What are the performance implications of reading PHP code from a database compared to including it from a file?

Reading PHP code from a database can have performance implications compared to including it from a file because it requires additional database queries and processing time. This can lead to slower page load times and increased server load. To improve performance, it is recommended to store PHP code in files and include them using PHP's include or require functions.

// Include PHP code from a file
include 'path/to/file.php';
