This one, you have to pay attention to two points:

1. Data validation before storage, keep in mind that all user input content is not trustworthy. Remember!!!

2. Visually you want to display this content on the page, you can't show it directly ... What you have to show to the user is the MD converted to HTML format in order to be friendly! Oh, yes.

In view of the above two points: can go to a website: https://packagist.org/

Search markdown : You will find a lot of wheels ~ Of course, you have to use composer ~ What? You said you didn't use this? Why isn't?

• With a markdown parser, the top of the page shows the markdown format of the edge display has been resolved

• Save two when you save a database

• Remove the saved markdown when you need to update

• Output the saved HTML directly when you want to see it
