php track window close!!!

mshen

Javescript can control window close like this.

<HTML>
<HEAD>
<TITLE>onBeforeUnload Event Handler</TITLE>

<SCRIPT LANGUAGE="JavaScript">
function verifyClose() {
event.returnValue = "We really like you and hope you will stay longer."
}
window.onbeforeunload = verifyClose
</SCRIPT>
</HEAD>
<BODY>
<H1>onBeforeUnload Event Handler</H1>
<HR>
<P>Use this button to navigate to the previous page:
<BUTTON ID="go" onClick="history.back()">
Go Back
</BUTTON>
</BODY>
</HTML>

but the problem is that php how to know the window already close or not. and save a value (0 or 1)to MySQL datebase.

Thanks.

I've never used it but connection_aborted() may be your answer.

it returns true if the window is closed. and by using ignore_user_abort(true); first, you will beable to run the rest of the script
