Code snippets

You will find here 63 code snippets I find useful so I don't have to Google ™ or Stackoverflow ™ them when I need. There are also code snippets I always forget! 😁 Sometimes, related links to the code will be available. The main difference with other random snippets you will find on the web is that in most cases (for the Symfony related ones) you will be able to run them directly from this website to check the output so you can verify it works as expected ™.
