Rearrange an array according to key

问题

I dont know what to ask so i straight away went to show an example. Hope it helps though! Say i have an array

array (size=3)
  0 => 
    array (size=3)
      0 => int 1
      1 => int 2
      2 => int 3
  2 => 
    array (size=3)
      0 => int 2
      1 => int 3
      2 => int 4
  5 => 
    array (size=3)
      0 => int 5
      1 => int 6
      2 => int 7

Now i want to arrange it according to KEY so that it looks like

array (size=3)
  0 => 
    array (size=3)
      0 => int 1
      1 => int 2
      2 => int 3
  1 => 
    array (size=3)
      0 => int 2
      1 => int 3
      2 => int 4
  2 => 
    array (size=3)
      0 => int 5
      1 => int 6
      2 => int 7

Does anyone has a solution ?

回答1:

One possible approach:

$new_arr = array_values($old_arr);

回答2:

You can use foreach and assign the values to new array

$newArr = array();
foreach($array as $k=>$v){
    $newArr[] = $v;
}

回答3:

The most direct way to achieve that is probably to run array_values on your array :

$array = array_values($array);

It will basically reset the keys
