Delete the first identifier levels in an array

Question

I think it was before, but could not find an answer to it. If he already answered, point me in the right direction link.

I have an array that I would not delete from the first level of the identifier. I think there is a function for this?

An example of how to do this:

[0] => Array
        (
            [8] => Röd
        )

[1] => Array
        (
            [8] => Blå
        )

[2] => Array
        (
            [6] => Bobo
        )

[3] => Array
        (
            [8] => Grön
        )

[4] => Array
        (
            [7] => Sten
        )

[5] => Array
        (
            [8] => Vit
        )

[6] => Array
        (
            [7] => Guld
        )

[7] => Array
        (
            [6] => Lyxig
        )

What i wan't

[8] => Röd
[8] => Blå
[6] => Bobo
[8] => Grön
[7] => Sten
[8] => Vit
[7] => Guld
[6] => Lyxig

Answer 1

The problem here is storing keys for the required identifier. You have strings with names that have the same key (e.g. Blå and Röd). You need to either save them in an array, or want to lose the key.

Example with php5.3:

$processed = array_map(function($a) {  return array_pop($a); }, $arr);

This will give you:

[0] => Röd
[1] => Blå
[2] => Bobo
[3] => Grön
[4] => Sten
[5] => Vit
[6] => Guld
[7] => Lyxig

, , . , , 2 . :

[8] => Array
        (
            [0] => Röd,
            [1] => Blå,
            [2] => Vit,
            [3] => Grön
        )

[6] => Array
        (
            [0] => Bobo,
            [1] => Lyxig
        )

[7] => Array
        (
            [0] => Sten,
            [1] => Guld
        )

, :

$processed = array();
foreach($arr as $subarr) {
   foreach($subarr as $id => $value) {
      if(!isset($processed[$id])) {
         $processed[$id] = array();
      }

      $processed[$id][] = $value;
   }
}

Answer 2

PHP array_column

$new_array = array_column($old_array,0);

0 $old_array. .

Answer 3

:

  public function remove_level($array) {
      $result = array();
      foreach ($array as $key => $value) {
        if (is_array($value)) {
          $result = array_merge($result, $value);
        }
      }
      return $result;
}

. array_walk

   $results = array();
   array_walk($array, function($v, $k) use($key, &$val){
              array_merge($results, $v);
    });

Answer 4

foreach($array as $key=>$val) { 
  $newarr[$val] = $array[$key][$val]; 
}

Answer 5

,

<?php
$arrData = array(
"5" => array
        (
            "8" => "Vit"
        ),

"6" => array
        (
            "7" => "Guld"
        )
);
foreach($arrData as $key=>$value):
    foreach($value as $k=>$v):
     $data[$k] = implode(',',$arrData[$key]);
    endforeach;
endforeach;


print_r($data);
?>

Answer 6

splat:

   print_r(array_merge(...$array));
