Loading collection data...
Collections are a way for you to organize kata so that you can create your own training routines. Every collection you create is public and automatically sharable with other warriors. After you have added a few kata to a collection you and others can train on the kata contained within the collection.

sorry can you explain what did you do before substr
My dumbass forgot that substr existed, and I went with indexing and concatenating after deep copying. I thought that'd be a performance drain but actually it's very well optimised and it came to ~0.1ms faster than substringing; was quite interesting.
php much
that's great
fret not, it happens to the best of us
Some spacing would be good, to increase readability.
