#28170 closed enhancement (fixed)

Add utility method for casting a var to boolean

Description

Because PHP can be configured without --filter, it is not 100% safe to use filter_var(). This is problematic for casting "false" to false, as PHP always casts it to true. FILTER_VALIDATE_BOOLEAN fixes this, but it may not be available.

Proposed new function: wp_validate_boolean().

Add a new function, wp_validate_boolean(), to replace filter_var( $var, FILTER_VALIDATE_BOOLEAN ).

Fixes #28170.
