C++和PHP套接字连接

我想使用PHP ... 到目前为止连接到我的C++服务器，我得到：C++和PHP套接字连接

Server.cpp

#include <winsock2.h> 
#include <iostream> 
using namespace std; 

int main(int argc, char *argv[]) 
{ 
WSADATA wsaData; 
SOCKET mySocket; 
SOCKET myBackup; 
SOCKET acceptSocket; 
sockaddr_in myAddress; 


// setup WSA and socket....  
if(WSAStartup(MAKEWORD(2, 2), &wsaData) != NO_ERROR) 
    { 
    cerr<<"Socket Initialization: Error with WSAStartup\n"; 
    system("pause"); 
    WSACleanup(); 
    exit(10); 
} 

//Create a socket 
mySocket = socket(AF_INET, SOCK_STREAM, IPPROTO_TCP); 

if (mySocket == INVALID_SOCKET) 
{ 
    cerr<<"Socket Initialization: Error creating socket"<<endl; 
    system("pause"); 
    WSACleanup(); 
    exit(11); 
} 

myBackup = mySocket; 


//bind 
myAddress.sin_family = AF_INET; 
myAddress.sin_addr.s_addr = inet_addr("0.0.0.0"); 
myAddress.sin_port = htons(25555); 


if (bind (mySocket, (SOCKADDR*) &myAddress, sizeof(myAddress)) == SOCKET_ERROR) 
{ 
    cerr<<"ServerSocket: Failed to connect\n"; 
    system("pause"); 
    WSACleanup(); 
    exit(14); 
} 

//listen 
if (listen (mySocket, 10) == SOCKET_ERROR) 
{ 
    cout<<"ERR: ServerSocket: Error listening on socket\n"; 
    system("pause"); 
    WSACleanup(); 
    exit(15); 
} 
cout<<"srv started. listeninig...\n"; 

//accept 
acceptSocket = accept(myBackup, NULL, NULL); 
while (acceptSocket == SOCKET_ERROR) 
{ 
    acceptSocket = accept(myBackup, NULL, NULL); 
} 
mySocket = acceptSocket; 

cout<<"done.\n"; 

return 0; 
}

和PHP客户端

<?php 
$port = 25555; 
$socket = socket_create(AF_INET,SOCK_STREAM,SOL_TCP); 
#socket_bind($socket,'',$port); 
socket_connect($socket, '/my_ip/', $port); 

echo 'connecting...'; 
?>

我不知道该怎么做。 C++服务器只是不能看到PHP客户端...

您已经验证您的服务器接受来自任何东西连接？ 'telnet your.ip.add.ress 25555' –

或者做一个'netstat -plt' –

你需要在PHP中正确的检查，以确保一切正常。

试试这个：

$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP); 
    if ($socket === false) { 
     die("socket_create() failed: Reason: " . socket_strerror(socket_last_error()) . "\n\n"); 
     return false; 
    } 

    echo("Attempting to connect to '{$IP}' on port '{$PORT}'"); 
    $result = socket_connect($socket, $IP, $PORT); 
    if ($result === false) { 
     echo("socket_connect() failed. Reason: ($result) " . socket_strerror(socket_last_error($socket)) . "\n\n"); 
     return false; 
    } else { 
     echo "OK.\n\n"; 
    }

Thanx快速回复。我试过尼尔的代码，我得到了：尝试连接'83 .24.47.45'端口'25555'OK。即使服务器关闭或不在... –

@ user1023753确保该端口不是某个共享或开放端口 – Neal

检查错误代码......

socket_create 

socket_create() returns a socket resource on success, or FALSE on error.

和

socket_connect 

Returns TRUE on success or FALSE on failure. 
The error code can be retrieved with socket_last_error(). 
This code may be passed to socket_strerror() to get a textual explanation of the error.
