<pre style='padding-left: 1em; margin: 2em 0; border-left: 2px solid #ccc; line-height: 1.25; font-size: 105%; font-family: sans-serif'>Database: Replace `str_ends_with()` usage in `wpdb::prepare()`.
This avoids a fatal error if the file is included directly outside of WordPress core, e.g. by HyperDB.
While WordPress core does include a polyfill function, it is not directly loaded in the `wpdb` class.
This commit replaces the `str_ends_with()` calls with `substr_compare()` for now.
