PHP：如何获得密钥的最低数组值

Question

I have a an array and I need to get the lowest value together of key. Because i need to check if the value has contain the right key or not

 Array ( 
      [120] => 97.00 
      [132] => 92.67 
      [124] => 72.33 
      [131] => 49.67 
      [129] => 25.00 
      [127] => 25.00 //<--Get the value and this key
  )
  //This array already sorted, no need to sort just get the last value and key

How can i get the lowest value 25.00 together the key [127]

 $array = array (

      "120" => 97.00 
      "132" => 92.67 
      "124" => 72.33 
      "131" => 49.67 
      "129" => 25.00 
      "127" => 25.00 

  );

  print_r(min($array)); //<--displaying only the value but not the key

The output should be like

127 - 25.00

Answer 1

$array = array (
      "120" => 97.00, 
      "132" => 92.67,
      "124" => 72.33,
      "131" => 49.67,
      "129" => 25.00,
      "127" => 25.00 

  );
    // point the last element of the element and fetch value to $value
    $value= (end($array));
    // fetch key
    echo "key : ". key($array);
    echo "value :".$value;
