README

This project is a PostgreSQL version of ThingEngineer's MysqliDb Class, that supports the basic functionality and syntax provided by said class, tailored specifically to PostgreSQL.

Installation

This class requires PHP 5.4+ or 7+ to work. You can either place the src/PostgresDb.php in your project and require/include it, or use Composer (strongly recommended)

composer require seinopsys/postgresql-database-class:^3.0

Usage

$db = new \SeinopSys\PostgresDb($database_name, $host, $username, $password);

For a more in-depth guide see USAGE.md

Upgrading from 2.x

1. Removed deprecated methods

   These methods were deprecated in version 2.x and have been removed in 3.x. Use the renamed variants as indicated below:

   2.x	3.x
   $db->rawQuery(…);	$db->query(…);
   $db->rawQuerySingle(…);	$db->querySingle(…);
   $db->pdo();	$db->getConnection();

2. Namespace change

   As of 3.x - to comply fully with the PSR-2 coding standard - the class now resides in the SeinopSys namespace. Here's a handy table to show what you need to change and how:

   2.x	3.x
   $db = new PostgresDb(…);	$db = new \SeinopSys\PostgresDb(…);
   $db = new \PostgresDb(…);	$db = new \SeinopSys\PostgresDb(…);
   use \PostgresDb; $db = new PostgresDb(…);	use \SeinopSys\PostgresDb; $db = new PostgresDb(…);

3. Internal code structure changes

   As of 3.x all private/protected methods and properties have dropped the _ prefix, so be sure to update your wrapper class (if you use one).
