How to decrease the memory usage in codeigniter?

There are several ways to decrease memory usage in CodeIgniter:

1. Use fewer database queries: Try to minimize the number of database queries in your application by optimizing your database queries and using techniques like eager loading and caching.
2. Use pagination: When fetching a large number of records from the database, consider implementing pagination so that only a subset of the data is loaded at a time.
3. Optimize your code: Review your code and look for any inefficiencies or redundant operations that can be optimized or eliminated to reduce memory usage.
4. Use caching: Implement caching mechanisms to store and retrieve data that is frequently accessed, reducing the need to fetch data from the database repeatedly.
5. Use compression: Enable compression for your assets such as images, CSS, and JavaScript files to reduce the amount of memory needed to load these resources.
6. Upgrade your server: If the memory usage is still high after optimizing your code, consider upgrading your server to a plan with more memory capacity to handle the increased load.

By implementing these strategies, you can effectively decrease memory usage in your CodeIgniter application and improve its performance.
