Yii is a web programming framework used to develop all kinds of web applications using PHP. It is suitable to develop large scale application such as e-commerce projects, CMS, portals, forums etc.
Major enhancement
Currently Yii has two major versions: 1.1 and 2.0 RC. The 1.1 version is currently in maintenance mode. Version 2.0 is a rewrite of Yii and it has adopted the latest technologies and protocols. Version 2.0 represents the current generation of the framework and will receive main development over the next few years. Some important changes made in the new release have been given below.
Security
Many security experts have reviewed Yii code, leaving behind significant feedback about how the security of Yii can be improved. Some security codes are rewritten to provide the best encryption and key elements and protect them from timing issues. The earlier security helper class has been modified into security application components. Apart from that, other minor changes have done in order to enhance the security issues.
Database
Replication of Database and splitting of read and write
Now Yii has its own support for read-write splitting and database replication. Database replication serves to replicate from a master server to a slave server. All updates and writes are held on master server and read is conducted on slave servers.
Transactions
You will find lots of enhancements related to using DB transaction. First, you are employed with a transaction in call back style. Secondly, few of them are activated for transaction and at last, you have to set the transaction isolation level in the beginning of a new transaction.
Building Query conditions
In order to develop a query, arbitrary operators are used and Yii will correctly quote the name of the column and using parameters you can handle the value.
Asset Management
It uses the Composer Asset Plugin to handle the dependencies involved NPM packages and Power. Due to this change, you just have to first perform the installation of the plugin and then run the command before you upgrade to the latest version of Yii.
Logging and Error Handling
Now you can use arrays or objects as log messages and the default log target will convert them into text display automatically.
Development Tools
In the latest version, the debugger panel has been included in shows the loaded asset bundles and content. Previously it provided a web interface and now, you just have to create a new Gii generator which can be used in console and web modes.
