In this tutorial we will be looking into Doctrine Record Hooks. This will allow us to trigger certain actions in our Models.
We are going to use this feature to simplify a few things in the existing code, and even gain some performance benefits.
Cron Jobs are used for scheduling tasks to run on the server. They’re most commonly used for automating system maintenance or administration. However, they are also relevant to web application development. There are many situations when a web application may need certain tasks to run periodically. Today we are going to explore the fundamentals of Cron Jobs.
Today, we continue our journey into the world of SQL and relational database systems. In this part three of the series, we’ll learn how to work with multiple tables that have relationships with each other. First, we will go over some core concepts, and then will begin working with JOIN queries in SQL.
Today we will be working on Pagination.
Mastering cURL
Jan 16
cURL is a tool for transferring files and data with URL syntax, supporting many protocols including HTTP, FTP, TELNET and more. Initially, cURL was designed to be a command line tool. Lucky for us, the cURL library is also supported by PHP. In this article, we will look at some of the advanced features of cURL, and how we can use them in our PHP scripts.

It is important for every web developer to be familiar with database interactions. In part two of the series, we will continue exploring the SQL language and apply what we’ve learned on a MySQL database. We will learn about Indexes, Data Types and more complex query structures.

SQL for Beginners

Another article published on Nettuts

Most modern web applications today interact with databases, usually with a language called SQL. Lucky for us, this language is quite easy to learn. In this article, we are going to start with some basic SQL queries and use them to interact with a MySQL database.
In this article we are going to create Templates (with CodeIgniter) to keep our Views organized, and avoid repeating the same HTML code. Also we are going to learn about Doctrine Data Hydrators to see alternative ways to structure the data returned from the database.
My third article for Nettuts was just published:
“Code readability is a universal subject in the world of computer programming. It’s one of the first things we learn as developers. Readable and maintainable code is something to be proud of in a finished product. We can share it with others, contribute to other projects, and reuse code from applications we wrote months or even years ago.
This article will detail the fifteen most important best practices when writing readable code.”
In this article we are going to look at 3 main subjects: Hooks (with CodeIgniter), Doctrine Profiling and DQL. And we are going to see how we can use these to optimize some of our database interactions.
HTTP Headers for Dummies
Dec 2
My second article for Nettuts was just published:
http://net.tutsplus.com/tutorials/other/http-headers-for-dummies/
Whether you’re a programmer or not, you have seen it everywhere on the web. At this moment your browsers address bar shows something that starts with “http://”. Even your first Hello World script sent HTTP headers without you realizing it. In this article we are going to learn about the basics of HTTP headers and how we can use them in our web applications.
Top 20+ MySQL Best Practices

Nettuts+ just published my article!

Database operations often tend to be the main bottleneck for most web applications today. It’s not only the DBA’s (database administrators) that have to worry about these performance issues. We as programmers need to do our part by structuring tables properly, writing optimized queries and better code. Here are some MySQL optimization techniques for programmers.
Today we will continue building our Message Board project. First we will start building the Home Page, which will be a Forum List. Then we will learn about Doctrine Data Fixtures. This will help us create some test data to play with.
In this episode of the series, we will continue building our Message Board project. First we will have a quick overview of Doctrine Model Relationships. Then we will create Models for our Message Board, such as: Forums, Threads, Posts etc… with proper relationships. Finally we will learn how to add data into such Models.
CRUD stands for Create, Read, Update and Delete, the basic operations performed on the database. With regular CodeIgniter setups, most developers would use the Active Record Class for performing such operations. But we are not going to be doing that.
In this episode of the series, I will show you how to perform CRUD with Doctrine.
PHP Frameworks have been receiving a lot of attention in the past few years from the web development community. What’s this hype all about?
If you look at PHP Job listings, you will often see “MVC Framework Experience” as one of their requirements. It is becoming one of those must-have skill sets for web developers.
There are pretty good reasons behind all of this. In this article we will explore why you, as a PHP programmer, should be using a PHP Framework.
In this episode we are going to build a User Signup Form following these steps:
- We build a Login Form View and a Login Controller.
- Learn about some URL Helpers.
- Change the Default Controller.
- Implement User Authentication.
- Learn about Singleton Pattern and use it to improve our code design.
- Learn about the Sessions Library.
- Implement User Logout.
In this episode we are going to build a User Signup Form following these steps:
- We build a “User” Model with Doctrine.
- Learn about Mutators.
- Create tables using Doctrine.
- Remove index.php from CodeIgniter urls
- Build and Style the Signup Form.
- Learn about Helpers, Libraries and how to extend them.
- Form Validation and checking for duplicates.
In this episode:
- We do a quick fresh install of CodeIgniter and Doctrine, without going into details like last episode.
- Briefly go over some of the basic concepts of CodeIgniter and Doctrine.
- First we will review Controllers and Views in CodeIgniter.
- Then we will move on to Models using Doctrine. This is where things are going to get a little different, compared to other CodeIgniter tutorials out there.
- Finally we will preview a sample Doctrine Model and talk about what our main project is going to be.
Quick Disclaimer: Even if you know about PHP5 Method Chaining, don’t skip this article, because we will explore more than just that.
If you’re familiar with jQuery, you might know how it let’s you write short and clean code with the help of method chaining.
Not only will I show you how to accomplish this in PHP5, but I will also combine this feature with magic setter methods with the help of method overloading to make it even nicer.
It’s OK if you don’t know any of these terms. You should still be able to become familiarized with them by reading this article.
