Is Wrapping intval() Around esc_attr() Redundant for Escaping Input?

Based on WordPress documentation for esc_attr function, it is returning a string value. So, If you need to have the integer value, you need using intval function. But, when you want to display that value or put it as part of markup, it doesn’t make sense.

Escape functions are useful for outputting and printing values. If you want to save a value in the database, the data type is a matter and you may need to use intval function alongside sanitization.
