Status: No Feedback
Bug Type: Sockets related
Operating System: Windows\Linux
PHP Version: 5.0.0RC1
New Comment:
You wrote incorrect code a little. You must not check return value of
socket_get_option after socket_connect immediately because some
operations (like socket creation) take a long time to execute, mostly
because they involve talking to another host, which may have an
exruciating long timeout on it.
You should use socket_select and when select (or related interface)
says that the socket is ready for writing, you can call
socket_get_option($SOCKET, SOL_SOCKET, SO_ERROR, ...) on it. And now
socket_get_option will return with the error socket_connect would have
indicated, had it been called in a blocking manner. If the error is 0,
the connect succeeded.
As you remember socket_select have timeout paramer and this parameter
give some time to connect or no socket.

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves.
A proper reproducing script starts with ,
is max. 10-20 lines long and does not require any external

Hi - I have the same issue, althought I am using PHP 5.0RC3 (cli) from
Linux. Here is some of the code that I am using - I added an echo
statement so that I could see what was happening when I connected with
more than one client at a time:
$port = 5000;
if (!$sock = socket_create_listen($port)) {
echo socket_strerror(socket_last_error());
}
if (!socket_set_option($sock, SOL_SOCKET, SO_REUSEADDR, 1)) {
echo socket_strerror(socket_last_error());
}
if (!socket_set_nonblock($sock)) {
echo socket_strerror(socket_last_error());
}
while (true)
{
$msgsock == FALSE;
do
{
@$msgsock = socket_accept($sock);
} while ($msgsock == FALSE);
echo "Received connection from $msgsock\n";

Description:
Hi to all
i'm tring to write a little application with PHP using Socket, the
external module, not fsockopen function or similar.
I've noticed that, with this, and previous version of php, that after i
create a socket and set it as non blocking socket, when i try to connect
using
socket_get_option($SOCKET, SOL_SOCKET, SO_ERROR)
i recive EVER 0
Instead i should recive 115
If socket_get_option, with these params, return 0, it mean that
connection is done and i can send datas, but if i send datas i get a
warning that say that socket is in a connection state so i can't send
datas.
There is some parts of code:
$this->socket[$sock_id]['resource'] = socket_create(AF_INET,
SOCK_STREAM, SOL_TCP);
if (!is_resource($this->socket[$sock_id]['resource']))
die("Unable to create socket! " .
socket_strerror(socket_last_error()) . "\r\n");
if (!socket_set_option($this->socket[$sock_id]['resource'], SOL_SOCKET,
SO_REUSEADDR, 1)) {
die("Unable to set to as REUSABLE socket! " .
socket_strerror(socket_last_error($this->socket[$sock_id]['resource']))
. "\r\n");
after i set socket as reusable (but php gimme me the same problem
without this line too) and, after, if i need, i bind socket to a
specific IP and PORT
after there is this code:
@socket_connect($this->socket[$sock_id]['resource'],
$this->socket[$sock_id]['remote_host'],
$this->socket[$sock_id]['remote_port']);
while (($ris = @socket_get_option($this->socket[$sock_id]['resource'],
SOL_SOCKET, SO_ERROR)) == 115) {
echo "--> " . $ris . "\r\n";
}
echo "\r\n--> " . $ris . "\r\n";
If you run this code it will exit immedatly printing:
--> 0
Infact, after, if you try to write to socket, you will get a warning
I haven't modified php.ini, and i've tried to run this code, using only
socket extension, on windows and on linux
I use apache 1.3.29 on windows and on linux
bye
