Bug #70437 [NEW]: Changes to static properties in trait methods are not reflected in the class

From: davey Operating system: OSX/Linux PHP version: 7.0.0RC2 Package: Scripting Engine problem Bug Type: Bug Bug description:Changes to static properties in trait methods are not reflected in the class Description: ------------ If you have a trait that defines a static property, and you modify said property from within a trait inherited method, the modifications are done to a trait instance of the property, as opposed to the inherited-from-trait static property within the class. The behavior differs slightly in PHP 5.4.7 - 5.5.29 in that if the methods are instance methods, then they will correctly modify the inherited-from-trait static property, but are broken for static methods. 5.6.0+ has the same behavior for static and instance methods. Test script: --------------- Static methods: https://3v4l.org/UZ6gq Instance methods: https://3v4l.org/piUFm Expected result: ---------------- Should modify the inherited-from-trait static property within the class Actual result: -------------- Modifies a trait-specific copy of the static property -- Edit bug report at https://bugs.php.net/bug.php?id=70437&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=70437&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=70437&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=70437&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=70437&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=70437&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=70437&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=70437&r=needscript Try newer version: https://bugs.php.net/fix.php?id=70437&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=70437&r=support Expected behavior: https://bugs.php.net/fix.php?id=70437&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=70437&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=70437&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=70437&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=70437&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=70437&r=dst IIS Stability: https://bugs.php.net/fix.php?id=70437&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=70437&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=70437&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=70437&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=70437&r=mysqlcfg
