Php interaction with other languages (80) Suppose I have a web server S1 and an application server S2 (such as the search function) S1y written in php, s2 applications are written in c (or java, c ++). how can I implement the interaction process between the two servers? 1. user access S1 & nbsp; 2. the server submits the operation to S23.S2 and returns the operation result to S1 & nbsp; 4. s1 return information to the user ------ solve the interaction between php and other languages (80)
Assume that I have a web server S1
There is also an application server S2 (such as the search function)
S1y is written in php, and S2 applications are written in c (or java, c ++,
How to implement interaction between the two servers
The process is like this,
1. user access S1
2. the server submits the operation to S2.
3. S2 returns the operation result to S1
4. S1 returns information to the user

Soap

Is json not acceptable?
------ Solution --------------------
Any data communication solution between servers on the network can be used.
Soap/xmlrpc/REST/json (p )/
If you have sufficient control permissions on both servers,
Of course, you can also directly communicate through the socket (non-Port 80 can be used)
If both servers can operate on a public media, such as the same database or network file system,
Of course, you can also transmit data through this media...

JSON (JavaScript Object Notation) is a lightweight data exchange format. It is based on a subset of JavaScript (Standard ECMA-262 3rd Edition-December 1999. JSON uses a completely language-independent text format, but it also uses a habit similar to the C language family (including C, C ++, C #, Java, JavaScript, Perl, Python, and so on ). These features make JSON an ideal data exchange language. Easy for reading and writing, and easy for machine parsing and generation.

Of course there is a slight difference. The goal is the same.

The simplest method is to use file_get_contents ('http: // ip: Port') of php, and pass the value through GET or POST, the return value of a function is the processing result of S2. The key is how S2 creates an http-based listener.
You can use libevent to quickly create an http service. a simple code is as follows:
C/C ++ code
#include < sys/types.h> #include < stdio.h> #include < stdlib.h> #include < unistd.h> #include < event.h> #include < evhttp.h> void generic_request_handler(struct evhttp_request *req, void *arg) { struct evbuffer *returnbuffer = evbuffer_new(); evbuffer_add_printf(returnbuffer, "Thanks for the request!"); evhttp_send_reply(req, HTTP_OK, "Client", returnbuffer); evbuffer_free(returnbuffer); return; } int main(int argc, char **argv) { short http_port = 8084; char *http_addr = "0.0.0.0"; struct evhttp *http_server = NULL; event_init(); http_server = evhttp_start(http_addr, http_port); evhttp_set_gencb(http_server, generic_request_handler, NULL); fprintf(stderr, "Server started on port %d\n", http_port); event_dispatch(); return(0); }
