Factory utility that creates a PDO object from environment configuration.

• It has not undergone extensive testing.
• Primarily intended for internal projects, subject to potential breaking changes without prior notice.
• There are likely many missing features.

The following environmental variables can be used:

• PDO_FACTORY_ADAPTER specifies which adapter will be used and how the rest of the environmental variables are going to be collected. Default 'mysql'
• ${PDO_FACTORY_ADAPTER}_HOSTNAME default 'localhost'
• ${PDO_FACTORY_ADAPTER}_PORT default NULL, fallbacks to the default port of each adapter
• ${PDO_FACTORY_ADAPTER}_USERNAME default NULL
• ${PDO_FACTORY_ADAPTER}_PASSWORD default NULL
• ${PDO_FACTORY_ADAPTER}_DATABASE default NULL
• ${PDO_FACTORY_ADAPTER}_CHARSET default NULL

MySQL specific

• MYSQL_UNIX_SOCKET default NULL. If it exists MYSQL_HOSTNAME and MYSQL_PORT are ommited

Postgres specific

• POSTGRES_SSL_MODE default NULL. See more
