What is the purpose of deleting the output in PHP?

Deleting the output in PHP can be useful when you want to prevent sensitive information from being displayed to the user, such as error messages or debugging information. This can help improve the security of your application by not revealing potentially harmful details to attackers. To delete the output in PHP, you can use the ob_clean() function to clear the output buffer.

// Clear the output buffer to delete any output
ob_clean();
