What are the common types of errors encountered in CodeIgniter applications?

CodeIgniter errors can broadly be categorized into: 1) **Syntax Errors:** These occur due to incorrect code syntax, like typos or missing semicolons. 2) **Runtime Errors:** These happen during program execution, such as division by zero, undefined variables, or attempting to access a non-existent file. 3) **Database Errors:** These relate to issues with the database connection, queries, or data integrity. 4) **Logic Errors:** These are the trickiest – the code runs without crashing, but produces incorrect results due to flawed logic.
