从数组PHP中回显特定值?

I need to insert specific array values in a HTML form. I query, fetch and array from a mysql table. When I print_r($array) I get the below output.

Question: Let´s say I want to echo out the value Dæk Bag to a html form question, how do I do that?

INFO: I have 40 questions in the form.

Ps. The app is for own use only, and I am aware of the use of mySQLi or PDO instead of mySQL -> It will be change asap.

Array:

Array
(
    [0] => 1
    [id] => 1
    [1] => Dæk For
    [title_task_DK] => Dæk For
)
Array
(
    [0] => 2
    [id] => 2
    [1] => Dæk Bag
    [title_task_DK] => Dæk Bag
)
Array
(
    [0] => 3
    [id] => 3
    [1] => Dæk Alm.
    [title_task_DK] => Dæk Alm.
)
Array
(
    [0] => 4
    [id] => 4
    [1] => Dæk Indl.
    [title_task_DK] => Dæk Indl.
)
Array
(
    [0] => 5
    [id] => 5
    [1] => Slange/Lapning For
    [title_task_DK] => Slange/Lapning For
)

My PHP code:

<?php
$results = mysql_query("SELECT * FROM task_list");
    while($array = mysql_fetch_array($results)) {    
        print_r($array);
    }
?>

My mySQL table:

CREATE TABLE `task_list` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `title_task_DK` varchar(255) NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=37 DEFAULT CHARSET=utf8;

    The below PHP code solved my question and echos out the wanted value Dæk Bag I needed in my HTML form.

    <?php
     $results = mysql_query("SELECT * FROM task_list");
     $value = array();
     while($array = mysql_fetch_array($results)) {    
      $value[] = $array['title_task_DK'];
    }
      echo($value[1]);
    ?>
    

    Do you need a foreach loop in the above code: I found this Stack Overflow link helpful.

    Thank you all for commenting and answering.

    Ps. that said, please read: Why shouldn't I use mysql_* functions in PHP?.
