沟通的C程序和PHP [英] communicate c program and php

问题描述

我想有一个网页（用PHP编写的，因为这是我知道的），显示的输入值。我想这个值要传递给正在运行的是C programa。

I want to have a web page (written in php because it's what i know) that displays an input value. I want that value to be passed to a c programa that's already running.

我使用套接字两种工艺之间进行通信的，虽然，但我怎么能做到呢？我该如何使用的fsockopen连接到本地套接字。

I though of using sockets to communicate between both process, but how do I manage to do that? how can I use fsockopen to connect to a local socket.

推荐答案

一些简单的解决方案，我能想到的是：

Some simple solutions I can think of are:

您可以使用 Redis的作为使用的 hiredis 作为C客户端库。我从来没有使用hiredis库之前，但这样做只是现在您测试和库真的很好。我能知道它，因为Redis是C code的最好的一块，我知道。）

You could use redis as your ipc using hiredis as your c client library. I never used hiredis library before but did it just now for you to test and the library is really good. I could have known it because redis is the best piece of C code I know :).

修改example.c

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include "hiredis.h"

int main(void) {
    redisContext *c;
    redisReply *reply;

    c = redisConnect((char*)"127.0.0.1", 6379);
    if (c->err) {
        printf("Connection error: %s\n", c->errstr);
        redisFree(c);
        exit(1);
    }

    /* Blocking pop. */
    reply = redisCommand(c, "BLPOP php 0");
    if (reply->type == REDIS_REPLY_ARRAY) {
        if (reply->elements == 2) {
            printf("%s\n", reply->element[1]->str);
        }
    }
    freeReplyObject(reply);
    redisFree(c);
    return 0;
}

编译并运行例如：

make
./hiredis-example

从./redis-cli：

这是另一个选项卡开始启动Redis的-CLI（原型），并发出以下命令。你应该preDIS作为PHP客户端库替换此，但将是非常容易的：

from another tab start start redis-cli(for prototyping) and issue the following command. You should replace this with predis as php client library, but that is going to be very easy:

lpush php "Hello from PHP"

内部运行hiredis，例如：

您应该看到消息Hello从PHP。易如反掌，如果你问我：）

You should see the message "Hello from PHP". Easy as pie if you ask me :).

您可以使用命名管道的。

您可以阅读 Beej的指南网络编程使用Internet套接字。在我看来这是一个非常良好的阅读。

You could read the Beej's Guide to Network Programming Using Internet Sockets. In my opinion this is a very good read.
