Bug description: faster client lookup after socket_select
Description:
------------
it's slow that phpscript itself have to loop through $fds and use in_array
to know which client is sending data
$allfds[0] = socket_create(...);
$clients[0] = new MyClient($allfds[0]);
...
$count = socket_select($fds);
for ($i = 0; $i < FDSIZE; $i ++) {
if (in_array($fds, $allfds[$i])) {
$clients[$i]->processIncomingData();
}
}
larger FDSIZE make script slower
i'd suggest $fd resource store more information: ID
int socket_set_id(source $sock)
int socket_get_id(source $sock)
$allfds[0] = socket_create(...);
$clients[0] = new MyClient($allfds[0]);
socket_set_id($allfds[0], 0);
$allfds[1] = socket_create(...);
$clients[1] = new MyClient($allfds[1]);
socket_set_id($allfds[1], 1);
$count = socket_select($fds);
for ($i = 0; $i < $count; $i ++) {
$id = socket_get_id($fds[$i]);
$clients[$id]->processIncomingData();
}
speed is not depend on FDSIZE
