Write your own PHP MVC Framework (Part 1) | anant garg. What is MVC? From Wikipedia– Model–View–Controller (MVC) is an architectural pattern used in software engineering. Successful use of the pattern isolates business logic from user interface considerations, resulting in an application where it is easier to modify either the visual appearance of the application or the underlying business rules without affecting the other.
In MVC, the model represents the information (the data) of the application; the view corresponds to elements of the user interface such as text, checkbox items, and so forth; and the controller manages the communication of data and the business rules used to manipulate the data to and from the model. In simpler words- 1. Model handles all our database logic. Why should I write my own framework? This tutorial is by no means a comprehensive/definitive solution to your framework needs. So why should you write your own framework? More importantly, you have complete control over your framework. Lets dive right in Coding Conventions.

By placing the navigation inside the stage area (where the image is displayed), we can get it to hover above the image.

Hacking with Google Search. Google is considered to be a powerful search engine that helps millions of users to find fast & easy useful webpages. Nevertheless Google Search can also be a handy tool in the hands of malicious users, spammers & hackers.
In this article we will describe few tricks that can be used in Google Search in order to easily find and access pages that normally should be protected. At the end of the article we will discuss how webmasters can protect their sites from such attacks. Important Notice: The purpose of this article is to inform webmasters about the risks they face and help them secure their websites. How to Access Member Only Areas Lots of forums allow access in some or all of their threads only to their members.
Nevertheless, in some cases the webmasters of those forums allow Google to index the secured pages in order to appear in the search results and increase their SE traffic. If the cache operator is not available try searching for the URL address. Inurl:/view.shtml. How to Really Build Backlinks and Dominate Google. Without a doubt, the most frequent post request I’ve had on this site is a post about link building. I rarely take requests, simply because people rarely know what they really want until you give it to them, but this time things are a little different.
First of all, I have been studying SEO day and night since I was 16 (almost 5 years ago) and I’ve ranked on the first page of Google for some of the most competitive keyphrases in the world. Therefore, I like to think I know quite a bit about the topic and can provide some insights in this space. For those of you who don’t know why links are important, let me just say that if you want to get traffic from the major search engines, they’re crucial.
Links from other sites to your site are basically a ‘vote’ that tell search engines you are trusted and you are a good resource for whatever your content is about. SEO is generally divided into two parts: on-site optimisation and off-site optimisation. 15 Ways to Build Links to Your Site Be Useful. Infographic_Programming_Rackspace_Final_Version.png (1190×12496) 37 Tested PHP, Perl, and JavaScript Regular Expressions. InShare22 A regular expression, also called regex or regexp for short, is simply a piece of code that matches a pattern. Mastering regular expressions can be a difficult chore, and if you don't need them all of the time, the syntax is tricky enough to make the task frustrating or slow as you will constantly need to use a reference sheet.
In order to save you time, I've compiled a list of PHP, Perl, and JavaScript regular expressions for common use cases that have been tested and are ready to go. This isn't a regular expression tutorial or even a reference; you can think of it more as a cheatsheet for when you just need the regex but don't want to put a lot of time into relearning regular expressions. If you're looking for regex tutorials or regex resources, you can find them at the end of the page as well as some additional regex resources.

Last week, I was invited to join 3,000 delegates to what turned out to be the largest entrepreneurship conference in the world. The Global Entrepreneurship Congress 2012 took place in Liverpool, UK (a few words about Liverpool in a moment) and its speakers and panels were selected in order to inspire us into entrepreneurial action.
Upon arriving in Liverpool on the GEC Express Virgin train, chartered for the specific occasion (welcoming speech and random encounter with Sir Richard Branson), I didn’t know what to expect. One of the first things that I found out, to my surprise, was how geeky Liverpool is! It has more scientists than Cambridge and a booming game industry (it’s supposedly second in the UK). Sir Richard Branson was the main ”attraction” for the day and who could blame the the crowd? Q&A with Sir Richard Branson Delegation was the first skill I was forced to learn when I made the jump from a technical to a managerial position. Don’t drop the “ball”!
The End of Pagination. What do you do when you have a lot of things to display to the user, far more than can possibly fit on the screen? Paginate, naturally. There are plenty of other real world examples in this 2007 article, but I wouldn't bother. If you've seen one pagination scheme, you've seen them all. The state of art in pagination hasn't exactly changed much – or at all, really – in the last 5 years.
I can understand paginating when you have 10, 50, 100, maybe even a few hundred items. Once you have thousands of items, you don't have a pagination problem. But perhaps you don't know exactly what you're looking for: maybe you want a variety of viewpoints and resources, or to compare a number of similar items. Once we've chosen a suitable order and a subset of relevant items … do we really need pagination at all? It isn't just oddball disemvowelled companies, either. Pagination is also friction. I'm not necessarily proposing that all traditional pagination be replaced with endless pagination.
SQL date performance problems. Most obfuscations involve DATE types. The Oracle database is particularly vulnerable in this respect because it has only one DATE type that always includes a time component as well. It has become common practice to use the TRUNC function to remove the time component. In truth, it does not remove the time but instead sets it to midnight because the Oracle database has no pure DATE type. To disregard the time component for a search you can use the TRUNC function on both sides of the comparison—e.g., to search for yesterday’s sales: SELECT ... It is a perfectly valid and correct statement but it cannot properly make use of an index on SALE_DATE. “This book is definitively worth having in the company library.” — Joe Celko There is a rather simple solution for this problem: a function-based index. CREATE INDEX index_name ON table_name (TRUNC(sale_date)) But then you must always use TRUNC(date_column) in the where clause.

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! Don't follow that link! It will take you about six years just to understand that stuff. 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. 4. 5. Google Algorithm Changes 1998-2012 [Infographic] 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. Sadly, APIs for building PDF files are not standard parts of the PHP toolkit. Now is the time to bring in a little help. 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.
