PHP Tutorials Examples Model View Controller MVC Model View Controller MVC by Kevin Waterson Contents Abstract Model View Controller. This tutorial will take you from the beginning to the end of building a MVC framework. What is MVC? MVC is a design pattern. In the MVC framework that is created in this tutorial, several key points will be raised. It is beyond the scope of this tutorial to show how to set up htaccess and mod_rewrite and more information on these can be gained from the Apache manual. RewriteEngine on RewriteCond %{REQUEST_FILENAME} ! RewriteRule ^(.*)$ index.php? The .htaccess file will permit access to the site via urls such as If you do not have mod_rewrite available, the entry to the site will be the same, except that the URL will contain the values needed such as: The Site Structure In this tutorial several directories are required to hold the various components that make up the MVC framework. html application controller includes model views .htaccess index.php
Hallmarks of a Great Developer - Test Guide If you ask me, I'll tell you a great developer Plans before coding A great developer takes the time to plan an approach before designing or coding. A great developer knows that the time required to do so will be more than paid back by the time saved by getting it more right the first time. Always knows why A great developer always knows exactly why they wrote a particular line of code, and why they wrote it the way they did. Writes situation-appropriate code Any developer can write code. Deviates where and when necessary A great developer not only knows the canonical implementation but understands it is the canonical implementation. Knows when not to change code A great developer knows that changing code is sometimes worse than fixing it. Approaches debugging scientifically A great developer knows that debugging is a science not an art and approaches it as such. Walks through their code A great developer knows that they don't really know their code until they've stepped through it. Documents
Développer son propre micro-framework MVC en PHP Imaginons que vous avez besoin de réaliser une API REST qui cause en JSON. Vous aimez bien les trucs simple et super rapide. Donc utiliser un framework à la Zend ou Symfony est totalement overkill même avec Silex. Et puis comme vous aimez réinventer la roue vous avez décidé de développer votre propre micro-framework minimaliste. Notre framework MVC Voici les fonctionalités que l'on veut mettre en oeuvre : Séparation modèle, vue et contrôleurAucune dépendance, doit pouvoir fonctionner sans d'autres bibliothèques PHPLe plus simple possibleRapideDoit pouvoir appeler un contrôleur en fonction d'une URL et d'une méthode HTTP (GET, POST, PUT, DELETE). On va diviser notre framework en plusieurs parties : Request : Gère la requête HTTPRouter : Execute une action en fonction de l'URL et du verbe HTTPResponse : Retourne la réponse au client qui peut-être du JSON Implémentation Voici ce que l'on veut obtenir, une requête GET sur la ressource /team/123 doit nous retourner une réponse en JSON. <?

Model View Controller(MVC) in PHP Tutorial The model view controller pattern is the most used pattern for today’s world web applications. It has been used for the first time in Smalltalk and then adopted and popularized by Java. At present there are more than a dozen PHP web frameworks based on MVC pattern. Despite the fact that the MVC pattern is very popular in PHP, is hard to find a proper tutorial accompanied by a simple source code example. The MVC pattern separates an application in 3 modules: Model, View and Controller: The model is responsible to manage the data; it stores and retrieves entities used by an application, usually from a database, and contains the logic implemented by the application. The above figure contains the MVC Collaboration Diagram, where the links and dependencies between figures can be observed: Our short php example has a simple structure, putting each MVC module in one folder: Controller include_once("controller/Controller.php"); $controller = new Controller(); $controller->invoke(); viewbook.php
How to Prevent Image Bandwidth Theft With .htaccess Protect your images from being linked by other websites while you pay the bandwidth! by Christopher Heng, thesitewizard.com If your website displays beautiful pictures, you may encounter the ugly situation where your photos and other images are used without your permission on other sites. Even worse, those websites "hotlink" your pictures, that is, they don't host the pictures directly on their site, but embed them into their pages by linking to the copy on your site. System Requirements The solution outlined in this article requires your site to be hosted on a machine using the Apache web server. If this is not the case for your website, you cannot use the suggestions given here. (To find out if your web server fulfills the requirements stated here, try checking up the documentation on your web host's website — the information is usually available on their list of web hosting packages, price lists or on their order form. Steps to Take That's all there is to it. Potential Problems
Write your own PHP5 MVC framework : the blog of ndungi kyalo Let there be Lite Although there are as many frameworks out there as there are programmers, very few frameworks allow the programmer room to code his/her own way. Most are bloated with libraries and features you will never use. Enough with the sales pitch. (From Wikipedia) Model–View–Controller (MVC) is an architectural pattern used in software engineering. In simpler words- 1. So with such a nice introduction we get down to it! In the beginning We want our application to be at -> to list all contacts in the db – to delete contact with the id 12 and so on and so forth .. So we start off by creating the project directory `contacts`. Options -Indexes RewriteEngine on RewriteCond %{REQUEST_FILENAME} ! Basically, the above rules allow you to implement pretty urls in the application. Note that your apache installation needs to have the directive AllowOverride set to All. index.php <? <? if (!

