laravel 7 using sqlite give could not find driver (SQL: PRAGMA foreign_keys = ON;)

[Houssam Eddine]

I'm using laravel 7 with sqlite database, I downloaded phpdesktop and change the php version to 7.2.3 nts, and then in the php.ini file i uncomment pdo_sqlite, pdo_mysql and even sqlite3 extensions, but when I run the php desktop chrome file i get this error:  could not find driver (SQL: PRAGMA foreign_keys = ON;)  and this means that sqlite is not active, I tried to change the extension_dir to "./ext", "ext", "absolute_path/ext" but nothing works for me, any ideas please?

SQLite should be enabled by default in the official release. Something must went wrong when upgrading PHP. Compare your PHP/ directory files and the PHP.ini file with the originals.
