To clarify, the socket server is remote or local, the php code is always
local.
Turns out one of the libraries on the remote server is using unicode, 4
bytes to the character. Thus the string it is trying to return is 4
times as long as the string length.

Description:
------------
I have a php script running on apache that reads a string from a TCP
socket on a server. Using the below script on a local server works. I
cannot get it to return more than 1305 bytes remotely. The remote server
reports sending the whole string (about 4K bytes) back.
The following is a short version of the code below:
while(($sting = socket_read($socket, $slen, PHP_BINARY_READ)) !==
false) {
$out = $out.$sting;
if(strlen($out) >= $slen) break;
}
I get a warning that the socket closed, then the string:
<b>Warning</b>: socket_read() [<a
href='function.socket-read'>function.socket-read</a>]: unable to read
from socket [104]: Connection reset by peer in
<b>/usr/local/apache2/htdocs/mikidel.php</b> on line <b>473</b><br />
"returnstringabcdefg....."
using php 5.3.3 w Apache/2.2.14 (Unix) PHP/5.3.3 on Centos 5 ( redhat
clone)
./configure --enable-xml --enable-dom --with-openssl --enable-sockets
--enable-debug --with-config-file-path=/etc --with-curl --with-zlib
--enable-ftp --enable-soap --with-sybase-ct=/sybase
--with-libxml-dir=/usr --prefix=/usr/local/apache2/php
--with-config-file-path=/usr/local/apache/php --with-gettext
--with-apxs2=/usr/local/apache2/bin/apxs
php.ini standard vanilla
note that the remote socket is C code, and I have tried using
write(socket...) and send(socket...). Both work locally since there are
no \n or \r. Neither work remotely.
Test script:
---------------
// Create a TCP/IP Socket
$socket = socket_create (AF_INET, SOCK_STREAM, 0);
if ($socket < 0) { echo "socket() failed: reason: " . strerror
($socket) . "\n"; }
// Connect to Target
$result = socket_connect ($socket, $address, $service_port);
if ($result < 0) { echo "connect() failed.\nReason: ($result) " .
strerror($result) . "\n"; }
$tmp = socket_read ($socket, 6, PHP_BINARY_READ);
$slen = (int)($tmp-6);
$out = (string)$tmp;
$sting = socket_read($socket, $slen, PHP_BINARY_READ);
$out = $out.$sting;
while(($sting = socket_read($socket, $slen, PHP_BINARY_READ)) !==
false) {
$out = $out.$sting;
if(strlen($out) >= $slen) break;
}
// Close Socket
socket_close ($socket);
return $out."\n";
Expected result:
----------------
The script should work remotely since it works locally.
Obviously if I ask for 4k bytes from a remote socket, it should return
4k bytes, since it does so from a local socket.
Actual result:
--------------
<b>Warning</b>: socket_read() [<a
href='function.socket-read'>function.socket-read</a>]: unable to read
from socket [104]: Connection reset by peer in
<b>/usr/local/apache2/htdocs/mikidel.php</b> on line <b>473</b><br />
"returnstringabcdefg....."
