• ePub 3 support added

  3 novembre 2013, par Grandt

  ePub 3 support added
  * Added : ePub 3 support. The ePub 3 still contains the NCX for backwards
  
  combatability to ePub 2 readers, though there is no gurantee that it'll
  
  work on all readers.
  
  *  The EPub class constructor now takes arguments for epub version,
  
  EPub::BOOK_VERSION_EPUB2 or EPub::BOOK_VERSION_EPUB3
  
  *  The other new parameters on the EPub constructor are for default
  
  language and writing direction, used on the generated ePub 3 TOC.
  
  * Added : Ability to reference sub chapter id's
  
  *  ->addChapter($chapterName, $chapterLink) ; where the link must contain
  
  the #id.
  

• Memcached protocol support

  15 novembre 2013, par Mikko Koppanen — Imagick

  For the past few days I’ve been adding Memcached binary protocol support to PECL memcached extension. The protocol handler provides a high-level abstraction for acting as a memcached server. There are quite a few things still missing and only binary protocol is supported at the moment, but the code seems to work reasonably well in small-scale testing.

  I am not sure whether this is useful for anyone, but at least it allows things such as quick prototyping of network servers, exposing sqlite database over memcached protocol etc.

  The code is quite simple and implementing a simple server responding to get and set would look roughly like the following :

  php

  < view plain text >

  1. < ?php
  2. // Create new server instance
  3. $server = new MemcachedServer() ;
  4.  
  5. // Create a simple storage class
  6. class Storage {
  7.   private $values = array () ;
  8.   
  9.   public function set ($key, $value, $expiration) {
  10.     $this->values [$key] = array (’value’ => $value,
  11.                    ’expires’ => time () + $expiration) ;
  12.   }
  13.  
  14.   public function get ($key) {
  15.     if (isset ($this->values [$key])) {
  16.       if ($this->values [$key] [’expires’] < time ()) {
  17.         unset ($this->values [$key]) ;
  18.         return null ;
  19.       }
  20.       return $this->values [$key] [’value’] ;
  21.     }
  22.     else
  23.       return null ;
  24.   }
  25. }
  26.  
  27. $storage = new Storage () ;
  28.  
  29. // Set callback for get command
  30. $server->on (Memcached: :ON_GET,
  31.        function ($client_id, $key, &$value, &$flags, &$cas) use ($storage) {
  32.          echo "Getting key=[$key]" . PHP_EOL ;
  33.          if (($value = $storage->get ($key))  != null)
  34.            return Memcached: :RESPONSE_SUCCESS ;
  35.  
  36.          return Memcached: :RESPONSE_KEY_ENOENT ;
  37.        }) ;
  38.  
  39. // Set callback for set command
  40. $server->on (Memcached: :ON_SET,
  41.        function ($client_id, $key, $value, $flags, $expiration, $cas, &$result_cas) use ($storage) {
  42.          echo "Setting key=[$key] value=[$value]" . PHP_EOL ;
  43.          $storage->set ($key, $value, $expiration) ;
  44.          return Memcached: :RESPONSE_SUCCESS ;
  45.        }) ;
  46.  
  47. // Run the server on localhost, port 3434. Will block
  48. $server->run ("127.0.0.1:3434") ;
  49.  ?>

  And the client that communicates with the server :

  php

  < view plain text >

  1. < ?php
  2.  
  3. $cache = new Memcached() ;
  4. $cache->setOption(Memcached: :OPT_BINARY_PROTOCOL, true) ;
  5. $cache->setOption(Memcached: :OPT_COMPRESSION, false) ;
  6. $cache->addServer(’localhost’, 3434) ;
  7.  
  8. $cache->set (’set_key1’, ’This is the first key’, 10) ;
  9. var_dump ($cache->get (’set_key1’)) ;
  10.  
  11. $cache->set (’set_key2’, ’This is the second key’, 2) ;
  12. var_dump ($cache->get (’set_key2’)) ;
  13.  ?>

  The code is still work in progress but it’s available in github : https://github.com/mkoppanen/php-memcached/tree/feature-server. Note that you need to compile libmemcached with –enable-libmemcachedprotocol and the PECL memcached extension with –enable-memcached-protocol.
