A set of tools to simplify the work of creating backend APIs for your frontend projects. Includes tutorials, patterns and practical examples for creating projects based on REST APIs.
## Installation
Download source code and add to your project
```php
<?php
require_once __DIR__ . '/APIlite/src/APIlite.php';
```
or use composer
```bash
composer require tpsoft/apilite
```
and add to your project
```php
<?php
require __DIR__ . '/vendor/autoload.php';
class YourAPI extends \TPsoft\APIlite\APIlite {
/**
* My first method for greetings.
*
* @param string $name Your name
* @param int $age Your age
* @return string Greetings
*/
public function myFirstMethod(string $name, int $age): string
{
return 'Hi, I`m '.$name.' and I`m '.$age.' years old.';
}
}
```
