and code when try insert change php script on top:

<?php     include 'db.php';     $stmt = $db->prepare('select * ' . $table);     $stmt->execute();      if(isset($_post['btn-insert'])){          $prodname = $_post['prod_name'];         $prodsupp = $_post['prod_supplier'];         $prodprice = $_post['prod_price'];          $db = new pdo('mysql:host' . $host . ';dbname=' . $dbname, $dbusername, $dbpassword);         $db->setattribute(pdo::attr_errmode, pdo::errmode_exception);         $stmt = $db->prepare("insert tbl_product(prod_name, prod_supplier, prod_price) values('$prodname', '$prodsupp', '$prodprice')");      } ?>

this happens: enter image description here

thats problem have encountered right @ moment.

you created conflict in "stmt" variable... firstly 

  $stmt = $db->prepare('select * ' . $table);   $stmt->execute();

then:

 $stmt = $db->prepare("insert into...

so since prepared insert statement,

this not fetching anything.. check conflict , fine..

  $product = $stmt->fetch(pdo::fetch_obj)

(side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now...
