I want to display this alert box on the same page. It get redirect to blank page then shows alert box . If goback() removed then it redirects to blank page and does no return back to previous page.
how to solve this?

You are missing something. How it can be possible to display a popup related to another page without sending any request to it? First I have set a success session in mail.php page which is set if mail is sent successfully.
<?php
session_start();
function goback()
{
$_SESSION['success'] = 'true';
header("location:index.php");
}
if(isset($_POST['submit'])){
$name = $_POST['name'];
$comment = $_POST['comment'];
$mob = $_POST['mob'];
$email = $_POST['email'];
$to ='xyz#gmail.com';
$subject= 'Contact form pharma';
$message ="Name: ".$name."\n".
"Comment: ".$comment."\n".
"Mobile: ".$mob."\n".
"E-mail: ".$email;
if(mail($to, $subject, $message)){
goback();
}
else
{
echo "something went wrong";
}
}
?>
Then in index.php page we just have to call this session. if its true then we can show pupop
<?php
if(isset($_SESSION['success']) && $_SESSION['success']=='true')
{
//show pupop
$_SESSION['success'] = 'false';
}
?>
