我如何打印像数组一样的数组（[2] => 4，[6] => 8，[5] => 7）

I have been given array like

array(2,4,5,6,7,8).

Now I was asked to do some array operation which will give me output as

array([2]=>4,[6]=>8,[5]=>7)

Try this..

  <?php

$array=array("2"=>4,"6"=>8,"5"=>7);

$data=array_keys($array);
$data1=array_values($array);
$result = array_merge($data, $data1);
sort($result);
print_r($result);

?>

Output:Array ( [0] => 2 [1] => 4 [2] => 5 [3] => 6 [4] => 7 [5] => 8 )
