【问题描述】:
我是套接字编程的新手。我有一个 GPS 跟踪器,它通过 GPRS 连接连接并将数据发送到定义的公共服务器:端口。 我在终端上得到结果。
我想知道如何在某个变量中获得该响应,以便将这些条目实时保存在数据库中。
这里是代码。
require_once("SocketServer.class.php"); // Include the File
$server = new SocketServer("xxx.xx.x.xxx",8153); // Create a Server binding to the given ip address and listen to port 31337 for connections
$server->max_clients = 10; // Allow no more than 10 people to connect at a time
$server->hook("CONNECT","handle_connect"); // Run handle_connect every time someone connects
$server->hook("INPUT","handle_input"); // Run handle_input whenever text is sent to the server
$server->infinite_loop(); // Run Server Code Until Process is terminated.
function handle_connect(&$server,&$client,$input)
{
SocketServer::socket_write_smart($client->socket,"String? ","");
}
function handle_input(&$server,&$client,$input)
{
// You probably want to sanitize your inputs here
$trim = trim($input); // Trim the input, Remove Line Endings and Extra Whitespace.
if(strtolower($trim) == "quit") // User Wants to quit the server
{
SocketServer::socket_write_smart($client->socket,"Oh... Goodbye..."); // Give the user a sad goodbye message, meany!
$server->disconnect($client->server_clients_index); // Disconnect this client.
return; // Ends the function
}
$output = strrev($trim); // Reverse the String
echo "output is".$trim;
SocketServer::socket_write_smart($client->socket,$output); // Send the Client back the String
SocketServer::socket_write_smart($client->socket,"String? ",""); // Request Another String
}
SocketServer.class.php
http://www.phpclasses.org/browse/file/31975.html
此行不会在终端上打印结果
echo "output is".$trim;
我也试过了
$myfile = fopen("file.txt", "w") or die("Unable to open file!");
fwrite($myfile, $trim);
fclose($myfile);
文件保持为空
【问题讨论】:
-
你的意思是它已经是
$trim是一个变量,并且内容在一个变量中。所以在$trim之后将其保存在您的数据库中。在函数之前打开文件顶部的数据库连接,并在函数中使用它,使用global $dbConnection;然后$dbConnection->prepair()/$dbConnection->query() -
我知道如何处理数据库。但是当我这样做时 echo "output is".$trim;它不显示“输出是”,然后是结果
-
你知道这个包已经很老了,现在可以使用不是吗?
7 years ago你最好使用支持 Async 的库,就像 PHP 7 一样,https://github.com/dazzle-php/socket
