Database Abstraction Layer

AnyDataset-DB provides a relational database abstraction layer. It is part of the Anydataset project, an agnostic data source abstraction layer for PHP.

Learn more about Anydataset here.

Features

• Connection based on URI
• Handles compatibility and code optimization across multiple databases (e.g., MySQL, PostgreSQL, MS SQL Server)
• Built-in Query Cache support using a PSR-16 compliant interface
• Enables connection routing based on regular expressions for queries (e.g., directing queries to different databases for specific tables)

Connection Based on URI

Database connections are defined using URL-based connection strings.

Supported drivers are listed below:

Database	Connection String	Factory Method
SQLite	sqlite:///path/to/file	getDbInstance()
MySQL/MariaDB	mysql://username:password@hostname:port/database	getDbInstance()
PostgreSQL	psql://username:password@hostname:port/database	getDbInstance()
SQL Server (DbLib)	dblib://username:password@hostname:port/database	getDbInstance()
SQL Server (Sqlsrv)	sqlsrv://username:password@hostname:port/database	getDbInstance()
Oracle (OCI8)	oci8://username:password@hostname:port/database	getDbInstance()
Generic PDO	pdo://username:password@pdo_driver?PDO_PARAMETERS	getDbInstance()

Example usage:

<?php
$conn = \ByJG\AnyDataset\Db\Factory::getDbInstance("mysql://root:password@10.0.1.10/myschema");
