Concept of Migration in CodeIgniter 4 Tutorial. Migration gives the structure scheme of database table. If we have an application in Codeigniter 4 in which we need database tables, better is to create tables using migrations. By creating manual database tables, it will be difficult for those cases when we switch the application from one server ...
If that's the case, the codeigniter complete transaction method will see that a query failed, and roll back the entire thing. I could alternatively use transactions manually, and keep track manually something failed or succeeded, and if it succeeded on the second try, then commit the transaction, and only rollback otherwise.

hostname − Specify location of your database here e.g. localhost or IP address. username − Set username of your database here. password − Set password of your database here. database − Set name of the database here. dbdriver − Set type of database that you are using e.g. MySQL, MySQLi, Postgre SQL, ODBC, and MS SQL.
In this tutorial, we will learn to convert CodeIgniter query to json and also to insert them in our database. It is difficult to store an array in database which contains a lots of user data. We will have to make a lots of indexes in array in order to store them in database. In such situation, json is very helpful.
As you specify, I need to know if this way is functional even though I do not follow the example as done in Codeigniter, and if using these functions Codeigniter can detect whether or not queries or insertions in the database fail, also if they can give me Some better example.

Notes. By default Codeigniter runs all transactions in Strict Mode. When strict mode is enabled, if you are running multiple groups of transactions, if one group fails all groups will be rolled back.If strict mode is disabled, each group is treated independently, meaning a failure of one group will not affect any others.; What I tried was more of a trick, but it worked for me.
