How to write to the database one by one?

Question

PHP

Hello!

How to write to the database one by one?
Well, for example, there is a script.php controller, which is accessed through the site a large number of times. How to make the order of writing to the database so that if a person now accesses the script, then a record with the number 1 goes to the database, the next person accesses the script, then a record with the number 0 goes to the database, etc., either 1 or 0.
How all this to define and write down? if several people can access the script at once.

Thanks

The database has an autoincrement field type, more precisely, it is an attribute for an index field. Any insertion increments it by 1 . use it
