In use Before SQLite, make sure that sqlite and pdo configuration have been enabled in php.ini

Open the PHP.INI file and add the following extension:
extension=php_pdo.dll

extension=php_pdo_sqlite.dll
extension=php_sqlite.dll
The sqlite_open command opens a database file.
Create the file if it does not exist.

sqlite_query can execute SQL statements.
Create a table and insert data.

sqlite_unbuffered_query issues a SELECT statement.
Loop and display the results.
