Hello all,
socket_read() is working fine omitting the third parameter
PHP_NORMAL_READ.
I am using php 5.0.4 in WinXP with Apache 2.0.54. Server code is same
as example given in online document with minor modification. Using CLI
the code works fine. I have written a small client and run it from
browser which sends text message to the server. This also working fine.
The only problem I am having now is that I can't run the server code
using browser cause its hanging and using telnet client I can only send
single character. For this reason in my server code I have taken '9' for
Quit and '0' for Shutdown.
Part of the code goes as -
<?php
/* Same as example code in the document and then */
$msg = "\nWelcome to the PHP Test Server. \n";
$msg .= "To quit, type '9'. To shut down the server type
'0'.\n";
socket_write($msgsock, $msg, strlen($msg));
do {
if (false === ($buf = socket_read($msgsock, 2048))) { /*,
PHP_NORMAL_READ*/
echo "socket_read() failed: reason: " . socket_strerror($ret) .
"\n";
break 2;
}
if ($buf == '9') {
$msg1 = "\nLoging out. \n Thanks for using the server";
socket_write($msgsock, $msg1, strlen($msg));
break;
}
if ($buf == '0') {
$msg1 = "\nServer is shuting down. Thanks.";
socket_write($msgsock, $msg1, strlen($msg));
socket_close($msgsock);
break 2;
}
$talkback = "\tHOST : You said " .$buf. "\n";
socket_write($msgsock, $talkback, strlen($talkback));
echo "$buf\n";
} while (true);
echo "Closing client.\n";
socket_close($msgsock);
} while (true);
socket_close($sock);
?>

Configuration : PHP 5.1.0b3 (CLI), Win2000 SP4.
I make my first steps in network dev / sockets and I encounter the same
problem.
A simpler complete test case using PHP-CLI instead of the unreadable
sample given sooner.
I want simply connect the client to the "server" and send the msg
"Hello server !" that will be displayed on the server's console...
server.php
=========================================================
<?php
$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP) ;
socket_bind($socket, '127.0.0.1', 4567) ;
socket_listen($socket) ;
$client = socket_accept($socket) ;
echo socket_read($client, 256, PHP_NORMAL_READ) ; // Line 7
socket_close($client) ;
socket_close($socket) ;
?>
=========================================================
client.php
=========================================================
<?php
$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP) ;
socket_connect($socket, '127.0.0.1', 4567) ;
socket_write($socket, "Hello server !\r\n") ;
socket_close($socket) ;
?>
=========================================================
So, I launch server.php then client.php, result on server console :
=========================================================
PHP Warning: socket_read(): unable to read from socket [0]: Opération
réussie.
in C:\dev\PHP\mines\server.php on line 7
Warning: socket_read(): unable to read from socket [0]: Opération
réussie.
in C:\dev\PHP\mines\server.php on line 7
=========================================================
Same thing with PHP_BINARY_READ or no 3rd parameter specified :
socket_read( ) returns FALSE and warn us.
No error on client console.
Note that all *seems* OK when I use the following server.php :
=========================================================
<?php
$socket = stream_socket_server('tcp://127.0.0.1:4567') ;
$client = stream_socket_accept($socket) ;
echo fgets($client) ; // Outputs "Hello server !"
fclose($client) ;
fclose($socket) ;
?>
=========================================================
So, how should we consider socket extension ? Should we forget it for
stream_*( ) and f*( ) functions ?
Thx :)

I've compilled PHP with cygwin/gcc and no error is produced. However,
the build version from snaps.php.net gives that error.

Ok, this is a short example : (a little echo server)
<?php
error_reporting(E_ALL);
$Port=6669;
if(($Sock=socket_create(AF_INET,SOCK_STREAM,0))<=0) {
echo 'socket_create() a échoué :
',socket_strerror(socket_last_error($Sock)),"\r\n";
exit;
}
if(($Ret=socket_bind($Sock,0,$Port))<=0) {
echo 'socket_bind() a échoué :
',socket_strerror(socket_last_error($Ret)),"\r\n";
exit;
}
if(($Ret=socket_listen($Sock,5))<=0) {
echo 'socket_listen() a échoué :
',socket_strerror(socket_last_error($Ret)),"\r\n";
exit;
}
while(true){
$MsgSock=socket_accept($Sock);
if($MsgSock===false) {
echo 'socket_accept() a échoué :
',socket_strerror(socket_last_error($MsgSock)),"\r\n";
break;
}
else {
echo '=> Debut de la connexion...',"\r\n";
$EndTime=time()+15;
do{
$buffer=socket_read($MsgSock,1024,PHP_NORMAL_READ);
if($buffer===false) {
echo 'socket_read() a échoué :
',socket_strerror(socket_last_error($MsgSock)),"\r\n";
break;
}
elseif(!$buffer){
continue;
}
$buffer=trim($buffer);
echo '< ',$buffer,"\r\n";
if($buffer=='quit') {
break;
}
$back='You sent : ['.$buffer.']';
echo '> ',$back,"\r\n";
socket_write($MsgSock,$back."\r\n");
} while(time()<$EndTime);
@socket_close($MsgSock);
echo '=> End...',"\r\n";
}
}
socket_close($Sock);
?>

If you omit the third parameter to socket_read() it seems to work fine.
However, adding PHP_NORMAL_READ causes error as described in the bug
report.

Hello
I have a source which works with PHP 4.1.x to PHP 4.2.x,
it's work perfectly. But with PHP 4.3RC4 (windows version,
client mode) I have this warning :
Warning: socket_read() unable to read from socket [0]: OpÚration
rÚussie. in E:\PHP\KioobFTP\v0.7.1\KioobFTP_SocketMode.php on line 262
Then, the result of the function is FALSE.
The socket is in blocking mode.
The code is :
$tmp=socket_read($this->stream,4096,PHP_NORMAL_READ);
Do you need others info ?
Thanks.
Bool
