我想实现一些看似荒谬的事情。
我已经创建了一个创建服务器套接字的PHP脚本。我能够从java客户端连接到服务器套接字。
现在我想要的是在服务器端的某个地方维护这个套接字，以便以后需要时可以访问它。
但是，这里的问题是，一旦responsd（）函数终止，套接字就会关闭，Run类中的br.readLine（）方法就会收到空行。
出于我的目的，readLine（）方法应该继续等待响应。
到目前为止我所做的。。。
regsock.php（在应该注册套接字的地方）
<?php
set_time_limit(0);
$fh = fopen("reg.txt", "w");
fwrite($fh, "SERVER Starting'r'n");
$sersock = socket_create_listen(1234);
fwrite($fh, "SERVER Running'r'n");
while(true){
respond();
}
function respond(){
global $sersock, $fh;
$sock = socket_accept($sersock);
fwrite($fh, "Client Connected'r'n");
echo "Client: ".socket_read($sock, 1024);
socket_write($sock, "OK'n'r");
//Some way to store client sockets?
}
socket_close($sersock);
fclose($fh);
?>
Run.java
Socket socket = new Socket("localhost", 1234);
BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(
socket.getOutputStream()));
BufferedReader br = new BufferedReader(new InputStreamReader(
socket.getInputStream()));
bw.write("Server OK?");
bw.flush();
System.out.println("Server:"+br.readLine()); //Output-> Server:OK
System.out.println("Server:"+br.readLine()); //Output-> Server:
bw.close();
br.close();
socket.close();
而且，remote.php（我想访问resgsock.php上接受的套接字的位置）
<?php
$sock = //Retrieve socket resource here
fwrite($sock, "REMOTE PAGE'r'n");
echo "Socket write complete";
?>
这可能吗？或者我只是做错了一切。
这可以通过其他方法来实现吗。
regsock.php中接受的套接字只能在remote.php与regsock在同一进程或子进程中执行时传递给remote.php。
例如，你可以这样做：
# In global setup: handle child process termination automatically
# Might break calls to "system" though
pcntl_signal(SIGCHLD, SIG_IGN);
function respond(){
global $sersock, $fh;
$sock = socket_accept($sersock);
fwrite($fh, "Client Connected'r'n");
echo "Client: ".socket_read($sock, 1024);
socket_write($sock, "OK'n'r");
$pid = pcntl_fork();
if ($pid == 0) {
# This is now a subprocess. If I "include" remote.php
# it can operate on $sock as if it was its own.
include "remote.php";
# Now exit the subprocess
exit;
} elsif ($pid < 0) {
# fork failed, handle error
} else {
echo "Subprocess running with pid $pid!";
# Close the copy of the socket in parent process,
# subprocess has a copy of its own.
socket_close($sock);
}
}
