How do I run a meta tag using php?
if (mail("m@me.com",$subject,$ipmessage,$header) ==1){
    echo "Thank You Your Message Has Been Sent!";
    <meta http-equiv="refresh" content="3;url=index.php">
}

if (mail("m@me.com",$subject,$ipmessage,$header)){
    echo "Thank You Your Message Has Been Sent!";
  ?>
    <meta http-equiv="refresh" content="3;url=index.php">
 <?php
  }
?>

if (mail("m@me.com",$subject,$ipmessage,$header)){
    echo "Thank You Your Message Has Been Sent!";
    header("Refresh: 3;index.php");
  }

<?php
ob_start();

if (mail("m@me.com",$subject,$ipmessage,$header)){

    echo "Thank You Your Message Has Been Sent! ";
    header("Refresh: 10; url=index.php"); //You will be redirect in 10 seconds
  }


ob_flush();
?>
