I have multiple multidimensional arrays that each have the same structure with different lengths.
arr1 = [["23 Jan",3],["29 Jan",10],["19 Jan",23],["25 Jan",23]]
arr2 = [["31 Jan",7],["29 Jan",12],["01 Feb",4]]
My result would be a merged array without duplicate dates ordered by the date. For ...

This is certainly a solution what you could use.
Another solution might be :
<tabpanel id="stbvc" disabled="true">
We start with that tab disabled.
As the subscriber is created you can set the disabled to false and set the source of the include, so the tab will unlock.
Another option, what I...

I wrote this CRUD class in PHP that has methods to do database interactions, but I want to know if it is good/secure/elegant?
It works fine and all and it hasn't ever given me any troubles, but I'm really trying to improve my coding habits, so any feedback would be great!

I got help with some Matlab code for a problem in numerical analysis. I find it difficult to understand though. Now I can make 2 plots. I don't fully understand what the code does.
The first part of the code is
