php - Getting x amount of items from array -

-

i'm doing task in school i'm arrays , loops in php.

what i've done far make piece of code, makes array names separate text-file, , chooses random name array.

what i'd display x amount of random names. amount of names can chosen in input field, preferably or while loop (those ones know somewhat).

here code (don't think text-file necessary. if is, let me know):

<form method="post">     how many names need?      <input type="number" name="amount" min="1" max="28"><br><br>    <input type="submit" name="proceed" value="get name(s)"> </form>  <?php            $text = file_get_contents("names2t.txt");      $array = explode("\n", $text);      $randnamenum = array_rand($array);      $randphrase = $array[$randnamenum];       if (isset($_post["proceed"])){         echo $randphrase;     }    ?>

is possible i'm asking?

just add field on form , loop on :

    <form method="post">         how many names need?  <input type="number" name="amount" min="1" max="28"><br>         how many times? <input type="number" name="repeat-count"><br>         <input type="submit" name="proceed" value="get name(s)">      </form>      <?php             if(isset($_post['proceed'])) {         for($i = 0; $i < $_post['repeat-count']; $i++) {             $text = file_get_contents("names2t.txt");              $array = explode("\n", $text);              $randnamenum = array_rand($array);              echo $array[$randnamenum];          }     }        ?>
