CodeIgniter: The Future of PHP Web Development

As a PHP developer since the introduction of PHP3, I always insisted on creating my scripts from scratch. I believed that starting from an empty text file was the best, fastest and most lightweight solution. This was what I have been doing for the past years until I read up more about PHP frameworks.

I was extremely skeptic about frameworks, I told myself that PHP is way too advanced already and a framework is simply overkill, that if I needed anything, I would code it myself and take care of it. I ran into CodeIgniter and I was very impressed by their “Blog in 20 minutes” video (which in all honesty can be done in 5 or 10 minutes if the video maker did not go into details). Also, it is open source and accessible to everyone.

We have recently introduced a new dedicated server configuration utility when making orders for our clients (check it out, follow this link and click on “configure server” for any other listed servers: xeon dedicated servers). We had to take care of this and obviously have it up as soon as possible. I had reviewed and checked CodeIgniter so I decided to give it a shot for this project.

Deliver much faster results
The results were incredible, the entire utility was done in less than 2 days which seems incredible for the amount of code that would have been required if I did not have a framework, there are numerous places where a lot of time was saved because of CodeIgniter.

Built in form verification was a great time saver; CodeIgniter makes it extremely easy to take care of validating web forms by using a library, verifying the input of the user is as simple as writing the following:

$this->form_validation->set_rules('username', 'Username', 'required');
$this->form_validation->set_rules('password', 'Password', 'required');
$this->form_validation->set_rules('passconf', 'Password Confirmation', 'required');
$this->form_validation->set_rules('email', 'Email', 'required');

if ($this->form_validation->run() == FALSE)
{
$this->load->view('myform');
}
else
{
$this->load->view('formsuccess');
}

More about this is explained on CodeIgniter’s documentation regarding Form Validation. There are tons of different ways and libraries/classes that permit you to get more done in much less time.

Easily create expandable and modular PHP code
CodeIgniter is based on the common concept of “MVC” code, MVC stands for model-view-controller, the three aspects or modules of the application or script that you’re developing. Each aspect focuses on taking care of something specific, the views is basically what the client sees (you could possible call it template), but it’s basically what the client sees, the “controller” is the back-end where everything is executed and everything is programmed there, the models are basically common functions or classes that you’re using

While I tried my best explaining it, the best way to understand MVC coding is by actually giving it a shot and also referring to CodeIgniter documentation regarding the model-view-controller software approach.

Give it a shot.
The amount of time saved has made us switch over from our own code to running everything through the framework; it simply makes everything so much organized and makes modifications a swift. The amount of time saved plus the impressive software approach leaves your program to be extremely modular and easily expanded.

Installing WordPress 2.5 on WordPress hosting

Wordpress is one of the class leading blogs and the one of the most used from personal to enterprise size blogs, proved stability by hosting popular blogs for even automotive manufacturers, most of the people enjoy the facility of the administrator control panel however the installation process behind it is slighty complicated however it depends on what type of hosting do you have.

VEXXHOST WordPress hosting
All of our plans include Fantastico, so instead of going through this whole document in the pain of installing WordPress it, all you need to do is enter Fantastico from your control panel in cPanel, click on “WordPress”, insert the path you want it installed, the username and password for the administrator panel and you’re ready and good to go

Other web hosting platforms

• Head to the WordPress website page http://wordpress.org/download/ and click on “Download”, it should download a zip file that you will place somewhere on your hard disk and unzip it, you’ll have a bunch of folders and files starting with wp
• Upload the extracted folderto your account, you should usually check with your provider’s control panel as there are different ways to login via FTP, we cannot go in detail about every single control panel out there however asking your support staff should help you. A free and good FTP client is SmartFTP at http://smartftp.com
• Create a new clean MySQL database, again this is something that is control panel specific, the procedure is very different from control panel to control panel however in cPanel, it is the easiest to be done using a Wizard, more information and a video tutorial is included here, http://www.cpanel.net/media/tutorials/mysqlwizard.htm — Make sure you get a MySQL username, password and database name to continue our installation.
• Rename the wp-config-sample.php to wp-config.php and replace the fields for it to appear something like the following
  define('DB_NAME', 'putyourdbnamehere'); // The name of the database
define('DB_USER', 'usernamehere'); // Your MySQL username
define('DB_PASSWORD', 'yourpasswordhere'); // ...and password
  Most of the time, you will not need to modify your DB_HOST unless your hosts tell you too, after uploading the renamed wp-config.php file into the main root directory of your hosting, simply go to http://yourdomain.com/dir/wp-admin/install.php where dir is the directory you uploaded WordPress to, if you uploaded it to the root directory of your account, then simply go to http://yourdomain.com/wp-admin/install.php and following the instructions.

