PHP - Server Port?

Hi! I'm trying to make an button that when it's pressed sends an http post to my home server. But my home server is runing on port 84 and i think that i'm not being able to send the post correctly because of this port. any help?   my code now is this:

	$ch = curl_init();

	
	curl_setopt($ch, CURLOPT_URL, "http://homeserver.net:84/?device=35");
	curl_setopt($ch, CURLOPT_HEADER, 0);
        curl_exec($ch);
	curl_close($ch);

The way I have the URL is correct?   thanks!

Hi all, I want to send a string of data to serial port. Below is the code. Sdata contains the string. for example "<LT-ON-50>".

<?php
exec("mode com3: BAUD=600 PARITY=n DATA=8 STOP=1 to=off dtr=off rts=off");
if (isset($_GET['action'])) {
    $SData = $_GET['action'];
    $fp = fopen("com3","w");
    fwrite($fp,$SData);
    fclose($fp);
}
?>

unfortunately, it will send only one character i.e '<'. the remaining characters will be lost. What could be wrong in the code. Any help can be greatly appreciated. Thanks,  

Okay, I'm using fsockopen to see if a port is being used, But all it does it crashes the page if it isn't. If it is one it works but if it is off the pages just doesn't load at all.

Code:
<?php
$fp=fsockopen("localhost", 43594, $errno, $errstr, 30);
if($fp){
echo('The server is <font color="#0066FF"><b>Online!</b></font>');
} else {
echo('The server is <font color="#FF0000"><b>Offline!</b></font>');
}
?>

Can one of you amazing helpful souls help me out? Thanks in advance!

Hi,

I'm trying to connect to a database on a port other than 3306 to create a database. Here's my connect code:

$connection = new MySQLi($host,$user,$pass)()

But according to the PHP website it says I can lay the code out like so:

new MySQLi($host,$user,$pass,$database,$port)()

But how do I specify the port without the database? I've tried just "" as the database but the connection still fails.

Any help would be much appreciated.

Hi.  I am writing a web app to control Zoom Player on my HTPC.  I found that ZP supports listening on a TCP port to accept control commands.  The docs say to quit ZP, send 5100,fnExit + ASCII 13/10 to port 4769.  My original client was C# and I implemented it there, works great.  I then realized WTF am I doing using an external .EXE to just send data to a TCP port?  Switched to using PHP's fsockopen.  Alas, that causes an error to pop up on ZP (List index out of bounds or some such).  Perplexed,  I wrote a GUI for the HTPC to just display an ASCII val breakdown of what it receives to compa



So it looks like they both send the data the same.      Any idea why the discrepancy?

Here is the code:

C# that works:
Code: [Select]
    string cmdstr = "";
    for (int x=2; x<=args.Length-1; x++) cmdstr += args[x] + " ";
    if (SendCommand(args[0], System.Convert.ToInt16(args[1]), cmdstr.Trim() + Environment.NewLine)) Console.WriteLine("Command string sent.");
    Environment.Exit(0);

    static bool SendCommand(string dest, int port, string cmd) {
      try {
        IPAddress[] ips = Dns.GetHostAddresses(dest);
        TcpClient client = new TcpClient();
        IPEndPoint serverEndPoint = new IPEndPoint(ips[0], port);
        client.Connect(serverEndPoint);
        NetworkStream clientStream = client.GetStream();
        ASCIIEncoding encoder = new ASCIIEncoding();
        byte[] buffer = encoder.GetBytes(cmd);
        clientStream.Write(buffer, 0, buffer.Length);
        clientStream.Flush(); clientStream.Close(); clientStream.Dispose();
        client.Close();
        return true;
      } catch (Exception ex) {
        Console.WriteLine("Failed: " + ex.Message);
        return false;
      }
    }

The PHP that is being difficult:
Code: [Select]
  send_data("lioth", "4769", "5100,fnExit");

  function send_data($host,$port,$data='') {
    $fp = fsockopen($host,$port);
    if($fp) {
      fputs($fp, "$data\r\n");
      fclose($fp);
    }
    return;
  }

 

I have a small project. I have a control board that is connected to the parallel port.

It controls 8 strips of LED on the LPT1 port.

I can turn these on and off via the command prompt, using LPTOUT.exe   ie lptout 1  turns on the 1st LED

lptout 2  will turn off 1st LED and turn on 2nd,  lptout 4 turns on 3rd and 2nd off, etc
 1, 2, 4, 8, 16, 32, 64, 128.     and combinations ie lptout 3  turns on LEDS 1 and 2, and so on.

However lptout seems very unresponsive sometimes I have to do lptout 1  twice before LED 1 turns on.

Is there another command I can use to write to LPT1 port.

I need some PHP code to control the outputs.

I want to sequence the outputs ie  1on (1second) 2on (1 second) 3 on (1 second) 4 on  etc. to 8, then all off then repeat.

Can anyone help me.

THANK YOU.

Hello guys,

I am new to PHP programming. I am trying to figure out how to use PHP language to transmit/write characters to a USB port device at 9600 baud rate 8-N-1. Basically I just need the PHP coding to allow me to send stuff to the USB device but I have no idea how I can interface this. I did some researching but most were for RS-232 COM Port. I can't find the proper one for USB.

If someone can help me out, that would be awesome. Thank you!

I have a PHP web system that store in a windows server. In the system, there is a function for user to upload files to another server (Shared server in Unix).

