fsockopen - bind to IP?

[MrManager]

Is there a way to tell fsockopen() to bind to a certain IP?

Not that I know of. I'm not sure, but I think the kernel always chooses the source IP for an outbound connection based on the routing table.

If you mean bind to a specific IP to accept inbound connections, then yes PHP can, but that's not fsockopen().

Any idea how I could do that, then? Is there an alternate function that allows for something like this?
