- * LoggerAppenderPDO appender logs to a database using the PHP's PDO extension.
- *
- * ## Configurable parameters: ##
- *
- * - dsn             - The Data Source Name (DSN) used to connect to the database.
- * - user            - Username used to connect to the database.
- * - password        - Password used to connect to the database.
- * - table           - Name of the table to which log entries are be inserted.
- * - insertSQL       - Sets the insert statement for a logging event. Defaults
- *                     to the correct one - change only if you are sure what you are doing.
- * - insertPattern   - The conversion pattern to use in conjuction with insert
- *                     SQL. Must contain the same number of comma separated
- *                     conversion patterns as there are question marks in the
- *                     insertSQL.
