Experiment with sorting after query limit

So this is my first question here, please forgive me if something is wrong. I'm trying to make a sort query based on constraints. So there is a Customers table with 90 records.

CSS Grid: Create new row when child content overflows column width

Shortest way to convert all PHP types to string

I'm writing a general system that I hope can one day be applied to fields like medicine (i.e. it's "scientific"). I think the best way is to represent all the data in php with strings (true will be "true", false will be "false" and so on). The reason for this is that in php any value has a unique string representation (such as the php code itself). I post this question to speed up the design process of this program. Some values are easily converted to strings: numbers, booleans, etc. Some are not easy: objects, arrays, resources. I think the transfer object and

What are not the characteristics of mobile Internet

Course Introduction：The characteristics of mobile Internet are not "transparency" and "weak correlation between business and network". The mobile Internet has "high privacy" and "strong relevance". Due to the characteristics of mobility and portability, the mobile Internet has a higher degree of information protection; mobile Internet users do not need to share information on their devices, thus ensuring the privacy of the mobile Internet. Since mobile Internet services are limited by network and terminal capabilities, their service content and form also need to match specific network technical specifications and terminal types, with strong correlation.
