[Solid PHP Basics] PHP array, string view, solid view

I haven't written a blog for a long time. I'm busy with it, so I have to continue without having to talk about it.

 

When I was working on a project today, I encountered a situation where the array needs to be processed and the key name needs to be retained. Here I wrote it:

1. array merging array_merage () will reset the key name arrar1 + array2 will retain the original key name 2. when the array is partitioned, arrar_slice () resets the key name array_slice ($ dealDatas, $ start, $ length, true). If the 4th parameters are true, the key name is retained.
