CakePHP 4 Installation

To create a CakePHP project, run this command into your shell or terminal. Make sure composer should be installed in your system.

$ composer create-project --prefer-dist cakephp/app:~4.0 mycakephp

Above command will creates a project with the name called mycakephp.

Database Connection

Open app_local.php file from /config folder. Search for Datasources. Go to default array of it.

You can add your connection details here to connect with your database. It will be like this –


'Datasources' => [
        'default' => [
            'host' => 'localhost',
             * CakePHP will use the default DB port based on the driver selected
             * MySQL on MAMP uses port 8889, MAMP users will want to uncomment
             * the following line and set the port accordingly
            //'port' => 'non_standard_port_number',

            'username' => 'root',
            'password' => 'sample@123',

            'database' => 'mydatabase',
             * If not using the default 'public' schema with the PostgreSQL driver
             * set it here.
            //'schema' => 'myapp',

             * You can use a DSN string to set the entire configuration
            'url' => env('DATABASE_URL', null),


You can pass host, username, password and database.

Successfully, you are now connected with the database.

There are two types of status flags in migrations.

“up” status means migration migrated and will be available in phinxlog table. “down” status means migration rollback and table removed from database.

$status = $migrations->status();

$migrate = $migrations->rollback();
