  • How does PhP internally represent string?

    - by Jim Thio
    UTF8? UTF16? Does the string in PhP also keep tracks the encoding used for that string? A good answer would give me a sample of Let's look at this script for example. Say I do $original = "??????????????"; What actually happen? Obviously I think $original will not contain just 7 characters. Those glyps must each be represented by several bytes there. Then I do $converted= mb_convert_encoding ($original , "UTF-8") What will happen to $converted? How will $converted be different than $original? Will it be just the exact same byte sequence with $original but with different encoding? Or what?

What would I put between the code below? <Location /password-protected> ...mysql password protection require valid-user </Location>

  • Writing a desktop application for progammer from PHP background

    - by Mark
    I have a client who wants a tool for him to be able to upload his products, enter orders, and keep track of customer details. There are quite a few highly customised requests, which is why he wants the tool custum made. He does not care much about the interface design - it just has to be usable and provide access to the databade. I've already designed the database. I have no experience of desktop applications and usually write my web apps in PHP with the Yii framework. But hosting this on a server seems like overkill. I also have .net experience from a few years ago. What would be the best options for writing this as a desktop application?

  • Passing variables from PHP to C++

    - by Alex
    I’m new to this so I’m sorry if my question is trivial. I have the following situation: I need to call a program from PHP and pass some vars and/or sets of key-value pairs to it. Now, my question is: how do I pass these vars, through arguments to the called function (e.g. exec("/path/to/program flag1 flag2 [key1=A,key2=B]");)? Or is there a better method to achieve this? Somebody suggested me to write them into a txt file and pass the path to it to as an argument instead (e.g. exec("/path/to/program path_to_txt_file);), but I’m not to excited about this method.

  • PHP OOP: Am i following right way?

    - by sineverba
    I'm learning OOP (PHP). I've realized my own CRUD Class, that performs some kind of queries SQL. Btw, a Gasoline asked us to realize a smart, simple web-app where he can update prices of his gasoline (gasoline, diesel, lpg) and via an API i could recall them and display in his site. So, I did create a new Class Gasoline but it perform some methods of CRUD Class public function getPrezzoBenzina($id) { $prezzo_benzina = $this->distributore->sql('SELECT prezzo_benzina FROM prezzi WHERE id = '.$id); return $prezzo_benzina } And so on (code is pseudocode, just to explain). I could perform all my code only with help of Crud Class... without necessity of Class Gasoline. So, what I'm missing about OOP? Where am I wrong?

  • What to choose for beginner: PHP/Python/Ruby

    - by Nai
    I'm a beginner teaching myself to code but I would like he insight of the PSE community and helping choose where to start. My main objective is to be able to create a basic website to first test my business idea and from there iterate on it quickly to minimise my learning time. The most important criteria for me is speed. An example of speed would be pre-built components available open source and not having to write one from scratch. From my research, this seems to be a death match between the following languages and frameworks: PHP and CakePHP Python and Django Ruby and Rails Assumptions: I am going to be equally good (or bad) in all 3. It is going to be equally easy to find competent developers in either language. I know this to be false already by lets assume that it is. This question is not meant to karma whore as I've seen how passionate some of these standoff questions have been and I'll be happy to turn it into a community wiki.

  • Architectural advice - websockets javascript/php integration

    - by Ewan Vaentine
    Myself and a friend have started making a game, he's likely to be using impact.js for the user interaction etc, but we need multiplayer functionality so some form of websockets for TCP connections etc. So we were thinking impact.js into socket.io and node.js. However, user accounts, ecommerce, session handling and social media integration will all be handled with Codeigniter (PHP), my question is, is it wise to have node.js running in parallel with Codeigniter, or if this is even possible? If not, if you were to create a multiplayer online game utilising ecomms to buy credits and user accounts, how would you go about this from a structural position and what engines/frameworks would you recommend? I'm new to this site so I apologise in advance if I'm posting something inappropriate. Cheers, Ewan

  • Need private personal access to ~three PHP pages

    - by Roger
    I would like secure access to the text output by three PHP scripts (the text output is JavaScript and html) . The security level is much less then financial data but important none-the-less. I have considered purchasing AND studying https and SSL certificates. Hostgator charges an extra $2/month for a private ip plus $50+ anually for a certificate. This is more then I want to spend for this project (time + money). Is there a simpler solution that is: less expensive easier to implement. I'm open to different approaches.

  • OOP PHP make separate classes or one

    - by user2956219
    I'm studying OOP PHP and working on a small personal project but I have hard time grasping some concepts. Let's say I have a list of items, each item belongs to subcategory, and each subcategory belongs to category. So should I make separate classes for category (with methods to list all categories, add new category, delete category), class for subcategories and class for items? Or should I make creating, listing and deleting categories as methods for item class? Both category and subcategory are very simple and basically consist of ID, Name and parentID (for subcategory).

