How can the error message "Invalid locale category name LC_MESSAGES" be resolved when using setlocale in PHP?

The error message "Invalid locale category name LC_MESSAGES" occurs when an incorrect locale category name is used with the setlocale function in PHP. To resolve this issue, you need to ensure that the correct locale category names are used. In this case, the correct locale category name for messages is LC_MESSAGES, not just MESSAGES.

// Correct usage of setlocale with LC_MESSAGES category
setlocale(LC_MESSAGES, 'en_US.UTF-8');
