What could be causing the issue of text not being entered correctly into the database when the script runs on the internet but not on a local server?

The issue could be related to character encoding differences between the local server and the internet server. To solve this problem, make sure that the character encoding settings are consistent across both servers. Check the database collation settings and ensure they are the same on both servers.

// Set the character encoding for the database connection
mysqli_set_charset($conn, 'utf8');
