How to export html form to csv file

Question

I am trying to create a form in which the user can enter data, and then, when they click the "Submit" button, this data will be added in a new line to the csv file stored on the server that I can upload. I tried both some php files and javascript, both of which seem to be good, but I am also not very experienced.

Here is the basic html form:

<form name="xyz_form">
    <section class="border-bottom">
<div class="content">
    <h3>ID Number</h3>
    <div class="form-control-group">
        <div class="form-control form-control-number">
            <input type="number" id="id_number">
        </div>
    </div>
            <h3>First Name</h3>
    <div class="form-control-group">
        <div class="form-control form-control-text">
            <input type="text" id="first_name">
        </div>
    </div>
</div><!--.content-->
    <section class="data-capture-buttons one-buttons">
       <div class="content">
          <input type="submit" value="Submit" onClick="javascript:addToCSVFile()">
       </div>
    </section><!--.data-capture-buttons-->

Javascript is in the header of the html file, and it is:

<script type="text/javascript">
        function addToCSVFile() {
            var csvData = new Array();  // To collect the names
            var csvFilePath = "Data.csv"; // File name

            // Collect General Information
            csvData[0] = document.getElementById('id_number').value;
            csvData[1] = document.getElementById('first_name').value;

              var fso = new ActiveXObject('Scripting.FileSystemObject');
            var oStream = fso.OpenTextFile(csvFilePath, 8, true, 0);
            oStream.WriteLine(csvData.join(','));
            oStream.Close();
            clearData();
            alert("Data Added Successfully");
     }

     function clearData() {
            document.getElementById('id_number').value = "";
            document.getElementById('first_name').value = "";
                     }
    </script>

And right now I have it onClick="javascript:addToCSVFile()">, but it also doesn’t work when I set the form action to the handler.php and mothod file to publish and remove onlick. This is a php file.

   <?
    if(isset($_POST['match_scouting'])){
       $del = "\t";
     //Collect Info
     $data[1] = $_POST['id_number'];
     $data[2] = $_POST['first_name'];
    $file = fopen("Data.csv", "a");
    $data = "\r\n".implode($del, $data);
    fwrite($file, $data);
    fclose($file);
    echo "The data has been added successfully";
 }else{
   header("location: form.html");
 }
 ?>

javascript.

<form name="xyz_form" action="proces.php" method="get">

submit php. php :

<?php
    $keys = array('id_number','first_name');
    $csv_line = array();
    foreach($keys as $key){
        array_push($csv_line,'' . $_GET[$key]);
    }
    $fname = 'file_to_write_to.csv';
    $csv_line = implode(',',$csv_line);
    if(!file_exists($fname)){$csv_line = "\r\n" . $csv_line;}
    $fcon = fopen($fname,'a');
    $fcontent = $csv_line;
    fwrite($fcon,$csv_line);
    fclose($fcon);
?>

$Keys - , , , . $fname - , . csv .

: php. . , : PHP?. :

echo file_get_contents($fname);
