There could be a more sophisticated way to check this but a simple way would be to set some session variables in the receiving module equal to your post variables (first time thru). On each call you check the session variables against the $_POST variables and if they are the same, you take no action and optionally issue a warning message.

Can you help me on my script if possible please. thank you very much

While it's not a terribly elegant solution, I've had a lot of luck with this method.

call it testpost.php

<?php
if (isset($_POST['submit1']))
 {
 $var1=$_POST['var1'];
 $var2=$_POST['var2'];
 echo "Your information has been posted.";
 echo "<script>setTimeout(\"location.replace('testpost.php')\",2000)</script>";
 }
?>

<form action="testpost.php" method="post">
<input type="text" name="var1" /><br />
<input type="text" name="var2" /><br />
<input type="submit" name="submit1" value="SUBMIT" />
</form>

The reason I like this so well is that 1) You can have multiple forms and multiple submit buttons on one page, 2) You're using the same page to submit as you're using for the form, 3) Using the 2 second timeout allows you to let the user know the info has been posted, and 4) After 2 seconds the page reloads with no $_POST variables so if you refresh manually it won't post again.

I don't remember if I got the single/double and escaped quotes right, you'll have to test that for yourself.
