PHP - Applicable Ways To Store State On The Server Using Php
Hello, mates! I am new to PHP. I want to store some data shared between requests. I know that it is possible with memcached and shared memory in Unix. What ways to do it could you advice? How could I realize background service in PHP? Thank you.
Similar TutorialsHello,
I've noticed that there are services that I can pay to have my code
checked for possibly unsafe / insecure code.
But I'd rather audit the code myself, as my code is not meant to make money.
Is there a list of safe ways to use PHP?
Also is there any automatic way to do this that is free?
For instance is there a code checker?
I've noticed there are a number of ways to do PHP wrongly
that can be easy to overlook. Is there a list of common PHP pitfalls?
Thanks.
Is there a shorter way to achieve this in a single foreach()? foreach ($_SESSION['cart']['content']['sizes'] as $content); foreach ($_SESSION['cart']['content']['sizem'] as $content); foreach ($_SESSION['cart']['content']['sizel'] as $content); I am thinking something like: foreach ($_SESSION['cart']['content']['sizes'] && $_SESSION['cart']['content']['sizem'] && $_SESSION['cart']['content']['sizel'] as $content); or foreach ($_SESSION['cart']['content'] = ['sizes'] || ['sizem'] || ['sizel'] as $content); I would realy like to study php, other than taking other codes and editing them i havnt got a clue. Hi all If there a better way of setting variables within classes than taking it through the __construct and setting via $this ?? e.g. class SectionsConnect { protected $var; public function __construct($var){ $this->var= $var; } } Can you not set the variable automatically as it comes in through the __construct? Thanks Magnetica What would be the simplest way? Do you use a method in the child class? Personally I use Code: [Select] parent::$this->whatever; But I was wondering what you guys do. Is this an acceptable way to instantiate classes?
//$_SESSION['product'] = {'ProductA', 'ProductB', ... 'ProductX'}
$p = new $_SESSION['product']();
$p->save();
I am usually used to calling out classes explicitly where class name is not a variable but a hardcoded string. Sometimes I use if/then/else in order to do this. Here it is a variable and it bothers me a little bit. But PHP allows me to do this.
Is this an acceptable latest & gratest modern PHP object oriented web technology technique or not ?
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>
Edited Wednesday at 12:49 AM by bee65 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 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? Edited by Zane, 15 July 2014 - 11:28 PM. I added <?php $_menu = ''?> <?php foreach ($this->getStoreCategories() as $_category): ?> <?php $_menu .= $this->drawItem($_category) ?> <?php endforeach ?> <?php if ($_menu): ?> <div class="nav-container"> <ul id="nav"> <li class="level0 first nav-home"><a href="<?php echo $this->getUrl() ?>"><span><?php echo $this->__('Home') ?></span></a></li> <?php echo $_menu; ?> <li class="level0 nav-1 parent"><a href="<?php echo $this->getUrl('contacts')?>"><span><?php echo $this->__('Contact') ?></span></a></li> <?php echo $this->getLayout()->createBlock('cms/block')->setBlockId('menu')->toHtml() ?> </ul> </div> <?php endif; ?> to top.phtml and it works as expected, I now have CMS links in my nav but how can I make them have active state like the category links do?? here is the site: http://pro-tools-training.com/new-magento/index.php/video-1.html (This might be the wrong forum; it might be server-side configuration, but alas it is the code that *calls* fwrite, so I'll start here.) I have written a script, and one thing it does is generate a file to disk using fwrite. No big deal. Here's what interests me: On most servers, the file is written successfully when the folder's permissions are 755 with recursive permissions. On some servers, 755 fails. Only 777 works. How could this be? Are permissions=permissions=permissions? Why will 755 work on one machine but not another? I'm just a logic guy; I know very little of server-side configuration and/or why there would be a difference here. Just trying to learn. Hey. I am wanting to move a couple of files from my current server to another. If i am uploading the file this is fine but if it is already on the server then im not sure how to move it. When uploading I can just use ftp_put($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 $myFile then this would work fine. Is this possible? Cheers I have a class (P3TElement) that extends the DOMElement class in PHP. In there i have a public variable "attributes" which is an array, and an method named add_attribute($attr), the argument is a different class (P3TAttribute). However I am getting an error when trying to use it. The exact error is: Warning: P3TElement::add_attribute() [p3telement.add-attribute]: Invalid State Error in D:\www\p3textract\extract.php on line 110 Please see the code: http://pastebin.com/CbsM9V5W This class is supposed to extract .p3t (ps3 themes) files, and is a direct port of the python equivalent found at http://p3textractor.googlecode.com/svn/trunk/p3textractor.py Could you please help me fix this? thanks in advance, Hosh Hi I'm hoping someone can point me in the right direction. I'm trying to create a single page that contains a couple of checkboxes. When the first checkbox is checked I want to set a session. When the second chechbox is checked I want to set a different session. When the page submits ( to itself ) I'd like the checkboxes to reflect if they are checked or not. I can sort of do that part,but I'm having major issues with unsetting the sessions and updating the checkboxes to reflect this. Does anyone have a simple example on how to do this. Many Thanks Is there a way, and if so how would I detect the state of the user on my site. Like by using their ip? Thanks! In this report I want to create a line break and a Total line for each State.
while ($row = odbc_fetch_array($result))
{
echo "<tr><td>" . $row['cmlstate']."</td>";
echo "<td>" . $row['cmlpostcode']."</td>";
echo "<td>" . $row['cmlcity']."</td>";
echo "<td>" . $row['ompSalesOrderID']."</td>";
echo "<td>" . $row['cmoName']."</td>";
echo "<td>" . number_format($row['UOMPVOLUMETOTAL'],2)."</td>";
echo "<td>" . number_format($row['UOMPTOTALBOXCOUNT'],0)."</td>";
echo "<td>" . $row['Hold']."</td></tr>";
I want to sum 'UOMPVOLUMETOTAL' for each state and create a line break between it and the next state.
}
