Phalcon parser uses same technology as SQLite. The result of any search query as per condition will be displayed as in the screenshot. Database migration helps in transferring data between the specified storage types. To receive the passwords from the user and decrypt it in a particular form, the following code snippet is used. For implementing Oracle database connection in Phalcon, the configuration should be extended with Phalcon\Db\Adapter\Pdo\Oracle abstract class. After creation of the database, the database will be listed as shown in the following screenshot. Phalcon forms are integrated with the validation component to offer instant validation. All text inside them is just ignored in the final output. Model View Controller (MVC) is a software design and structural pattern for developing webbased applications. Phalcon is an open source framework quite popular among developers. Consider for the project which we created in the previous chapter. This sub-folder consists of all the files associated with data migration, which can also be used in any other framework. These messages are used by view to display as appropriate responses. For implementing SQLite connection, the configuration should be extended with Phalcon\Db\Adapter\Pdo\Sqlite abstract class. Phalcon is developed by Andres Gutierrez and his group of collaborators. This is achieved with the help of Object Document Mapper (ODM) for NoSQL database and Object Relational Mapper (ORM) for SQL database. Basically, services.php file inside the config folder acts as a container of all services. Continuing the explanation of INVO, we now address the creation of CRUDs, a very common task that Phalcon will facilitate you using forms, validations, paginators and more. Consider the example of Blog-tutorial, which we created in the previous chapters. Laravel supports all relational databases. Step 1 − Create a project named blog-tutorial. It is important to redirect to the appropriate project path. If encryption is not used, all the internal application will be exposed to the attacker. Other folders outside the web root directory are considered out of reach for the web server and for Phalcon project. Phalcon Query Language (PHQL) It allows user to implement query language similar to SQL query language. The up() method is used for performing migration while the down method rolls back the operation. Step 6 − The dll files and Phalcon tools together help in creating the project/web application.

Phalcon has an asset manager which helps to manage all the asset components like CSS or JS files. Later, the function getMessageTranslation is being called which returns the desired output. Developer Tools with CRUD features are used for developing web applications. The session ID is paired every time with the internal database such that all stored variables are retrieved. In this chapter, we continue explaining how INVO is structured, we’ll talk about the implementation of authentication, authorization using events and plugins and an access control list (ACL) managed by Phalcon. Note − It is important to use session adapter while sending tokens of form, as all the data will be maintained in the session. Phalcon - Switching Databases - We have used a MySQL database in our application. Here is a list of some of the prominent features of Phalcon query language −. View fetches data from its model. Also, C in combination with Phalcon provides Object Relational Mapping (ORM) which provides consistency with models created.
