Tagging interfaces

Library provides interfaces that tag and convey similar meaning through many different exceptions.

 

They allow you as a dev to catch a meaning instead of a context.

try {
    $storage->getProducts();
}catch(FileNotFoundException $ex){
    //The file for $storage 
    //engine cannot be found
}
try {
    $storage->getProducts();
}catch(DataNotFoundException $ex){
    //The data for $storage 
    //engine cannot be found
}

Or

Advantages

  • Less painful exception writing
  • Less painful \exception usage
  • Better flexibility and interop

Disadvantages

  • Less precise contexts
  • Still in the PHP user-land

Installing

composer require crazycodr/standard-exceptions

Usage

class HomeController {

    public function index(){
        throw new Exceptions\Operation\NotImplementedException();
    }

}
