If you are doing a migration from v2.2.x to v3.0.0

You Need To Do the Following Changes.

  • Download SDK: https://github.com/facebook/facebook-php-sdk
  • Keep the two classes base_facebook.php and facebook.php with the certificate fb_ca_chain_bundle.crt
  • Include facebook.php in your PHP file.
  • If you’re currently using the PHP SDK (v2.2.x) for authentication, you will recall that the login code looked like this:
include_once("facebook.php"); OR include_once("base_facebook.php");
$facebook = new Facebook(…);
$session = $facebook->getSession();
if ($session) {
// proceed knowing you have a valid user session
} else {
// proceed knowing you require user login and/or authentication
}
  • The login code is now:
include_once("facebook.php");
$facebook = new Facebook(…);
$user = $facebook->getUser();
if ($user) {
// proceed knowing you have a logged in user who's authenticated
} else {
// proceed knowing you require user login and/or authentication
}

Posted on by Jay

CakePHP is an open source PHP based rapid development framework. It offers great run-time infrastructure along with abundant set of libraries for CakePHP developers. Cake PHP development is supported by the MVC (Model View and Controller) architecture which differentiates the programming logic from the data presentation layer.

It also features other programming concepts like Front Controller, Association Data Mapping and Active Record. Along with these, there are numerous other features that make CakePHP one of the most preferred web development frameworks among others.

Let’s take a look at some features here

Wide Community:

CakePHP developers are supported by huge peers who make use of this framework. There are many contributors and programmers who share the community. For this reason, using the framework is simpler for development as well as for research.

In other words, they can focus on the logical and creative part of application whereas the tedious task of coding could be handled with ease.

Open Source:

The framework is open source, for which the CakePHP developers do not have to spend any amount in the process of development and have complete access to its source code. It also assists the developers in adding robustness and improves performance in web applications.

Some of the roles of CakePHP developers include

    • Manage development efforts and framework efficiently
    • Support product releases
    • Ability to handle lot of projects in less time
    • Overall review of the quality & progress of the work

CloudLinux’s Recent Integration of PHP 5.5 Alpha 2 Version

Posted on by Jay

Shared hosting operating system provider CloudLinux has expanded their PHP offerings by declaring the availability of PHP 5.5 Alpha2 version to its PHP selector tool.

With the ability to select PHP versions, PHP selector allows the users to get the latest feature updates

and preferred PHP version like PHP 5.2, 5.3, 5.4, and now, 5.5 Alpha2 from their web hosting control panel. CloudLinux places each individual website in a virtual private server.

Each account is then assigned a specific amount of hardware resources and a desirable PHP version, by using the PHP selector tool.

PHP 5.5 Alpha2 version includes new features like the most awaited password hashing API and providing users the ability to use bcrypt along with loop-controlling generators.

Igor Seletskiy the CEO of CloudLinux has expressed that the availability of PHP selector has made it easier to get access to PHP features. He quoted “PHP is possibly the most widely used aspect of any shared web hosting plan.”

Igor Seletskiy also added “Like the rest of the web hosting community, we are excited to start exploring the new features of PHP version 5.5.

However, many hosting companies and their customers would not usually deploy an Alpha version on a large-scale, server-wide basis.

CloudLinux and PHP Selector make it possible for hosting providers to assign individual accounts their own PHP version without affecting other sites on the same hardware.” Integrating such features in CloudLinux has helped PHP development to become easier and more productive

New Secure Password Hashing API In PHP 5.5

Posted on by Jay

The fifth release of PHP, also known as PHP 5.5, was released in this year with great new features and updated standards. One of the most exciting aspects of the update is the Password Hashing API, which aims to provide a universal standard for password hashing functions.

Hashing is a way to store user passwords so that they are not stored in clear text but can still be verified when users log in again. With this new standard, you can use one function (password_hash) to create an account verification token for your user login system. You use another function (password_verify) to validate a hashed password when users sign up or reset their password again.

From the analysis reports, it is now believed that work has officially begun on PHP 5.5. It will be the first major update since the release of the version earlier this year.

In recent years major update releases for PHP were very slow, so it will be interesting to see how fast or slow PHP 5.5 will come into the development process.

Among all the updates in PHP 5.5 the most impressive feature is the new Password Hashing API.

According to some recent security attacks, it is now revealed that a vast majority of PHP developers either don’t understand the password hashing or don’t think it’s worth an effort.

The current implementation of password hashing using crypt() is difficult to implement and work with, but by providing a simple API for password hashing, it will become easier for the developers to simply call the API which will take care of all the issues of the PHP development. Eventually, more projects and developers will be able to use secure password hashing.

It makes sense to include this feature, but let’s just hope for an early official release of this version, so that the PHP developers can take advantage of this security innovation.

Conclusion

The Password Hashing API is a great addition to PHP. It simplifies the process of creating and verifying password hashes. The API is compatible with existing methods and can be used for many different systems, which makes it a useful tool for developers. The Password Hashing API is available in PHP 5.5 and newer versions. This new standard aims to unify the password hashing process and create a universal method to create and verify password hashes.
