c++和PHP的套接字连接

C++ and PHP socket connection

本文关键字：套接字 连接 PHP c++      更新时间：2023-10-16

我想使用php连接到我的c++服务器…到目前为止，我得到了:

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 WSAStartupn";
    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 connectn";
    system("pause");
    WSACleanup();
    exit(14);
}
//listen
if ( listen ( mySocket, 10 ) == SOCKET_ERROR )
{
    cout<<"ERR: ServerSocket: Error listening on socketn";
    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...';
?>

我不知道该怎么办。

您需要在PHP中进行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()) . "nn");
        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)) . "nn");
        return false;
    } else {
        echo "OK.nn";
    }

检查错误码…

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.
