cakephp2-php8/libs/dbo_sqlite.php
pies 3f10d747b7 - Cake didn't work without mod_rewrite, fixed (/index.php, /libs/router.php).
- Controller accepts $params as a constructor parameter (for Larry).
- DBO::prepare() returned an array even when a string was passed to it, fixed.
- Flay and Folder tests fixed, DBO_Factory test disabled (no database config by default, so do database access to test).
-
