In PHP, how to destroy session and close the window?

Question

I want to close the tab as well as destroy the sessions in the php.

I have this piece of code, but doesn't work well.

<?php
session_start();
session_destroy();
?>

<script language="javascript"> 

setTimeout("self.close();",10000) 

</script>

Help through, Thanks.

Edit: It doesn't close the window as expected.

Answer 1

function openWin()
{
myWindow=window.open("","","width=200,height=100");
myWindow.document.write("<p>This is 'myWindow'</p>");
}

function closeWin()
{
myWindow.close();
}

Hope you have tried to use firefox browser to test

In firefox, You can only close window via JavaScript that have been open via a script window.open() call.

Please refer the below link

Try Internet explorer.
