PHP - Html Transfer Code Hypertext conversion code, there is already a lot of it on the market, but I have been practicing it myself in the past few days~~~~

Supports multiple nesting and same-label nesting, mixed highlighting (There is still a little problem)

I feel that it is easy to modify and expand~~~~~~~~~~~
