PHP - can't get to sockets to communicate
I'm using the following server.php (most of it is taken directly from PHP docs):
Code:
<?php
error_reporting(E_ALL);
set_time_limit(0);
ob_implicit_flush();
$address = '127.0.0.1';
$port = 10000;
$pass = "qazwsx";
if (($sock = socket_create(AF_INET, SOCK_STREAM, SOL_TCP)) === false) {
echo "socket_create() failed: reason: " . socket_strerror(socket_last_error()) . "\n";
}
if (socket_bind($sock, $address, $port) === false) {
echo "socket_bind() failed: reason: " . socket_strerror(socket_last_error($sock)) . "\n";
}
if (socket_listen($sock, 5) === false) {
echo "socket_listen() failed: reason: " . socket_strerror(socket_last_error($sock)) . "\n";
}
do {
if (($msgsock = socket_accept($sock)) === false) {
echo "socket_accept() failed: reason: " . socket_strerror(socket_last_error($sock)) . "\n";
break;
}
do {
if (false === ($buf = socket_read($msgsock, 2048, PHP_NORMAL_READ))) {
echo "socket_read() failed: reason: " . socket_strerror(socket_last_error($msgsock)) . "\n";
break 2;
}
if (!$buf = trim($buf)) {
continue;
}
if (preg_match("/^$pass/",$buf)) {
$cmd = substr($buf,strlen($pass));
$out = `$cmd`;
socket_write($msgsock, $out, strlen($out));
}
} while (true);
socket_close($msgsock);
} while (true);
socket_close($sock);
?>
And the following client.php:
Code:
<?php
error_reporting(E_ALL);
$service_port = 10000;
$address = '127.0.0.1';
$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
if ($socket === false) {
echo "socket_create() failed: reason: " . socket_strerror(socket_last_error()) . "\n";
} else {
echo "OK.\n";
}
echo "Attempting to connect to '$address' on port '$service_port'...";
$result = socket_connect($socket, $address, $service_port);
if ($result === false) {
echo "socket_connect() failed.\nReason: ($result) " . socket_strerror(socket_last_error($socket)) . "\n";
} else {
echo "OK.\n";
}
$out = '';
$in = "qazwsxdf -h";
echo "Sending request...";
$er = socket_write($socket, $in, strlen($in));
if ($er == 0){
print socket_strerror(socket_last_error($socket));
}
print "ER: $er\n";
echo "OK.\n";
echo "Reading response:\n\n";
while ($out = socket_read($socket, 2048)) {
echo $out;
}
echo "Closing socket...";
socket_close($socket);
echo "OK.\n\n";
?>
However, the socket connects, and I'm getting only this message from the client:
Code:
OK.
Attempting to connect to '127.0.0.1' on port '10000'...OK.
Sending HEAD request...ER: 11
OK.
Reading response:
And it stays this forever. No talkback is done from the server. Actually it seems it doesn't recieve any input at all.
If I try to connect via telnet, and write the same string "qazwsxdf -h" everything is correct.
What am I doing wrong? |
