First, and most important: a lot of stability and consistency fixes (previous release wasn’t . . . → Read More: Syck 0.9.2]]> I’ve just released syck for php 0.9.2 (a parser and emitter of YAML documents. If you don’t know anything about YAML and why it is good: check my previous posts on the subject). A lot of new and tasty features

First, and most important: a lot of stability and consistency fixes (previous release wasn’t properly dealing with some kinds of number-like strings and with mixed-keys arrays). This release is HIGHLY recommended to anyone who uses syck-php in production. I was using this version for several weeks as a server-to-server exchange format under heavy load and coudn’t be satisfied more.

I started to dive into object-serialization and unserialization topics. Any object which implements Serializable interface can be dumped into yaml-document now. It will be stored using !php/object::ClassName signature. And, of course, you would be able load the object afterwards. Important: at the moment of loading yaml-file, all of the classes mentioned in it have to be either declared, or be available to php’s autoload mechanism.

I also implemented loading of objects with !php/array::ClassName and !php/hash::ClassName signatures. These have to implement ArrayAccess interface. Unfortunately, I didn’t implement dumping of such objects yet. That is planned for the next releae.

As always, I am open to hear any of your comments and bug-reports.

I re tested syck and it does make a BIG difference. I tested with a yaml file of about 200,000 lines which I killed after an hour while using spyc. The same file was loaded with syck in about 5 . . . → Read More: syck vs. spyc (benchmarking)]]> Regarding syck vs. spyc debate which seems to appear again and again:

p.s. I hope to find some time, to release an updated pecl-package of syck really soon. Please, remind me to do it

On the other hand, it reminds me, that I should release the new version…

Changelog:

Update is highly recommended for everyone

Something like: $timestamp = '2007-07-07 07:07:07'; $timezone = '+0300';

$obj = new DateTime($timestamp, new DateTimeZone(????));

I need this, to add proper support for YAML-timestamps in my syck extension.

In YAML, timestamps have several representations:

This is an extension for reading and writing YAML-files.

YAMLâ„¢ (rhymes with “camel”) is a straightforward machine parsable data serialization format designed for human readability and interaction with scripting languages. YAML is optimized for data serialization, configuration settings, log files, Internet messaging and filtering.

YAML . . . → Read More: Syck for PHP goes Beta (in PECL)]]> Here it is: new and shiny PECL package of Syck

This is an extension for reading and writing YAML-files.

YAMLâ„¢ (rhymes with “camel”) is a straightforward machine parsable data serialization format designed for human readability and interaction with scripting languages. YAML is optimized for data serialization, configuration settings, log files, Internet messaging and filtering.

YAML is extensively used by Symfony Framework and there is also a component for Zend Framework in development. But it’s use is not limited by something big — YAML is a perfect solution for configuration-files (way more comfortable than Ini or XML).

Some time ago, I posted installation instructions. Here is the updated version:

• Install Syck-library using your favorite package-manager (stable 0.55 version will do) [debian, freebsd, etc.]
• pecl install syck-beta
• restart Apache of Fast-CGI process (if needed)

Tell me how it works for you

Supported datatypes:

Objects are simply ignored now, though I am planning to add support for them . . . → Read More: YAML: Syck for PHP is not read-only anymore]]> One more good news for you, YAML-users.
I’ve implemented emitter functionality in php-binding of syck library. It is quite straight-forward, no fancy stuff for now, but it should work

Supported datatypes:

• associative arrays
• indexed arrays
• strings
• integers
• floats
• booleans
• null

Objects are simply ignored now, though I am planning to add support for them later. See TODO for details.

Example, to give you idea:

$data = array(
  'items' => array(
    'item 1',
    'item 2'
  ),
  'count' => 2
);
echo syck_dump($data);

take a look at my previous yaml-post for installation instructions.

Let me know how this works for you

p.s. should I change the name of that function? :-/

Some updates:

Until then, I encourage you to . . . → Read More: PHP Syck, part 2]]> Yesterday I wrote about updating PHP’s YAML-parsing extension — Syck.

Some updates:

• I believe, I fixed all memory leaks, it had (They were quite large, must tell you)
• Why (Syck’s author) told me, that there will be new release in a month or so, which will include my patches

Until then, I encourage you to build php-extension using sources from subversion

Instructions (for those who need them):

1. Install Syck-library using your favorite package-manager (stable 0.55 version will do)
2. svn export http://code.whytheluckystiff.net/svn/syck/trunk/ext/php/ syck-php
3. cd syck-php
4. phpize
5. ./configure
6. make
7. sudo make install
8. add extension=syck.so to your php.ini file
9. restart apache or fastcgi processes
