Stream_socket_xxxx and socket_xxx Differences in PHP

Read the manual, not too clear stream_socket_xxxx and socket_xxx have what connection

For example: Stream_socket_recvfrom and Socket_recvfrom are functionally the same except for different parameters

Is it possible to understand that one is another extension?

For example: Stream_socket_client and socket_create seem to be able to create socket resources, and the stream is a bit more powerful

Younger brother White hand, do not understand just want to ask.

PS: Suddenly see a fsocketopen, how the socket variant so many?

Stream_socket_xxxx is the encapsulation of some functions, such as sockets.

It is recommended to use the stream_* function anyway