  • Web host that handles excess php mailing [closed]

    - by CyberJunkie
    Possible Duplicate: How to find web hosting that meets my requirements? I'm having trouble choosing a host that meets my application's needs. Please kindly inform me what I should look for when choosing a web host. My application is similar to a reminder service that reminds users of events that they scheduled. I'm sending emails to users through a PHP script. I'm not sending one email to multiple recipients. Each recipient receives a different message. I plan to use cron jobs every minute and expect the application to send roughly 200 individual emails in 1 hour (for a small user base that may grow). I don't have hosting experience with this type of application. I plan to start on a shared host and move up in the future to vps or dedicated. Most shared hosts that I looked into allow 50-100 emails per hour with delays between mailings. What do you recommend?

  • Better php framework for shared hosting

    - by ravz
    I need to develop an app for booking appointments. This is gonna be hosted in a shared server. So performance is the most important thing. I have used symfony2. I quite liked the framework. But seems to be heavy. Which framework would suit me considering my requirements? I have shortlisted three frameworks yii, symfony2 and ZF2. I am not asking which framework is better. All the three are good frameworks. I want to know which will suit my requirements. My first priority would be performance (I will be using AJAX wherever possible), second would be maintenance and development time and third community support. Or should I use my own handlers to separate views and logic and just use raw php?

  • PHP class data implementation

    - by Bakanyaka
    I'm studying OOP PHP and have watched two tutorials that implement user login\registration system as an example. But implementation varies. Which way will be more correct one to work with data such as this? Load all data retrieved from database as array into a property called something like _data on class creation and further methods operate with this property Create separate properties for each field retrieved from database, on class creation load all data fields into respective properties and operate with that properties separately? Then let's say I want to create a method that returns a list of all users with their data. Which way is better? Method that returns just an array of userdata like this: Array([0]=>array([id] => 1, [username] => 'John', ...), [1]=>array([id] => 2, [username] => 'Jack', ...), ...) Method that creates a new instance of it's class for each user and returns an array of objects

  • php cms withouth database

    - by user1791795
    A friend of mine asked me for a easy website for him. As it was just 3 subpages, no database need or anything, I've done it quite fast with plain PHP, HTML, JS and CSS. But then another and another friend showed up. They only wanted arrange differently they navigation, some different picutures etc. So I though, is there any kind of CMS, that allows build small business website (barbershop, local groceries shop), with small list of subpages, yet allowing us to arrange look'n'feel. There's no need for the databas as content won't change, or can be stored in simple textfiles for example. Things like WordPress might be simple overkill Does anyone know such cms?

  • PHP statements, HTML and RSS

    - by poindexter
    Alrighty, I've got another little bit of code that I'm wrestling through. I'm building a conditional sidebar. The goal is to only show blog related stuff when posts in the "blog" category are being viewed. I've got part of it working, but the part where I'm trying to bring in an RSS feed of the category into the sidebar to show as recent posts. It doesn't work, and since I'm a php newb I'm not entirely sure why. Any suggestions or pointers are much appreciated. I'll post the problem section first, and then the entire php file second, so you all can see the context for the section that I'm having issues with.

  • /phpTest/zologize/axa.php? Another botnet?

    - by M132
    Starring at the log made me think, what is /phpTest/zologize/axa.php and why are bots looking for it? Previously, I had lots of /HNAP1/ requests. Requesting /HNAP1/ from IPs from log revealed, that all of them were sent by Linksys routers. 3 months later, these requests turned out to be generated by a router worm called TheMoon.

  • A PHP design pattern for the model part [PHP Zend Framework]

    - by Matthieu
    I have a PHP MVC application using Zend Framework. As presented in the quickstart, I use 3 layers for the model part : Model (business logic) Data mapper Table data gateway (or data access object, i.e. one class per SQL table) The model is UML designed and totally independent of the DB. My problem is : I can't have multiple instances of the same "instance/record". For example : if I get, for example, the user "Chuck Norris" with id=5, this will create a new model instance wich members will be filled by the data mapper (the data mapper query the table data gateway that query the DB). Then, if I change the name to "Duck Norras", don't save it in DB right away, and re-load the same user in another variable, I have "synchronisation" problems... (different instances for the same "record") Right now, I use the Multiton pattern : like Singleton, but multiple instances indexed by a key (wich is the user ID in our example). But this is complicating my developpement a lot, and my testings too. How to do it right ?

  • Best PHP framework for an experienced PHP developer?

    - by andybaird
    Okay, before I start this, I am well aware of how subjective this question is. For my case, I'd like to define the 'best' for me as: Rapid development "Pretty" URLs Data validation Good knowledge base available Not impossible to integrate other PHP software with This is a pretty generic definition, but all I'm looking for here is opinions. Edited: Here's a better way to ask this question: You have two weeks to create a full scale booking and scheduling system that accepts Google Checkout payments (via the API) and integrates with an open source message board software. Which framework do you choose and why?

