php与C语言通过AF_UNIX来进行IPC通信的例子
php与C语言通过AF_UNIX来进行IPC通信的例子
1）编写s_unix.c服务端文件
#include <stdio.h>#include <sys/types.h>#include <sys/socket.h>#include <sys/un.h> #define UNIX_DOMAIN "/tmp/UNIX.domain"int main(void){ socklen_t clt_addr_len; int listen_fd; int com_fd; int ret; int i; static char recv_buf[1024]; int len; struct sockaddr_un clt_addr; struct sockaddr_un srv_addr; listen_fd=socket(PF_UNIX,SOCK_STREAM,0); if(listen_fd<0) { perror("cannot create communication socket"); return 1; } //set server addr_param srv_addr.sun_family=AF_UNIX; strncpy(srv_addr.sun_path,UNIX_DOMAIN,sizeof(srv_addr.sun_path)-1); unlink(UNIX_DOMAIN); //bind sockfd & addr ret=bind(listen_fd,(struct sockaddr*)&srv_addr,sizeof(srv_addr)); if(ret==-1) { perror("cannot bind server socket"); close(listen_fd); unlink(UNIX_DOMAIN); return 1; } //listen sockfd ret=listen(listen_fd,1); if(ret==-1) { perror("cannot listen the client connect request"); close(listen_fd); unlink(UNIX_DOMAIN); return 1; } //have connect request use accept len=sizeof(clt_addr); com_fd=accept(listen_fd,(struct sockaddr*)&clt_addr,&len); if(com_fd<0) { perror("cannot accept client connect request"); close(listen_fd); unlink(UNIX_DOMAIN); return 1; } //read and printf sent client info printf("/n=====info=====/n"); for(i=0;i<4;i++) { memset(recv_buf,0,1024); int num=read(com_fd,recv_buf,sizeof(recv_buf));//printf("num=%d/n",num); printf("Message from client (%d)) :%s/n",num,recv_buf);//printf("i=%d/n",i);write(com_fd,"hello world",11,0);printf("/n%s/n","server to client msg ok"); } // write(com_fd,"hello world",11,0); // printf("/n%s/n","server to client msg ok");//printf("%s/n","end"); //write(listen_fd,"aaadfd",6,0); close(com_fd); close(listen_fd); unlink(UNIX_DOMAIN); return 0;}?2）编写c_unix.c客户端文件
#include <stdio.h>#include <sys/types.h>#include <sys/socket.h>#include <sys/un.h>#define UNIX_DOMAIN "/tmp/UNIX.domain"int main(void){ int connect_fd; int ret; char snd_buf[1024]; int i; static struct sockaddr_un srv_addr;//creat unix socket connect_fd=socket(PF_UNIX,SOCK_STREAM,0); if(connect_fd<0) { perror("cannot create communication socket"); return 1; } srv_addr.sun_family=AF_UNIX; strcpy(srv_addr.sun_path,UNIX_DOMAIN);//connect server ret=connect(connect_fd,(struct sockaddr*)&srv_addr,sizeof(srv_addr)); if(ret==-1) { perror("cannot connect to the server"); close(connect_fd); return 1; } memset(snd_buf,0,1024); strcpy(snd_buf,"message from client");//send info server for(i=0;i<4;i++) write(connect_fd,snd_buf,sizeof(snd_buf)); close(connect_fd); return 0;}?3）编写PHP客户端文件 test.php
<?php define("UNIX_DOMAIN","/tmp/UNIX.domain");// echo UNIX_DOMAIN; $socket = socket_create(AF_UNIX, SOCK_STREAM, 0); //第三个参数为0 if ($socket < 0) { echo "socket_create() failed: reason: " . socket_strerror($socket) . "\n"; } else { echo "create OK.\n"; } $result = socket_connect($socket, UNIX_DOMAIN); //这里只要两个参数即可 if ($result < 0) { echo "socket_connect() failed.\nReason: ($result) " . socket_strerror($result) . "\n"; } else { echo "connect OK"; } //下面的代码和普通php socket通信一致 $in = "测试IPC通信\n"; if(!socket_write($socket, $in, strlen($in))) { echo "socket_write() failed: reason: " . socket_strerror($socket) . "\n"; } else { echo "send message ok！\n"; echo "\naccept message=".socket_read($socket, 8192)."\n"; } echo "Close SOCKET...\n"; socket_close($socket); echo "Close OK\n"; ?>?4）编译s_unix.c和c_unix.c文件
gcc s_unix.c -o s_unix
gcc c_unix.c -o c_unix
5）运行测试
先启动一个窗口运行s_unix，方法 为：./s_unix
然后 再开启一个窗口运行c_unix进行测试 ：./c_unix
这里主要是来测试 PHP与C语言的通信? 可以再开启一个窗口运行php test.php即可
效果如图 ：
