Documentation

This library provide:

• a lot of simple identifiers
• a composite identifier
• many formatter

Identifiers

• Machine identifiers
  • HostByNameIdentifier (base on gethostbyname)
  • HostnameIdentifier (base on gethostname)
  • MyPidIdentifier (base on getmypid)
  • PHPOSIdentifier (base on PHP_OS)
  • PHPUnameIdentifier (base on php_uname)
• Configuration identifiers
  • PHPSapiNameIdentifier (base on php_sapi_name)
  • PHPVersionIdentifier (base on php_version)
  • PHPVersionIdIdentifier (base on PHP_VERSION_ID)
• Filesystem identifiers
  • MyGidIdentifier (base on getmygid)
  • MyUidIdentifier (base on getmyuid)
• Unique identifiers
  • SecureRandomStringIdentifier
  • TimeIdentifier (base on time)
  • UniqidIdentifier (base on uniqid)
  • Uuid1Identifier (base on ramsey/uuid V1)
  • Uuid3Identifier (base on ramsey/uuid V3)
  • Uuid4Identifier (base on ramsey/uuid V4)
  • Uuid5Identifier (base on ramsey/uuid V5)
• other
  • StringIdentifier (inject your own string as identifier)
  • CompositeIdentifier (compose with other identifiers)

Formatters

• ImplodeFormatter (base on implode)
• StrReplaceFormatter (base on str_replace)
• VsprintfFormatter (base on vsprintf)

Usage

If you want to identify the machine with the sapi and phpversion and a uniqID

<?php
use Symftony\Identifier\Formatter\VsprintfFormatter;
use Symftony\Identifier\Formatter\StrReplaceFormatter;
use Symftony\Identifier\CompositeIdentifier;
use Symftony\Identifier\HostByNameIdentifier;
use Symftony\Identifier\PHPSapiNameIdentifier;
use Symftony\Identifier\PHPVersionIdentifier;
use Symftony\Identifier\UniqidIdentifier;

$identifier = new CompositeIdentifier(
    new HostByNameIdentifier(),
    new PHPSapiNameIdentifier(),
    new PHPVersionIdentifier(),
    new UniqidIdentifier()
);
// create a format
$format1 = new VsprintfFormatter('%s@%s(php-%s)#%s');
$format2 = new StrReplaceFormatter('{host_by_name}@{php_sapi_name}(php-{php_version})#{uniqid}');

// CompositeIdentifier use ImplodeFormatter by default
echo $identifier;// 192.168.1.12_cli_7.2.5_5b2779e6098ca
echo $identifier->getIdentifier();// 192.168.1.12_cli_7.2.5_5b2779e6098ca
echo $identifier->getIdentifier($format1);// 192.168.1.12@cli(php-7.2.5)#5b2779e6098ca
echo $identifier->getIdentifier($format2);// 192.168.1.12@cli(php-7.2.5)#5b2779e6098ca

Todo

Identifier builder/factory in order to easily create composite identifier with default format. See how to regenerate the identifier that can changed (time/unique ...)
