Description: ------------ Squiz.Classes.SelfMemberReference report a violation if you use the classname to reference to static function in closure. Test script: ---------------,unified,1647,5,t3lib/utility/class.t3lib_utility_array.php at line 82 Expected result: ---------------- The sniff should not report a violation. Actual result: -------------- Must use "self::" for local static member reference

Your test script URL requires a username and password and I can't find that file in the typo3 repo. Can you please post a short sample of code to replicate the issue so I know I'm fixing the right problem.

This bug has been fixed in SVN. If this was a documentation problem, the fix will appear on by the end of next Sunday (CET). If this was a problem with the website, the change should be live shortly. Otherwise, the fix will appear in the package's next release. Thank you for the report and for helping us make PEAR better.
