You need to validate and sanitize data in your PHP script. How would you do this?

To validate and sanitize data in PHP, you can use the filter_var() function. This function provides a range of predefined filters to validate and sanitize different types of data, such as URLs, email addresses, numbers, and more. By applying appropriate filters, the filter_var() function helps ensure the integrity, security, and cleanliness of the data.
