Here's the code!
How can i get the return by 'socket_read()"?

/get the post "01 booklist select from contentlist"/
$sql = "select from music";

error_reporting(E_ALL);

/ Get the port for the WWW service. /
$service_port = 5000;

/ Get the IP address for the target host. /
$address = '192.168.0.142';

/ Create a TCP/IP socket. /
$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
if ($socket < 0) {
echo "socket_create() failed: reason: " . socket_strerror($socket) . "\n";
} else {
echo "\n";
}

$result = socket_connect($socket, $address, $service_port);
if ($result < 0) {
echo "socket_connect() failed.\nReason: ($result) " . socket_strerror($result) . "\n";
} else {
echo "\n";
}

//$out = '';

socket_write($socket, $sql, strlen($sql));

while ($out = socket_read($socket, 0, PHP_BINARY_READ)) {
echo "right";
}

socket_close($socket);

....
while ($out = socket_read($socket, 0, PHP_BINARY_READ)) {
[/B]

Not that I've used the socket_* functions that much, but according to what the manual says about [man]socket_read[/man], the second argument is supposed to be the maximum number of bytes read from the socket. You have zero there.

Hi,

try this code:

$data = "";
while ($out = socket_read($socket, 512, PHP_BINARY_READ) !== false) { 
  $data .= $out;
}

Hi,

do you run that script on a Windows server or a UNIX/Linux server ? Which PHP version do you use ?

Thomas

Redhat7.3
Apache HTTP Server Version 1.3
PHP Version 4.1.2

Then i changed the php version;

Redhat7.3
Apache HTTP Server Version 1.3
PHP Version 4.3.4
(Configure Command './configure' '--with-mysql' '--with-apxs' '--enable-sockets' )

But here 's the same error message .

:queasy:

Hi,

what kind of service are you trying to connect to ?
You first send a command to the service (the select). Could it be that the service expects a special character at the end of the command like e.g. \n ?

Look at these lines:

/get the post "01 booklist select from contentlist"/
$sql = "select from music";

Does the comment contain an example ? Then try something like
$sql = "01 musiclist select * from music";
or something like that ... I'm just guessing since I don't know the service.

You might try something like this:

$sql = "select * from music\n";
