Praction with php's generators and generators as methods of class.
Project asks the RSS url, choice of method of parsing. There are two methods:
- With generators
- Without generators
Project outputs the result of parsing, it is an array of ArrayObject's objects of each items of RSS xml data. Handling starts from reading strings of the remote xml-file. If found , starts read strings while will not be found . In case of method with generators first of all works parse generator, and then itemHandler generator. In case of method without generators when found strings are written to buffer array. In this case script eats more memory as compared with another method. Project outputs the number of bytes was used.
- Clone the project.
- Run:
docker-compose up -d
- visit: http://localhost
- With generators:
