Comment:

 In [changeset:"56815" 56815]:
 {{{
 #!CommitTicketReference repository="" revision="56815"
 Query: Ensure that the `page` parameter is scalar in
 `WP_Query::get_posts()`.

 The `page` query var only accepts a scalar value and passes the value
 through functions that assume a scalar value.

 Adding an extra guard condition does not affect its functionality but does
 avoid a PHP fatal error for `trim()` when a non-scalar value such as an
 array is passed.

 Follow-up to [2535], [53891].

 Props brookedot, rlmc, mukesh27, SergeyBiryukov.
 Fixes #56558.
