From: reeze dot xia at gmail dot com Operating system: PHP version: master-Git-2012-09-02 (Git) Package: Scripting Engine problem Bug Type: Feature/Change Request Bug description:Disallow some magic methods been generators Description: ------------ magic method are called in a special way, if those methods was defined as generator, most of them will not work as expected. We could disallow them when compiling. Test script: --------------- class A { public function __construct(array $data) { $this->initData = $data; // maybe more initialization... var_dump($this->initData); foreach$(this->initData as $v) { yield $v; } } } $a = new A(array(1, 2)); // constructor didn't get called. so does the that magic methods: http://www.php.net/manual/en/language.oop5.magic.php most of them are meanning less if they are generators. *some of them* maybe useful if they return value but not void. Those could be allowed: __call(), __callStatic(), __get(), __invoke() but those seems meaningless to be generators __construct(), __destruct(), __set(), __isset(), __unset(), __sleep(), __wakeup(), __toString(), __set_state() and __clone(), -- Edit bug report at https://bugs.php.net/bug.php?id=62994&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=62994&r=trysnapshot54 Try a snapshot (PHP 5.3): https://bugs.php.net/fix.php?id=62994&r=trysnapshot53 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=62994&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=62994&r=fixed Fixed in SVN and need be documented: https://bugs.php.net/fix.php?id=62994&r=needdocs Fixed in release: https://bugs.php.net/fix.php?id=62994&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=62994&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=62994&r=needscript Try newer version: https://bugs.php.net/fix.php?id=62994&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=62994&r=support Expected behavior: https://bugs.php.net/fix.php?id=62994&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=62994&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=62994&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=62994&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=62994&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=62994&r=dst IIS Stability: https://bugs.php.net/fix.php?id=62994&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=62994&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=62994&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=62994&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=62994&r=mysqlcfg
