While I know what is an api and rest api and … I always have a stupid question in my mind that why Yii or laravel reference use API in their headers? http://www.yiiframework.com/doc-2.0/
What does API mean in this context?
API stands for Application Programming Interface. A web service has an API for whom wants to use it. And an web framewrok like Yii also has it for whom wants to use it.
