Here's a short explanation of
the configuration directives.
yaml.decode_binarybool
Off by default, but can be set to on to cause base64 binary encoded entities which have the explicit tag "tag:yaml.org,2002:binary" to be decoded.
yaml.decode_phpbool
Off by default, but can be set to on to cause serialized php objects which have the explicit tag "!php/object" to be unserialized.
yaml.decode_timestampint
Controls the decoding of both implicit and explicit "tag:yaml.org,2002:timestamp" scalars in the YAML document stream. The default setting of 0 will not apply any decoding. A setting of 1 will use strtotime to parse the timestamp value as a Unix timestamp. A setting of 2 will use date_create to parse the timestamp value as DateTime object.
yaml.output_canonicalbool
Off by default, but can be set to on to cause canonical form output.
yaml.output_indentint
Number of spaces to indent sections. Value should be between
1 and 10.
