Description: ------------ According to standards ( http://framework.zend.com/manual/en/coding-standard.naming-conventions.html ) a protected or private property must have a leading underscore. It is not detected, but an (incorrect) error is generated for invalid "camelCaps". Test script: --------------- <?php class someClass { protected $_var = true; } Actual result: -------------- 5 | ERROR | Variable "_var" is not in valid camel caps format

For a `trait` that is. For `class` it is working. Sorry!

The Zend standard inside PHP_CodeSniffer *is not* the current Zend Framework coding standard. It is heavily out of date (by many many years) and nobody has ever contributed a new one. But people still use it, so I have to leave it in there for now. I'm not sure if a Zend Framework coding standard exists, but it would be worth having a look around their documentation first.

Sorry, confused both standards. If it is not maintained that is okay to. Just got confused with a sniff that works well with classes failing on a trait. Updated example: trait someTrait { protected $_var = false; }
