Notice !

if you running a loop (while, foeach etc..) you have to send something to the browser to check the status.

Example:

while(1){
if (connection_status()!=0){
die;
}
}
doesnt work, if the user break/close the browser.

But a:

while(1){
Echo "\n"; //<-- send this to the client
if (connection_status()!=0){
die;
}
}
will work :)

i hope it will help some of you to safe some time :)

As mentioned, this function returns a status bitfield to which there's a set of constants available. I don't know why those constants aren't actually listed. Although they're easy to guess, I think it's still worth listing them, it is documentation after all. This function has the ability to return integers 0 through 3 so there are 4 possible states.

The constants are as follows:

CONNECTION_NORMAL = 0
CONNECTION_ABORTED = 1
CONNECTION_TIMEOUT = 2

As a 4th state is possible and being a bitfield, this gives rise to CONNECTION_ABORTED|CONNECTION_TIMEOUT (or integer 3) can be used to check for aborted+timeout states.
