Connection Handeling Doesn't Work in PHP

[hadji_85]

I have read every single thing on connection handeling with no luck. What I want to do is simple.

I want a user to be able to go to a website where when he loses connection to the site (because maybe wifi cut off) a timestamp is written to a file.

So the flow would be this.

1. user goes to www.testinternet.com
2. user leaves his browser there
3. when the user's internet disconnects, I write the time it disconnected to a file.

Everything I have tried doesn't seem to detect the disconnect.

Inside in PHP a connection status is preserved. There are 3 probable states:
0 - NORMAL
1 - ABORTED
2 - TIMEOUT

While a PHP script is running usually the NORMAL state, is active. If the remote client disconnects the ABORTED state flag is switched on. A remote client disconnect is generally caused by the user hitting his STOP key. If the PHP-imposed time limit is hit, the TIMEOUT state flag is switched on.