    Example: javascript: var mycourses=new Array(); mycourses[0]="History"; mycourses[1]="Math"; mycourses[1][0]="Introduction to math"; mycourses[1][1]="Math 2"; mycourses[1][2]="Math 3"; PHP will then run these values through functions (please note values are mostly not strings as in the example above but rather numbers), the functions will return some text which will than be displayed in a form How should I go about doing this? p.s.: I found some similar stuff, but nothing quite like this... as far as I see I will have to use JSON (is there a way to code it from JS automatically - saw this for strings) and AJAX

  • Type Casting variables in PHP: Is there a practical example?

    - by Stephen
    PHP, as most of us know, has weak typing. For those who don't, PHP.net says: PHP does not require (or support) explicit type definition in variable declaration; a variable's type is determined by the context in which the variable is used. Love it or hate it, PHP re-casts variables on-the-fly. So, the following code is valid: $var = "10"; $value = 10 + $var; var_dump($value); // int(20) PHP also alows you to explicitly cast a variable, like so: $var = "10"; $value = 10 + $var; $value = (string)$value; var_dump($value); // string(2) "20" That's all cool... but, for the life of me, I cannot conceive of a practical reason for doing this. I don't have a problem with strong typing in languages that support it, like Java. That's fine, and I completely understand it. Also, I'm aware of—and fully understand the usefulness of—type hinting in function parameters. The problem I have with type casting is explained by the above quote. If PHP can swap types at-will, it can do so even after you force cast a type; and it can do so on-the-fly when you need a certain type in an operation. That makes the following valid: $var = "10"; $value = (int)$var; $value = $value . ' TaDa!'; var_dump($value); // string(8) "10 TaDa!" So what's the point? Can anyone show me a practical application or example of type casting—one that would fail if type casting were not involved? I ask this here instead of SO because I figure practicality is too subjective. Edit in response to Chris' comment Take this theoretical example of a world where user-defined type casting makes sense in PHP: You force cast variable $foo as int -- (int)$foo. You attempt to store a string value in the variable $foo. PHP throws an exception!! <--- That would make sense. Suddenly the reason for user defined type casting exists! The fact that PHP will switch things around as needed makes the point of user defined type casting vague. For example, the following two code samples are equivalent: // example 1 $foo = 0; $foo = (string)$foo; $foo = '# of Reasons for the programmer to type cast $foo as a string: ' . $foo; // example 2 $foo = 0; $foo = (int)$foo; $foo = '# of Reasons for the programmer to type cast $foo as a string: ' . $foo; UPDATE Guess who found himself using typecasting in a practical environment? Yours Truly. The requirement was to display money values on a website for a restaurant menu. The design of the site required that trailing zeros be trimmed, so that the display looked something like the following: Menu Item 1 .............. $ 4 Menu Item 2 .............. $ 7.5 Menu Item 3 .............. $ 3 The best way I found to do that wast to cast the variable as a float: $price = '7.50'; // a string from the database layer. echo 'Menu Item 2 .............. $ ' . (float)$price; PHP trims the float's trailing zeros, and then recasts the float as a string for concatenation.

  • PHP Based session variable not retaining value. Works on localhost, but not on server.

    - by Foo
    I've been trying to debug this problem for many hours, but to no avail. I've been using PHP for many years, and got back into it after long hiatus, so I'm still a bit rusty. Anyways, my $_SESSION vars are not retaining their value for some reason that I can't figure out. The site worked on localhost perfectly, but uploading it to the server seemed to break it. First thing I checked was the PHP.ini server settings. Everything seems fine. In fact, my login system is session based and it works perfectly. So now that I know $_SESSIONS are working properly and retaining their value for my login, I'm presuming the server is setup and the problem is in my script. Here's a stripped version of the code that's causing a problem. $type, $order and $style are not being retained after they are set via a GET variable. The user clicks a link, which sets a variable via GET, and this variable is retained for the remainder of their session. Is there some problem with my logic that I'm not seeing? <?php require_once('includes/top.php'); //first line includes a call to session_start(); require_once('includes/db.php'); $type = filter_input(INPUT_GET, 't', FILTER_VALIDATE_INT); $order = filter_input(INPUT_GET, 'o', FILTER_VALIDATE_INT); $style = filter_input(INPUT_GET, 's', FILTER_VALIDATE_INT); /* According to documentation, filter_input returns a NULL when variables are undefined. So, if t, o, or s are not set via URL, $type, $order and $style will be NULL. */ print_r($_SESSION); /* All other sessions, such as the login session, etc. are displayed here. After the sessions are set below, they are displayed up here to... simply with no value. This leads me to believe the problem is with the code below, perhaps? */ // If $type is not null (meaning it WAS set via the get method above) // or it's false because the validation failed for some reason, // then set the session to the $type. I removed the false check for simplicity. // This code is being successfully executed, and the data is being stored... if(!is_null($type)) { $_SESSION['type'] = $type; } if(!is_null($order)) { $_SESSION['order'] = $order; } if(!is_null($style)) { $_SESSION['style'] = $style; } $smarty->display($template); ?> If anyone can point me in the right direction, I'd greatly appreciate it. Thanks.
