[Vinod Bahadur Thapa]

<?php

   $server = "localhost";
    $user ="root";
    $password="";
    $db="pdophp";

    $dbcon = new PDO("mysql:host=$server; dbname=$db", $user, $password );

try{

$dbcon->exec("insert into studentstable(name,age,class,gender) values('vinodth',26,11,'male')");

echo 'inserted successful';
}catch(PDOException $e)
    {
    echo $sql . "<br>" . $e->getMessage();
    }
?>

Code is working. Values are inserting but Twice into the Table. I tried but where I am doing wrong. Could you help plz.

Is that your whole code? Because nothing in that code will cause to insert twice.

yes,  I don't know why it is happening. When I try the same code on Microsoft edge it's work.

I could be miss understanding but your asking why is there more then one row in the database or that when you refresh the page it inserts two records at once?

 

Everytime you run the browser / load this up it will insert a new row into the database. Maybe you want a constraint in the database to not have a row with the same name and age?
