HofUniversityCanteenAPI is a small functional libary for accessing and filtering the canteen plan of Hof University.
It is written in PHP 7.3 and above. HofUniversityCanteenAPI is not supported nor endorsed by Studentenwerk Oberfranken or Hochschule Hof.

    Week "1" -- "n" Day
    Day "1" -- "n" Dish

    class Week{
      +array days
    }

    class Day{
      +string name
      +DateTime date
      +array mainCourses
      +array sideDishes
      +array desserts
      +array salads
    }

    class Dish{
      +string name
      +array attributes
      +double collegeStudentPrice
    }      

Just copy the "HofUniversityCanteenAPI"-folder in your project and import the the used functions:

include "HofUniversityCanteenAPI/Helper.php";
use function HofUniversityCanteenAPI\convertAllUnconvertedDataToWeek;
use function HofUniversityCanteenAPI\convertWeekToFormatedGermanString;
use function HofUniversityCanteenAPI\downloadAllUnconvertedData;
use function HofUniversityCanteenAPI\filterWeekByAttributeIdsAndDayNumber;

You can use the following self-explanatory functions:

• getAttributeIdsTable():array
  
• downloadAllUnconvertedData(dayNumber:int, monthNumber:int):SimpleXMLElement
  
• convertAllUnconvertedDataToWeek(allUnconvertedData:SimpleXMLElement):Week
  
• filterWeekByAttributeIdsAndDayNumber(week:Week, attributeIds:array, dayNumber:int):Week
  
• convertWeekToFormatedGermanString(week:Week):string
  
  

The library was tested manually. I could not find any bugs, but there still may be some.

You can find a realistic example here.
