value[$selectKey])) $return[] = $value[$selectKey]; } else { foreach ($value as $key2 => $value2) { $return[$key2][$key] = $value2; } } } return $return;}
