Looking for assistance with creating a PHP adapter for the binary API of OrientDB, specifically regarding socket communications.
Struggling to establish a connection between PHP and OrientDB, seeking help from someone familiar with raw socket communication in PHP.
If you have experience working with sockets, please check out this link for details on the issue I am facing.
Once we overcome the initial hurdle of sending a packet (refer to simplified examples at the bottom of the link), I can proceed with developing the adapter.
This project will be open source once completed.
Any assistance in getting started would be greatly appreciated. Thank you!

Attempting to use PEAR's Net_Socket, but encountering challenges similar to those faced when using fsockopen() and regular PHP stream functions.
The server does not respond, causing the script to hang indefinitely until surpassing the general PHP time limit, despite setting a timeout.
Provided below is the code snippet being used:
<?php
header('Content-type: text/plain');
error_reporting(E_ALL | E_NOTICE | E_WARNING);
$txid = 123;
$db = 'demo';
$username = 'writer';
$password = 'writer';
// Packet creation
$packet = "\x05". # 1 byte
pack('i',$txid). # 4 bytes
pack('i',strlen($db)).$db. # string
pack('i',strlen($username)).$username. # string
pack('i',strlen($password)).$password; # string
hex_dump($packet);
$addr = '127.0.0.1';
$port = 2424;
$timeout = 5;
$errstr = '';
$errno = 0;
// Opening socket connection
$socket = fsockopen($addr, $port, $errno, $errstr, $timeout);
stream_set_blocking($socket, 1);
socket_set_timeout($socket, $timeout);
var_dump($socket);
fwrite($socket, $packet);
$response = '';
// Reading response from socket
while (!feof($socket))
$response .= fread($socket, 1024);
hex_dump($response);
fclose($socket);
Additionally, here is the hex_dump() function utilized to analyze submitted packets:
<?php
function hex_dump($data, $newline="\n")
{
// Function logic
}
As per Luca Garulli's assessment, the packet structure appears correct. Hence, the issue seems to stem from another source...
Could this problem be related to Windows compatibility? The setup involves PHP 5.3 running on Windows, under Apache...
