## Runtime Configuration

The behaviour of these functions is affected by settings in php.ini.

Yaml Configure Options
Name | Default | Changeable | Changelog
--- | --- | --- | ---
yaml.decode_binary | 0 | PHP_INI_ALL |
yaml.decode_php | 1 | PHP_INI_ALL |
yaml.decode_timestamp | 0 | PHP_INI_ALL |
yaml.output_canonical | 0 | PHP_INI_ALL |
yaml.output_indent | 2 | PHP_INI_ALL |
yaml.output_width | 80 | PHP_INI_ALL |

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_php` boolean

  On by default, but can be set to off to prevent serialized php objects which have the explicit tag "!php/object" from being unserialized.

`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.
