Issue

I was trying to connect to SQLite database file using PDO but it is showing the following error message.

PHP Fatal error: Uncaught PDOException: could not find driver in ...

Solution

The cause was that the SQLite extension was not activated. To resolve this, I edited php.ini to change

;extension=pdo_sqlite

to

extension=C:\xuan\bin\php-7.3.8-Win32-VC15-x86\ext\php_pdo_sqlite.dll

From phpinfo(), you should get a section that look like the following.
