phpdoc - Is there a PHPCS standard targeting PHP docblocks?

Question

Is there a PHPCS coding standard that would check that proper annotations (@param, @return, @throws, etc.) are present in a docblock, including the proper spacing between them?

Answer 1

Try running the following command and see if it produces what you want:

phpcs /path/to/code --standard=Squiz --sniffs=Squiz.Commenting.FunctionComment,Squiz.Commenting.FunctionCommentThrowTag,Squiz.Commenting.ClassComment,Squiz.Commenting.FileComment,Squiz.Commenting.VariableComment

If it does, you could create your own standard that just includes those sniffs, and anything else you want to check. You do this by creating a ruleset.xml file and using that as your standard.

For example, you could create a file called mystandard.xml and include the following content:

<?xml version="1.0"?>
<ruleset name="MyStandard">
  <description>My custom coding standard.</description>
  <rule ref="Squiz.Commenting.FunctionComment" />
  <rule ref="Squiz.Commenting.FunctionCommentThrowTag" />
  <rule ref="Squiz.Commenting.ClassComment" />
  <rule ref="Squiz.Commenting.FileComment" />
  <rule ref="Squiz.Commenting.VariableComment" />
</ruleset>

Then you can run this command instead:

phpcs /path/to/code --standard=/path/to/mystandard.xml

There are other things you can do in a ruleset.xml file. See the docs here: https://github.com/squizlabs/PHP_CodeSniffer/wiki/Annotated-Ruleset
