@Ann and @Linda, are you sure that this rule is really used and usable in PHP because for sure in Java or C#, there are lot of methods returning a boolean value and which can start by something else than "is", for instance :
\[~ann.campbell.2] & [~freddy.mallet] this rule comes from PHPMD see http://phpmd.org/rules/naming.html#booleangetmethodname[documentation].
Indeed PHPMDP rule suggest 2 options:
* "isX"
* "hasX"
Also the rule is limited to getter that has the ``++@return++`` documentation tag with boolean. IMO it would be worth to explicitly mention it in the description additionally to the code snippet, WDYT Ann ?
