Here’s a summary of the state of YAML in PHP:
- Wrappers to C libraries: You’ll probably want these if you need sheer speed:
- php-yaml: Wrapper for LibYAML. Available as a PECL extension; it is also the one on PHP’s docs.
- syck: Binding to syck; also available as a PECL extension. (dated, see below)
-
Pure PHP implementations:
At the time of this writing, the latest versions release dates for the aforementioned libraries and the versions of the YAML spec (1.2 is the latest version) they support are:
php-yaml 1.3.0 2016-09-24 YAML 1.1 [PHP 5]
php-yaml 2.0.0 2016-09-24 YAML 1.1 [PHP 7]
syck 0.9.3 2008-11-18 YAML 1.0
sfYaml 3.3.5 2017-06-15 YAML 1.1, most of 1.2
