The behaviour of these functions is affected by settings in php.ini.
Here's a short explanation of the configuration directives.
- yaml.decode_binary boolean
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_timestamp integer
Controls the decoding of both implicit and explict "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_canonical boolean
Off by default, but can be set to on to cause canonical form output.
- yaml.output_indent integer
Number of spaces to indent sections. Value should be between 1 and 10.
- yaml.output_width integer
Set the preferred line width. -1 means unlimited.
