PHP - Php Custom Application Server
Would it be possible to create a passive socket server using php, for a client-server php app, that runs as some sort of daemon?
I understand that you probably can't understand much of what I mean, but I hope you understand enough to help me in some way. PHP APPLICATION - > APPLICATION SERVER - > DATABASE(S) Explanation: Each instance of the PHP application would connect to the "Application Server" and use it to fetch information and perform some commands. Could this be done using sockets ? Simple examples would help Thank You! Similar TutorialsHi, I need a small help. Here is my situation. I am using a MVC application (e.g. Joomla or Drupal) which has a .htaccess redirect rule that all requests are passed through index.php file. That's normal and this is my main application. Now I installed another application within the application folder structure. What I want do do here is to allow opening the third party application URLs after one logged into my main application. Can anybody provide me some pointers to do the same? Please let me know if you need any further information on this. Any solution irrespective of framework will work. Thanks! Anupam I'm sure it's not much, but I'm not understanding something with custom error handlers: I've created a custom error handler, which I initially set when my page loads : set_error_handler(array ( new ErrorHandler(), 'handleError' ));
It seems to catch all internal PHP errors, such as if I: var_dump($non_existing_var); right after the set_error_handler.... Now, I have an object that throws an exception after: set_error_handler(array ( new ErrorHandler(), 'handleError' )); $locale = new \CorbeauPerdu\i18n\Locale(...); // this should throw an exception ... I thought that with an error handler set, I could 'skip' the try/catch for it, but doing so, PHP spits out in its internal log: PHP Fatal error: Uncaught CorbeauPerdu\i18n\LocaleException: ....
My error handler doesn't catch it at all before, thus my page breaks!! If I want it to go through the error handler, I have to init my Locale with a try/catch and use trigger_error() like so:
set_error_handler(array ( new ErrorHandler(), 'handleError' ));
try {
$locale = new \CorbeauPerdu\i18n\Locale(...); // this should throw an exception
}
catch(Exception $e) {
trigger_error($e->getMessage(), E_USER_ERROR);
}
...
Is this normal ? I thought one of the goals of the error_handler was to catch anything that wasn't dealt with? Thanks for your answers! 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? 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"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>TITLE</title> <meta name="keywords" content=""> <meta name="Description" content=""> <? include("common/dochead.php"); ?> </head> <body onLoad="<? include('common/preloads.php'); ?>"> <!-- ============================ main ============================= --> <div id="main-frame"><div id="main" class="noCollapse"> <? include("common/sign.php"); ?> <div id="right-frame"> <? include("common/navigation.php"); ?> <div id="content-frame"> <div id="content"> <h1>Welcome</h1> <p>This is the content area.

I have spent many hours on this. Regards 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>
Edited Wednesday at 12:49 AM by bee65 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. 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? Edited by Zane, 15 July 2014 - 11:28 PM. 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 Hey. I am wanting to move a couple of files from my current server to another. If i am uploading the file this is fine but if it is already on the server then im not sure how to move it. When uploading I can just use ftp_put($conn_id, $destination_file, $myFile, FTP_BINARY); What i need to do is figure out how to get a hold of the file and store it in $myFile then this would work fine. Is this possible? Cheers (This might be the wrong forum; it might be server-side configuration, but alas it is the code that *calls* fwrite, so I'll start here.) I have written a script, and one thing it does is generate a file to disk using fwrite. No big deal. Here's what interests me: On most servers, the file is written successfully when the folder's permissions are 755 with recursive permissions. On some servers, 755 fails. Only 777 works. How could this be? Are permissions=permissions=permissions? Why will 755 work on one machine but not another? I'm just a logic guy; I know very little of server-side configuration and/or why there would be a difference here. Just trying to learn. I am urgently looking for a junior PHP web application developer with a portfolio of your code experience, no commercial experience will be considered to.
Please contact me to find out more!
Exciting opportunity for someone wanting to get a foot in the door in the world of IT!!
Hey all I have an error in my Facebook application and I'm not sure what's wrong (New to PHP).

