------------------------------+-----------------------------
`str_contains()` was introduced in PHP 8.0 to perform a case-sensitive
check indicating if the string to search in (haystack) contains the given
substring (needle).
WordPress core includes a polyfill for `str_contains()` on PHP < 8.0 as of
WordPress 5.9.
This change replaces new introduced `false !== strpos( ... )` and `false
=== strpos( ... )` with `str_contains()` in core files, making the code
more readable and consistent, as well as better aligned with modern
development practices.
Introduced in [[https://core.trac.wordpress.org/changeset/60269|r60269]]
and [[https://core.trac.wordpress.org/changeset/60939|60939]]
