    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.