Build PDF files dynamically with PHP Sometimes you need control over exactly how pages are rendered for printing. At times like those, HTML is not the best choice. PDF files give you complete control over how pages are rendered and how text, graphics, and images are rendered on the page. When you search the web for PDF support for PHP, the first thing you are likely to find is the commercial PDFLib library and its open source version, PDFLib-Lite. Another choice is the Free PDF library (FPDF), which is native PHP. To demonstrate building PDF files dynamically, you'll use scores from women's roller derby tournaments. Listing 1. <events><event name='Beast of the East 2011'><game score1='88' team1='Toronto Gore-Gore Rollergirls' team2='Montreal La Racaille' score2='11'/><game score1='58' team1='Toronto Death Track Dolls' team2='Montreal Les Contrabanditas' score2='49'/> ... The root element for the XML is an events tag. Listing 2 shows the PHP code that you use to read the XML. Listing 2. getresults.php <? Listing 3. Figure 1.
Creating a PHP5 Framework - Part 1 With websites becoming more and more dynamic and interactive, developers often look to frameworks to help build websites and web apps rapidly. While there are a number of great frameworks available, a custom framework gives you the ability to easily customize the framework as you need, and to build with it even quicker - as you would already know the ins and outs of it before working with it. In this series of tutorials, we are going to build our very own PHP5 Development Framework! Let's start with planning our framework and put the basic structure into place. *Note - Running the demo should display "PCA Framework version 0.1 the HTML output" - which demonstrates the first stage of our framework. Step 1: This Series In this series, we will create our own PHP5 Framework from scratch. Over the next few weeks, during these tutorials we will cover: Step 2: Design Patterns and their use within our Framework Step 3: Files and Folders Some commonly used functions / objects.Business logic.A design
.htaccess Tutorial Introduction In this tutorial you will find out about the .htaccess file and the power it has to improve your website. Although .htaccess is only a file, it can change settings on the servers and allow you to do many different things, the most popular being able to have your own custom 404 error pages. .htaccess isn't difficult to use and is really just made up of a few simple instructions in a text file. Will My Host Support It? This is probably the hardest question to give a simple answer to. A good sign of whether your host allows .htaccess files is if they support password protection of folders. What Can I Do? You may be wondering what .htaccess can do, or you may have read about some of its uses but don't realise how many things you can actually do with it. Creating A .htaccess File Creating a .htaccess file may cause you a few problems. Warning Before beginning using .htaccess, I should give you one warning.

The Joel Test: 12 Steps to Better Code by Joel Spolsky Wednesday, August 09, 2000 Have you ever heard of SEMA? It's a fairly esoteric system for measuring how good a software team is. No, wait! The neat thing about The Joel Test is that it's easy to get a quick yes or no to each question. A score of 12 is perfect, 11 is tolerable, but 10 or lower and you've got serious problems. Of course, these are not the only factors that determine success or failure: in particular, if you have a great software team working on a product that nobody wants, well, people aren't going to want it. 1. 2. If the process takes any more than one step, it is prone to errors. For this very reason, the last company I worked at switched from WISE to InstallShield: we required that the installation process be able to run, from a script, automatically, overnight, using the NT scheduler, and WISE couldn't run from the scheduler overnight, so we threw it out. 3.

PHP Frameworks? Just roll your own! – PART 1 There are quite a few php frameworks out there. Some huge, some small; Some useful, some not. I often hear developers, even myself, complain about frameworks in php not having or not doing something the way they/we want it too. So my solution? Roll your own framework! Mini-series Overview Week 1: URL Routing and Directory SetupWeek 2: TemplatingWeek 3: Database Interaction To get started let’s setup our directory structure. MyWebApp/ '---actions/ '---helloworld/ '--- actions.php '--- models.php '--- templates/ '--- yourTemplateHere.php '---system/ '--- template.php '--- database.php '--- dispatch.php '---www/ '--- js/ '--- css/ '--- images/ '--- index.php Let’s break this structure down, it’s simple. MyWebApp: the root of your web app that will be using our “Peanut” framework Now that we have a directory structure, let’s setup a virtual host in Apache to accommodate for Peanut. And In my /etc/hosts file I add this line: So now let’s get to some code. So, inside dispatch.php, let’s add:
Tools To Make Your Web Development More Efficient John K. Taylor Are you a developer who is sick and tired of having to do everything manually? Does sifting through your code to hunt down tiny mistakes make you want to scream? Then perhaps some of these web development tools will come in handy for making your work more efficient. CSS Grid Builder This is a framework that was developed by Yahoo! Clean AJAX This tool has been designed to speed up AJAX development, which is just not possible when done manually. CSS Sprite Generator This tool has been designed to reduce the number of HTTP requests are needed for rendering images in web browsers. Firebug This is an extension created by Mozilla Firefox that gives a developer a wide range of web development tools and features that they otherwise may not have had access to. CSSTidy This tool is an open source application that aims to reduce file size through analyzing text, fixing and optimizing the CSS code. This useful article is shared by John K.
Roll Your Own PHP Framework: Part II A little over a week ago, we looked at how to set up our file structure and how to get URL routing working in our little framework. So we now have something to handle urls and display a page, but we want to make the page a little more attractive. Since there is nothing fun about making php print html, let’s add a template piece to the puzzle. We won’t have to do too much since php is a great template language by itself. Mini-series Overview Part 1: URL Routing and Directory SetupPart 2: TemplatingPart 3: Database Interaction Note: I’m assuming you have a little OOP (Object Oriented Programming) experience. We are going to create a class Template and add a little code to it so it will return our pretty new page to our browser. Wipe out system/template.php and add the following code to it: Well hello templating! require(PEANUT_ROOT_DIR . ’system/template.php’); Right underneath the dispatch.php require statement. So inside actions/helloworld/templates/helloworld.php template put the following:
