I have this class that exposes var_dump data in order to get better human readable layout.
I have done it with a lot of preg_replace and a series of regular expressions that run one after another on the result of the var_dump to have a more readable and highlighted output.
I would like them to re...

I am not good at programming, but I heard that the if function is in Python. In terms of performance, the script works very poorly and very slowly.
