How do I detect a disconnected client from a socket resource?
In an infinite loop, I socket_read() every open resource that passes a socket_select().
As far as I know, the only way to detect if the client disconnected unexpectedly from their socket resource is when socket_read() returns FALSE (which, during my testing, produced the warning: "An established connection was aborted by the software in your host machine.").
However, socket_read() doesn't return FALSE on a disconnected client's socket resource until I first attempt to socket_write() to that resource.
In brief pseudo code...
socket_create(AF_INET, SOCK_STREAM, SOL_TCP)
while (TRUE)
foreach (resource where (false === socket_select($arrayofresources, NULL, NULL, 0, 0))
if (socket_read() === false)
WON'T DETECT DISCONNECT UNTIL I FIRST socket_write()
I appreciate any support you offer and thank you for your time.
Best regards,
-Tony