Can someone take a look at my scripts and fixed please [attachment deleted by admin] There are ten list or bookmarks from Prof. Horner's Bible-Reading System found (http://www.facebook.com/group.php?gid=46416541831) each having set number of books from the Bible. One is to read ten chapters a day, one chapter from each of the bookmarks. Type in what day you are on and the program will show you on each of the lists as to what chapter you are suppose to be on. Also want to show statistics that will display how many times the Bible has been read with a break down of all 66 books of the Bible.

I am building program to manage payment/monthly payments. I've ran into an issue that I haven't been able to overcome and need some help. I've been lurking for a while and decided it was time to ask you guys...Here's the issue: I have a table 'payments' that contains scheduled payments that looks like: id clientid paymentduedate balance expected pending 367 112233 4/16/2011 1030.00 257.50 Y 368 112233 5/16/2011 1030.00 257.50 Y 369 112233 6/16/2011 1030.00 257.50 Y 370 112233 7/16/2011 1030.00 257.50 Y What I need to do that I haven't figured out is to adjust the expected amount according to the payment, update the status to N (not pending) without affecting the later expected payments. For example: they make a payment of $257.50, applies that to row 367, sets the status to N, but leaves the other status' to Y (for obvious reasons). the make a payment of $250.00, leaving the balance at $7.50, so lets add $7.50 to row 368, mark 367 status to N the make a payment of $300.00, leaving the expected balance at $0.00 for row 367, but adjust the balance for row 368 to $215.00 Any ideas? Thanks Hi all, this is my first time on this forum! I have a background with HTML and CSS but have recently started a Masters in Computer Science hoping to come out of it with the tools to get a job with PHP development. Our first assignment has somewhat 'thrown me in the deep end' as we have to construct a search engine that indexes the words of a number of documents and rank them using the TF*IDF algorithm along with the log rule associated with Information retrieval. I am completely new to PHP so the past week has been something of a crash course - This is the code I have so far: Code: [Select] <?php $filename = 'airlines.txt'; $fp = fopen( $filename, 'r' ); $file_contents = fread( $fp, filesize( $filename ) ); fclose( $fp ); //$new_contents = ereg_replace("[^A-Za-z0-9]", "", $file_contents); /*$file_contents = trim($file_contents); $file_contents = preg_replace('/\h+/', ' ', $file_contents); $file_contents = preg_replace('/\v{3,}/', PHP_EOL.PHP_EOL, $file_contents); */ $pat[0] = "/^\s+/"; $pat[1] = "/\s{2,}/"; $pat[2] = "/\s+\$/"; $rep[0] = ""; $rep[1] = " "; $rep[2] = ""; $new_contents = preg_replace("/[^A-Za-z0-9\s\s+]/","",$file_contents); $new_contents = preg_replace($pat,$rep,$new_contents); //preg_replace('~\s{2,}~', ' ', $text); $commonWords = array('a','able','about','above'........and another few hundreds cut out of this not to hurt your eyes!); $lines = explode ( "\n", $new_contents); $lines2 = implode (" ", $lines); $words = explode ( " ", $lines2 ); $useful_words = array_diff( $words, $commonWords ); /*for($i = 0; $i < count($lines); $i++) { echo "Piece $i = $lines[$i] <br />"; }*/ for($i = 0; $i < count($useful_words); $i++) { echo "Words $i = $useful_words[$i] <br />"; } //$arr=array("blah1","blah2","blah3"); file_put_contents("demo2.txt",implode(" ",$useful_words)); //$file_c = file_get_contents("demo.txt"); //$colms = explode(",",trim($file_c)); //print_r($colms); //echo $lines[2]; ?> I've got to the stage where that strips out most of the stop words when the final array is printed, but they have been replaced with spaces or something that I have not come acoss because as you may see I had a bit of trouble originally stripping the punctuation marks. I'm hoping someone can point me in the direction as to how to organise the words I have left after the stripping of stop words which are of no use during the search. I need to store those words into another array and index them which says how many times they appear in that document. I've come across the function array array_count_values ( array $input ) on the manual but I'm not sure about the best way to use it. I've attached the files I've used if that helps. Any help would be greatly appreciated! |
