HTML to PHP arrays -

good evening everyone,

i've been searching , trying while build small program, want user input unknown amount of numbers (he can enter as like), , want make array out of them, everywhere on internet keeps using many "input type="text"...." boxes don't know how many user input.and don't want page keep refreshing if possible i'd send numbers @ once same page or page, create array out of them can complete program using functions based on array.

edit: first used <form action="process.php" method=post> insert values here: <input type="number" name=num><br> <input type="submit" value="send"> </form>

and didn't know after read files , used piece of code , worked. thank member answered using jquery yet learn java couldn't use now. started last year software engineering student , still don't know , understand embarrassed when read codes others , don't understand

` $h = fopen("numtext.txt", "r");

if($h) {     while (($data = fgetcsv($h, 1000, " ")) !== false) {         foreach($data $num)             $numbers[] = $num;     }     fclose($h); }  print_r($numbers); echo count($numbers);` 

here simple approach using jquery

var inputhandler = function( $el ){    var t = this;    this.$el = $el;    this.sendtoserverbutton = $el.find("button.sendtoserver");      var newinputelement = '<input type="text" /><br>';      this.$el.append(newinputelement);          /**      on enter:        add newinputelement ,        change focus new    **/    this.$el.on("keyup", "input", function(e){      if (e.which !== 13) {        return false;      }      t.$el.append(newinputelement);      t.$el.find("input:last").focus();    });          /**      send backend "script.php" "stringify" array    **/    this.sendtoserver = function(numberarray){        console.log("sending numbers server: ", numberarray);      var stringforserver = json.stringify(numberarray);            $.ajax({        url: "script.php",        type: "post",        data: ({numberarraystring : stringforserver}),        success: function(msg){          alert("send server" + msg);        }      });          /**        on server side in php (above called "script.php") do:        $numberarray= json_decode($_post['numberarraystring']); // create php array stringify-json string      **/      }          /**      on click:        collect numbers input fields , send them server    **/    this.sendtoserverbutton.on("click", function(){      var numbers = [];      $el.find("input").each(function(){        var numberasstring = $(this).val();        var number = parseint(numberasstring);        numbers.push( number );      });      t.sendtoserver(numbers);    });    }      var inputhandler = new inputhandler( $(".inputs") );

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>    <p>    enter numbers in input field.     press enter add additional numbers.  </p>  <div class="inputs">    <button class="sendtoserver">send server</button><br>  </div>
