Bug description:connection_status(), connection_aborted() not working

Description:
------------
connection_status(), connection_aborted () never detect closed remote
connection.

After closing connection initiated from client (e.g. wget) connection
state becomes CLOSE_WAIT from ESTABLISHED, but those two functions
called in a loop never detect that, even when outputing data.

Current solution is to popen netstat, or parse /proc/net/tcp,
/proc/net/tcp6 to find if connection is established.

connection_status/connection_aborted should detect the connection loss
even without writing anything. Currently those functions do nothing.

Test script:
---------------
<?php
ignore_user_abort(false);
function fecho($str) {
    file_put_contents("conlog.txt",$str."",FILE_APPEND);
}
while (1) {
    sleep (1);
    $d=date(DATE_RFC2822);
    $remport=$_SERVER['REMOTE_PORT'];
    $remip =
$_SERVER['REMOTE_ADDR']?:($_SERVER['HTTP_X_FORWARDED_FOR']?:$_SERVER['HTTP_CLIENT_IP']);
   
file_put_contents("conlog.txt","date:$d\tip:$remip\tport:$remport\tstatus:$constatus\n",FILE_APPEND);
    echo "...\n"; 
    flush();
    if (connection_status()!= CONNECTION_NORMAL){ //never works
        file_put_contents("conlog.txt","connection
closed\n",FILE_APPEND);
        break;
    }
   
file_put_contents("conlog.txt","connection_status=".connection_status().
        "
connection_aborted():".connection_aborted()."\n",FILE_APPEND);
}
?>


Expected result:
----------------
The above writes on a file named conlog.txt. Call the above script with
wget. The script should start writing data to conlog.txt at the server.
Then press Ctrl+C to stop wget. The script should end. 



Actual result:
--------------
The script never stops running.
