1. Service Controller Example
2. Service CRUD Package

Use the Service controller to create web services. Puko directly returns the data in JSON format, allowing you to instantly scaffold your service using the php puko routes service add command. Query the data and return it at the end of your controller function.

The key difference is in the class extension:

class students extends Service {}

A Service controller extends the Service class, rather than the View class used for processing HTML files.

Service Controller Example

public function students() {
    // Application logic here
    // Database operations can be performed here too

    return [
        'Identification' => 'ID120027103',
        'Name' => 'Didit Velliz',
        'Age' => 26,
        'Skills' => [
            'PHP', 'MySQL'
        ]
    ];
}

The data returned from the controller will be represented as JSON:

{
    "Identification": "ID120027103",
    "Name": "Didit Velliz",
    "Age": 26,
    "Skills": [
      "PHP",
      "MySQL"
    ]
}

Dynamic Parameters: Dynamic data retrieved from URL parameters is supported using the {?} keyword during route creation.

Service CRUD Package

The Service controller also supports generating multiple endpoints with a single command using the CRUD package. Use the following pukoconsole command:

php puko routes service crud [schema]/[table]

• Schema: Refers to the database configuration (defaults to primary).
• Table: Refers to the table name in the database.

Example: php puko routes service crud primary/students

This command generates a controller located at controller/primary/students.php with complete CRUD functions. Controller code and routes are automatically configured.
