bug #13262 [Yaml] Improve YAML boolean escaping (petert82, larowlan)
This PR was merged into the 2.3 branch. Discussion ---------- [Yaml] Improve YAML boolean escaping | Q | A | ------------- | --- | Bug fix? | yes | New feature? | no | BC breaks? | no | Deprecations? | no | Tests pass? | yes | Fixed tickets | #13209 | License | MIT | Doc PR | None This PR ensures that PHP [values which would be interpreted as booleans][1] in older versions of the YAML spec are escaped with single quotes when dumped by the Dumper. For example, dumping this: ```php array( 'country_code' => 'no', 'speaks_norwegian' => 'y', 'heating' => 'on', ) ``` Will produce this YAML: ```yaml country_code: 'no' speaks_norwegian: 'y' heating: 'on' ``` [1]: http://yaml.org/type/bool.html Commits -------8fa056b
