opening it again, as this seems a different issue.
We should have the EAGAIN constant and use it for non-blocking sockets.
returning false isnt't a good idea.

Please do not submit the same bug more than once. An existing
bug report already describes this very problem. Even if you feel
that your issue is somewhat different, the resolution is likely
to be the same.
Thank you for your interest in PHP.
See bug #21197

I`m look everyware in the Internet and don`t find any workaround for
this problem. And error logs still growing...
This code decreases count of warnings:
-- code --
$startTime = microtime_float(true);
socket_send($socket, $package, strLen($package), 0);
socket_set_block($socket);
$to = array('sec' => 0, 'usec' => 500000);
socket_set_option($socket, SOL_SOCKET, SO_RCVTIMEO, $to);
if (socket_read($socket, 4096)) {
socket_close($socket);
return microtime_float() - $startTime;
}
socket_close($socket);
-- end of code --
my "ping" function launches once per 5 minutes for around 50 hosts, but
not all of them alive. Dead hosts causes warnings.

I`m not agree what it is bogus....
part of code from ext/sockets/sockets.c:
-- code --
if (type == PHP_NORMAL_READ) {
retval = php_read(php_sock->bsd_socket, tmpbuf, length,
0);
} else {
retval = recv(php_sock->bsd_socket, tmpbuf, length,
0);
}
if (retval == -1) {
PHP_SOCKET_ERROR(php_sock, "unable to read from
socket", errno);
efree(tmpbuf);
RETURN_FALSE;
}
-- end of code --
As you can see any processing for EAGAIN not exists. Warning will be
generated in any case.
1. I`m developing icmp ping function and "no reply" is not an error in
my program.
2. Function, what can say is any data to receive, not exists.
3. I do not want to turn warnings off. Because I need them in other
places.

Description:
------------
Use of socket_read() on non blocking sockets produces warinigs like:
socket_read() unable to read from socket [35]: Resource temporarily
unavailable
I`m storing all php errors in log file /var/log/php.log.
This warning causes overflow of /var partition because socket_read()
called to wait icmp message.
Reproduce code:
---------------
$socket = socket_create(AF_INET, SOCK_RAW, 1);
socket_connect($socket, $host, null);
$startTime = microtime_float(true);
socket_send($socket, $data, strLen($data), 0);
socket_set_nonblock($socket);
while((microtime_float() - $startTime) < 0.5) {
$mt = microtime_float();
if (socket_read($socket, 255)) {
break;
}
}
socket_close($socket);
Expected result:
----------------
no warnings in php.log
Actual result:
--------------
I`m receive huge count of warinigs in my php.log file like this:
socket_read() unable to read from socket [35]: Resource temporarily
unavailable
