What are the potential pitfalls of converting mysql functions to mysqli functions in PHP?

When converting mysql functions to mysqli functions in PHP, potential pitfalls include changes in function names and parameter order, as well as differences in error handling and connection management. To solve this issue, carefully review the documentation for mysqli functions and make the necessary adjustments to your code.
