Persistence in PHP with Doctrine ORM

Bootstrapping the app

The following steps need to be performed for bootstrapping the app:

1. Create a new file called config/config.php that will contain configuration parameters of our app as shown in the following code:

     <?php
   
     // App configuration
     $dbParams = [
       'driver' => 'pdo_sqlite',
       'path' => __DIR__.'/../data/blog.db'
     ];
   
     // Dev mode?
     $dev = true;

   The Doctrine configuration parameters are stored in the $dbParams array. We will use a SQLite Database called blog.db stored in the data/ directory. If you want to use MySQL or any other DBMS, it's here that you will configure the driver to use, the database name, and the access credentials.

   Note

   The following is a sample configuration to use MySQL instead of SQLite:

   $dbParams = [ 'driver' => 'pdo_mysql', ...