When i try to upload a file, it gives warning:

Warning: move_uploaded_file(\\unixserver/sharedfolder/upload/test.txt) [function.move-uploaded-file]: failed to open stream: Permission denied in C:\wamp\www\upload\index.php on line 40

For your information, my username has been assigned in xxx's group that has access to read and write on that folder. Besides, i'm able to open,create and delete files on that folder's server manually (samba).

The safe mode setting is off.

Does anybody has any idea why this thing happen?

I'm trying to make a simple website where people register to my website.

When the user doesn't fill anything inside the boxes they get a message "Please fill all required fields" on the register.php page

On my local host require_once works good. It shows up.

 

But when i upload the files to my sever the require_once does not show up on the register.php

It just refreshes and i dont get the message "Please fill all required fields"

 

This is the code that works in local host but not in a live server

<?php require_once 'messages.php'; ?>

 

 

Here is my full code

 

Register page:

<html>


<?php require_once 'messages.php'; ?>

<br><br>


<form action="register-clicked.php" method="POST">

Username:<br>
<input type="text" name="usernamebox" placeholder="Enter Username Here">
<br><br>
Email:<br>
<input type="text" name="emailbox" placeholder="Enter email here">
<br><br>
Password:<br>
<input type="password" name="passwordbox" placeholder="Enter password here">
<br><br>
Confirm Password:<br>
<input type="password" name="passwordconfirmbox" placeholder="Re-enter password here">
<br><br>

<input type="submit" name="submitbox" value="Press to submit">
<br><br>

</form>

</html>

 

 

Register clicked

<?php


session_start();



$data = $_POST;

if( empty($data['usernamebox']) ||
    empty($data['emailbox']) ||
    empty($data['passwordbox']) ||
    empty($data['passwordconfirmbox'])) {
    $_SESSION['messages'][] = 'Please fill all required fields';
    header('Location: register.php');
    exit;

}




if ($data['passwordbox'] !== $data['passwordconfirmbox']) {
    $_SESSION['messages'][] = 'Passwords do not match';
    header('Location: register.php');
    exit;
}


$dsn = 'mysql:dbname=mydatabase;host=localhost';
$dbUser='myuser';
$dbPassword= 'password';

try{
$connection = new PDO($dsn, $dbUser, $dbPassword);
} catch (PDOException $exception){
    $_SESSION['messages'][] = 'Connection failed: ' . $exception->getMessage();
    header('Location: register.php');
    exit;
}

 

 

messages.php

<?php
session_start();

if (empty($_SESSION['messages'])){
    return;
}

$messages = $_SESSION['messages'];
unset($_SESSION['messages']);
?>



<ul>
    <?php foreach ($messages as $message): ?>
        <li><?php echo $message; ?></li>
    <?php endforeach; ?>
</ul>

Hi,  I am not a PHP programmer.

I took on a new client with a simple PHP site, without any databases.
The site is up and running on the web.
I would like to get it running on my local machine for further development.
I have latest version of WAMP installed, running Apache version 2.2.11 and PHP version 5.3.0
I created a directory in the WAMP "www" project directory and it shows up there like it's supposed to when I browse to "localhost"

Problem:

The home page of website displays text but no, images, styles, footer, header, nav links, etc.


Here is the code for the home page:

<?
  define("NAV","home");
require_once('local/local.php');
?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

    <meta name="Description" content="">

<? include("common/dochead.php"); ?>

    </head>

<body onLoad="<? include('common/preloads.php'); ?>">

Any help would be greatly appreciated. I have spent many hours on this.

Hi folks,

I'm curious if I can for example, save a file from my server and it will save to all other servers - obviously if they accepted the connection first. It's for a software I developed and is almost complete and know there will be frequent updates to it. Instead of users downloading upates, I want the update files from my server to somehow synchronize to their server automatically?

Anything called this??

Thanks for info.

Following a tutorial on udemy, i tried to learn the very basics of mvc structure. I built the same project on my local server and it worked without giving me any error. but when i tried it on live server. its not working as it should. not showing any error. I tried to figure out the problem and found that for every page loading, it stops at the same line in my main.php file.

<?php require($view); ?>

starting from the above line. it stops. i came here to share my problem but i am unable to upload my files here. if there is a way to upload and share my files, please guide. zip file size of the whole project is 31.6 kb

This isn't exactly an application design question, but rather a system design one.   I am about to install an Inventory Control System inside this store I work in.   The store itself also owns a Linode VPS running Centos 6.4 which hosts our website.   This new Inventory System will come built in with a Microsoft SQL Server, and supposedly it is a SQL Anywhere database, but I'm not too sure what that means.     I need to make this database publicly accessible, but only via the Linode VPS.  Surely, setting restrictions is easy enough to address that issue.  That isn't my question.   My first idea is to put this server into the DMZ, easy.  But it doesn't exactly sound safe.  So my next idea was to put a middleman server in the DMZ, this way the Linode can send queries to that middleman server and it will send that data to the SQL Server and back.  This is very vaguely described I know, but I don't want to get too much into details, but rather, understand how I can create that middleman server, and what could Install onto it that would allow me to securely process queries?   My first thought was to install a webservice, that accepts an XML/JSON request and returns an XML/JSON response. Then, I realized directly afterwards that I don't have any experience setting up a webservice like that. What kind of options are there out there?
  Ultimately, my question is, should I just put the Server in the DMZ or should I create the middleman, and if so, can someone point me in the right direction as to getting a webservice set up?
