Bug #55814 [NEW]: stream_socket_recvfrom() ârandomlyâ returns false
From:
Operating system: Windows 7
PHP version: Irrelevant
Package: Streams related
Bug Type: Bug
Bug description:stream_socket_recvfrom() ârandomlyâ returns false
Description:
------------
Sometimes, on Windows7 with PHP5.3+, stream_socket_recvfrom() returns false
(the documentation says that it always returns a string but the source code
says the opposite, it can return false), and I have no idea why. It happens
only on Windows7 a priori. Basically, I have a client and a server as
bellow.
Test script:
---------------
Client.php
<?php
$client = stream_socket_client(
'tcp://127.0.0.1:9001',
$errno,
$errstr,
30,
STREAM_CLIENT_CONNECT
);
echo 'Received ';
var_dump(stream_socket_recvfrom($client, 6));
Server.php
<?php
$server = stream_socket_server(
'tcp://127.0.0.1:9001',
$errno,
$errstr,
STREAM_SERVER_BIND | STREAM_SERVER_LISTEN
);
echo 'Up & listenâ¦', "\n";
$client = stream_socket_accept($server);
echo 'New connection', "\n";
stream_socket_sendto($client, 'foobar');
echo 'Sent âfoobarâ', "\n";
Expected result:
----------------
Client.php
Received: string(6) "foobar"
Server.php
Up & listenâ¦
New connection
Sent âfoobarâ
Actual result:
--------------
Client.php
Sometimes: Received: string(6) "foobar"
Sometimes: Received: bool(false)
Server.php
Up & listenâ¦
New connection
Sent âfoobarâ
