PHP DSN #ARCHIVED#
==================

[](#php-dsn-archived)

A utility for parsing and generating service DSNs

What is a DSN?
--------------

[](#what-is-a-dsn)

A [data source name](http://en.wikipedia.org/wiki/Data_source_name) (DSN) is a string which defines how to connect to a service. Since it's a string, it's portable, not language or implementation dependent and anything capable of parsing it can know how to connect to the service it points at.

What does this repo do?
-----------------------

[](#what-does-this-repo-do)

This repo only provides a means of converting a DSN string into an array and vice versa.

Wrapper classes?
----------------

[](#wrapper-classes)

When using a wrapper class, this repo provides an array *in the format expected* by a particular consumer. So for example, the CakePHP wrapper classes provide arrays in the format the framework understands for a given DSN string.

Basic usage
-----------

[](#basic-usage)

The main dsn class implements a parse function which returns a dsn instance:

```
use \AD7six\Dsn\Dsn;

$url = $_ENV['SOME_SERVICE_URL'];
$dsn = Dsn::parse($url);

```

The class of the returned object is dependent upon the scheme of the service url, for example:

```
// $dsn is an instance of \AD7six\Dsn\Db\MysqlDsn;
$dsn = Dsn::parse('mysql://host/dbname');

// $dsn is an instance of \AD7six\Dsn\Db\SqliteDsn;
$dsn = Dsn::parse('sqlite:///path/to/name.db');

```

For unknown schemes - the an instance of the called class is returned. This also means that a more specific instance can be obtained by using a less-generic class where appropriate:

```
// $dsn is an instance of \AD7six\Dsn\Dsn;
$dsn = Dsn::parse('newdb://host/dbname');

// $dsn is an instance of \AD7six\Dsn\DbDsn;
$dsn = DbDsn::parse('newdb://host/dbname');

```

In all of the above cases, the returned instance is the "raw" dsn data:

```
// $dsn is an instance of \AD7six\Dsn\Db\MysqlDsn;
$dsn = Dsn::parse('mysql://host/dbname');

$dsn->toArray();
[
	'scheme' => 'mysql',
	'host' => 'host',
	'port' => 3306,
	'database' => 'dbname'
]

```

If the behavior of the raw dsn needs to be modified - use a wrapper implementation
