?php

//接收數(shù)據(jù)-處理數(shù)據(jù)-返回數(shù)據(jù)

echo?json_encode($_POST);

php怎么提交數(shù)據(jù)到另一個網(wǎng)站，然后要他返回一個值

這個可以通過PHP的curl請求來提交數(shù)據(jù)到其他的網(wǎng)站！獲取執(zhí)行的結(jié)果即可！以下是一個示例。

function?curlpost($data,$url){????????????????????//curlpost提交函數(shù)

$data=array('data'=$data);

$ch?=?curl_init?();

curl_setopt?($ch,?CURLOPT_URL,?$url?);

curl_setopt?($ch,?CURLOPT_POST,?true?);

curl_setopt?($ch,?CURLOPT_HEADER,?0?);

curl_setopt?($ch,?CURLOPT_RETURNTRANSFER,?1?);

curl_setopt?($ch,?CURLOPT_POSTFIELDS,?$data?);

$state=curl_exec?($ch?);

curl_close?($ch?);

return?$state;

}

PHP怎么與C語言通信？

/*server.c*/

#include string.h

#include stdio.h

#include netinet/in.h

#include stdlib.h

#define SERV_PORT 8000

int main()

{

int sockfd,n,servaddr_len,client_len,connfd;

char * server_ip = "127.0.0.1";

char buf[80];

struct sockaddr_in server,client;

sockfd = socket (AF_INET,SOCK_STREAM,0);

bzero(server,sizeof(server));

server.sin_family = AF_INET;

server.sin_addr.s_addr = inet_addr(server_ip);

server.sin_port = htons(SERV_PORT);

servaddr_len = sizeof(server);

client_len=sizeof(client);

bind(sockfd,(struct sockaddr *) server,servaddr_len);

listen(sockfd,6);

while(1)

{

bzero(buf,sizeof(buf));

printf("等待讀取數(shù)據(jù).......\n");

connfd=accept(sockfd,(struct sockaddr *)client,client_len);

n = read(connfd,buf,sizeof(buf));

write(connfd,buf,n);

printf("讀取的數(shù)據(jù)為:%s\n",buf);

}

close(sockfd);

return 0;

}

?php

$server_ip="127.0.0.1";

$port = 8000;

if($_POST['submit'])

{

$buf=trim($_POST['buf']);

$sockfd=socket_create(AF_INET,SOCK_STREAM,SOL_TCP)or die("創(chuàng)建失敗");

socket_connect($sockfd,$server_ip,$port)or die("連接錯誤");

socket_write($sockfd,$buf,strlen($buf))or die("寫入錯誤");

$a=socket_read($sockfd,80);

echo $a;

$buf="";

socket_close($sockfd);

}

?

form action="tcpclient.php" method="post"

請選則發(fā)送方式：brinput type=text name="buf"

input type=submit name="submit" value="發(fā)送"

/form

tcp方式不能通信解決方法

執(zhí)行：getsebool -a |grep http

查看httpd_can_network_connect -- off 是否為打開狀態(tài)

執(zhí)行：setsebool httpd_can_network_connect on 把httpd_can_network_connect設(shè)置為打開狀態(tài)
