Manual
socket_set_nonblock(
Socket$socket ): bool
The socket_set_nonblock function sets the O_NONBLOCK flag on the socket specified by the socket parameter.
When an operation (e.g. receive, send, connect, accept, ...) is performed on a non-blocking socket, the script will not pause its execution until it receives a signal or it can perform the operation. Rather, if the operation would result in a block, the called function will fail.
Parameters

-
A Socket instance created with socket_create or socket_accept.