That’s basically it for installing WordPress on your web hosting, as you can see the method is a lot easier when using Fantastico with our affordable web hosting platform, happy blogging!

Web hosting datacenter proximity, does it matter?

A lot of users who are looking for web hosting usually take the location into matter to add to the complicated equation when looking for a web hosting company however it is not always the most important factor. It’s not completely unimportant but it is important to some point, you would at least want to have the datacenter at least in the same continent.

Of course, you won’t get the best speeds off your web hosting company if you are located in North America, it wouldn’t be the smartest idea to get your web hosting somewhere in southern Asia as it will be very slow & will be crawling for you and most of your clients if they are located in North America.

However, if you do take web hosting in a place such as Montreal, QC which is 5 hours north of New York, NY – The speed will not be that much different if it was actually located in Montreal, QC or New York, NY because the difference between the two is close to nothing at the speeds that the internet runs at.

To conclude, the best idea is to get your web hosting services at a company close to you but not necessarily very close but not necessarily very far that your web site would be very slow.

Top 5 new (and cool!) features in PHP5 that you probably haven’t heard of

PHP5 has brought so much new features but because of its big syntax changes, a big percentage of the PHP developing base has not made the change. Here are the top 10 new features that could change your mind.

5: Better error handling with exceptions
I’m sure every PHP developer had been staring at the famous white screen with a “Syntax error” clueless at where the error is really at. With PHP5, you can actually handle PHP errors and do whatever you want with them, but that’s not all. They have also included exceptions which I’m sure most C++ or Java developers use. The good part is that instead of simply failing on with close no errors to you, you could put a few checks before and information you could need such as maybe a print_r() on an array. I have written an article about this: http://vexxhost.com/blog/?p=21

4: Completely rewritten MySQL extension
The MySQL databases are the PHP’s partner in crime. Many developers use this database system in their website’s because it is on of the easiest, free, open-source database software. However, its performance combined with PHP4 was close to poor. Introduced with PHP5 is a newer, rewritten, optimized MySQL extension which was also compatible with MySQL 5.0. It has also introduced other functions such as: Prepared statements, SSL connections, Multi-query functions.

3: A heck of a lot more useful functions
I have a few favorite PHP5 functions which speed up time while coding & enhances the website’s performance. One of my favorites is the __autoload() function – What it does that it would be called if a class that was created and did not exist. It provides you with the class name. This is useful because you don’t need to manage what includes you need for X and Y file and reduces the load for those who simply include all the classes in for every single PHP file. Also, another favorite is file_put_contents() which reduces the 6 lines of code to add something to one.

2: Finally! SQLite database support!
I’m sure a lot of developers will be happy about this one. While MySQL is very popular among most PHP developers, SQLite is much different than it. It actually uses normal files and reads them. It does not need a daemon (or called server) to run in order to execute any queries on it. It makes a better smaller database for these low traffic sites.

1: The best damn OOP support period
PHP programmers have spent an awful of long time trying to create hacks so in order that PHP can make a better OO programming language. Finally, they are rewarded with OO support that either PHP3 or PHP4 can match. It has anything you usually see in most of the other established coding languages. From Constructors, Destructors, Public, protected, private properties & methods, Interfaces, Abstract classes, Class type hints, Static properties and methods, Final properties and methods & a whole suite of magical methods.

That’s the top 5 for me. I hope you think that PHP5 deserves a try! (and we offer it with our hosting plans!)
