$db_user="root";
$db_pass="";
$db_name="formend";
$db_table="jadval";
$con = mysql_connect($db_host,$db_user,$db_pass) or die("خطا در اتصال به پايگاه داده");
$selected=mysql_select_db($db_name, $con) or die("خطا در انتخاب پايگاه داده");
$dbresult=mysql_query("SELECT * FROM `jadval`");

    echo $amch["id"];
    echo $amch["name"];

Use mysqli_* instead as mysql_* has already been deprecated in PHP 5.5 and removed in PHP 7:

<?php
$db_host = "localhost";
$db_user = "root";
$db_pass = "";
$db_name = "formend";
$db_table = "jadval";
$con = mysqli_connect($db_host, $db_user, $db_pass, $db_name) or die("خطا در اتصال به پايگاه داده");

$dbresult = mysqli_query($con, "SELECT * FROM `jadval`");
while ($amch = mysqli_fetch_array($dbresult)) {
    echo $amch["id"];
    echo $amch["name"];
}
?>
