Setup PHP-CRUD-API with a PHPMaker Project

Here's a quick tutorial on how to include REST API documentation into your PHPMaker Project.

1. Generate your PHPMaker project into a folder e.g. C:\wamp64\www\datamart\docs
2. Create a folder in the root called api e.g. C:\wamp64\www\datamart\docs\api
3. Copy and Paste the api.php code and the index.html code into the folder
4. Find the configuration part of code at the bottom of the api.php and configure it to your needs. The configuration part of code should look like the section of code below:

 $config = new Config([
        // 'driver' => //$CONFIG["CONNECTION_INFO"]["DB"]["type"],
        // 'address' => //$CONFIG["CONNECTION_INFO"]["DB"]["host"],
        // 'port' => //$CONFIG["CONNECTION_INFO"]["DB"]["port"],
        'username' => $CONFIG["CONNECTION_INFO"]["DB"]["user"], //'root',
        'password' => $CONFIG["CONNECTION_INFO"]["DB"]["pass"],
        'database' => $CONFIG["CONNECTION_INFO"]["DB"]["db"],
        "controllers"   => 'records,openapi',
        'openApiBase'   => '{"info":{"title":"Data Catalog API","version":"1.0.0"}}',
        'middlewares' => 'authorization',
        'authorization.tableHandler' => function ($operation, $tableName) {
            return (in_array($operation, array('list','read','document')));  // The API will read and list records only
        }
        // 'debug' => false
    ]);

5. Go to the link URL where the api folder is located to view the Open API 3.0 documentation e.g. https://localhost/datamart/docs/api, you should see the swagger documentation

api.php
