&reftitle.install; The PDO_SQLITE PDO driver is enabled by default. To disable, --without-pdo-sqlite[=DIR] may be used, where the optional [=DIR] is the sqlite base install directory. As of PHP 7.4.0 libsqlite ≥ 3.5.0 is required. Formerly, the bundled libsqlite could have been used instead, and was the default, if [=DIR] has been omitted.
