Need help with cookies

CSV

So I know that both php and javascript work with cookies and you can create a cookie in php and use that one in javascript.

now I have this code

// csv code werkt wel tot ik de set cookie gebruik om
      $csv_file = "filename.csv";

      // Open the file for reading
      $file_handle = fopen($csv_file, "r");

      // Read the contents of the file
      while (($row_data = fgetcsv($file_handle, 1000, ';')) !== FALSE) {
          if (empty($Toevoeging)){
            if ($row_data[0] == $Zipcode && $row_data[1] == $Housenumber ) {
              // User input found in the CSV
              // $_SESSION['input_found'] = "user input found";
              // echo $_SESSION['input_found'];
              $user_input = "User Input Found";
              setcookie("user_input", $user_input);
              break 1;
             }
          }else{

            if ($row_data[0] == $Zipcode && $row_data[1] == $Housenumber && $row_data[2] == $Toevoeging) {
              // User input found in the CSV
              // $user_input = "";
                $user_input = " Found";
                setcookie("user_input", $user_input);
                break 1;
              }else{
                $user_input = "User Input NOT Found";
                setcookie("user_input", $user_input);
                break 1;
              }
          }

      }
      // Close the file handle
      fclose($file_handle);

and I know that it works because I used it without cookies and just hard coded it in there for testing perposes (not good at reading csvs) however it's not working anymore. when I show the var in my table
javascript:

var obj = JSON.parse(msg);
            var match = document.cookie.match(new RegExp('user_input=([^;]+)'));

            var input = decodeURIComponent(match[1]);

             // var noSpecialChars = input.replace(/[^A-Za-z]+/g, '');
             var table = $('#displayTable');
             //reset de table zodat er nieuwe td in kan komen.
         $('#displayTable > td').remove();

             for (var i = 0; i < Object.keys(obj[0].AvailableSupplier.AvailableSpeeds.AvailableSpeed).length; i++) {
                 //tabel append is row toevoegen aan table
                 table.append("<tr>");
                 table.append("<td>" + input + "</td>");
                 table.append("<td>" + obj[0].AvailableSupplier.AvailableSpeeds.AvailableSpeed[i].Technology + "</td>");
                 table.append("<td>" + obj[0].AvailableSupplier.AvailableSpeeds.AvailableSpeed[i].Availability + "</td>");
                 table.append("<td>" + obj[0].AvailableSupplier.AvailableSpeeds.AvailableSpeed[i].Description + "</td>");
                 table.append("</tr>");

             }

it only shows me user input found.
but this is wrong.
the csv check is supposed to check if the entered zipcode and housenumber is in the csv. if they are the user input is found
if the zipcode housenumber and extra letter (don't know the english word sorry example would be: zipcode: 7492 SI Housenumber:34A).

and if they arent in there the user input is not found. this code used to work when I just said echo "user input found" and so on.
how do I fix this

What I have tried:

checkt the internet about cookies. but don't really know what to look up because this is supposed to work.
