Supporting Enqueue
Enqueue is an MIT-licensed open source project with its ongoing development made possible entirely by the support of community and our customers. If you’d like to join them, please consider:
DSN Parser.
The enqueue/dsn tool helps to parse DSN\URI string. The tool is used by Enqueue transports to parse DSNs.
Installation
composer req enqueue/dsn 0.9.x
Examples
Basic usage:
<?php
use Enqueue\Dsn\Dsn;
$dsn = Dsn::parseFirst('mysql+pdo://user:password@localhost:3306/database?connection_timeout=123');
$dsn->getSchemeProtocol(); // 'mysql'
$dsn->getScheme(); // 'mysql+pdo'
$dsn->getSchemeExtensions(); // ['pdo']
$dsn->getUser(); // 'user'
$dsn->getPassword(); // 'password'
$dsn->getHost(); // 'localhost'
$dsn->getPort(); // 3306
$dsn->getQueryString(); // 'connection_timeout=123'
$dsn->getQuery(); // ['connection_timeout' => '123']
$dsn->getString('connection_timeout'); // '123'
$dsn->getDecimal('connection_timeout'); // 123
Parse Cluster DSN:
<?php
use Enqueue\Dsn\Dsn;
$dsns = Dsn::parse('mysql+pdo://user:password@foo:3306,bar:5678/database?connection_timeout=123');
count($dsns); // 2
$dsns[0]->getUser(); // 'user'
$dsns[0]->getPassword(); // 'password'
$dsns[0]->getHost(); // 'foo'
$dsns[0]->getPort(); // 3306
$dsns[1]->getUser(); // 'user'
$dsns[1]->getPassword(); // 'password'
$dsns[1]->getHost(); // 'bar'
$dsns[1]->getPort(); // 5678
Some parts could be omitted:
<?php
use Enqueue\Dsn\Dsn;
$dsn = Dsn::parseFirst('sqs:?key=aKey&secret=aSecret&token=aToken');
$dsn->getSchemeProtocol(); // 'sqs'
$dsn->getScheme(); // 'sqs'
$dsn->getSchemeExtensions(); // []
$dsn->getUser(); // null
$dsn->getPassword(); // null
$dsn->getHost(); // null
$dsn->getPort(); // null
$dsn->getString('key'); // 'aKey'
$dsn->getString('secret'); // 'aSecret'
Get typed query params:
<?php
use Enqueue\Dsn\Dsn;
$dsn = Dsn::parseFirst('sqs:?decimal=12&octal=0666&float=1.2&bool=1&array[0]=val&array[1]=123');
$dsn->getDecimal('decimal'); // 12
$dsn->getOctal('decimal'); // 0666
$dsn->getFloat('float'); // 1.2
$dsn->getBool('bool'); // true
$dsn->getArray('array')->getString(0); // val
$dsn->getArray('array')->getDecimal(1); // 123
$dsn->getArray('array')->toArray(); // [val]
Throws exception if DSN not valid:
<?php
use Enqueue\Dsn\Dsn;
$dsn = Dsn::parseFirst('foo'); // throws exception here
Throws exception if cannot cast query parameter:
<?php
use Enqueue\Dsn\Dsn;
$dsn = Dsn::parseFirst('mysql:?connection_timeout=notInt');
$dsn->getDecimal('connection_timeout'); // throws exception here
