socket_connect does not timeout

Question

I am using sockets to send data to a server that may not be responding. So I am trying to define a timeout by using this solution in SO.

Make PHP socket_connect time

Answer 1

I changed my socket communication mechanism to use stream_socket_client ($remote_socket, &$errno, &$errstr, $timeout) function instead. This function allows to define the connect timeout unlike socket_connect ($socket, $address, $port) which doesn't.

To force a timeout using socket_connect see @bigtallbill answer.
