What is the billing that does not require a database?

Question

Billing systems

Hello everyone, I wanted to know - is there a free billing written in PHP that does not use databases, but files?

The bottom line is that there are problems with databases, for example MySQL, but I don’t like using databases at all, but only standard files, and is there one that can have the same functionality as many popular billings, such as tickets, order and payment, and if there is one, please give a link to the site where you can download it

Well, take Mysql and so on as files. They are files by the way.
And all the dances with storing information in ordinary text files (which can still be called a database) will eventually come down to the fact that you will need to implement many functions (blocking, transactions, etc., for billing, there are still increased requirements for reliability, protection from dubbing, etc.) of already existing databases. wondering why is this needed?
If you don’t like working with mysql, don’t work, php itself has had pdo for a long time, moreover, there are various higher-level abstractions like Doctrine 2 or Active Record (for example, Eloquent)
where you practically don’t need to think about specifics.
