Bug #78226 [NEW]: Unexpected __set behavior

From: dirk dot gerigk at tui dot com Operating system: Linux PHP version: 7.4Git-2019-06-28 (Git) Package: Class/Object related Bug Type: Bug Bug description:Unexpected __set behavior Description: ------------ Maybe it is a not implemented yet in alpha1, but i found a unexpected behavior when using __set / __get. I will only point to one issue i found. So, when you use __set in a class and typ-hint a property, the __set method is always called. Side Note (other issue): Is it normal that you have to make every type-hinted property nullable? Because when you have: public string $bar; And do: (new A)->bar; You get: Fatal error: Uncaught TypeError: Typed property A::$bar must be string, null used Is that wanted in that way? Test script: --------------- class A { public string $bar; public $foo; final public function __get($name){ print "get_$name "; } final public function __set($name,$arg){ print "set_$name "; } } $obj = new A; $obj->bar=''; $obj->foo=''; var_export($obj); Expected result: ---------------- A::__set_state(array( 'bar' => '', 'foo' => '', )) Actual result: -------------- set_bar A::__set_state(array( 'foo' => '', )) -- Edit bug report at https://bugs.php.net/bug.php?id=78226&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=78226&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=78226&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=78226&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=78226&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=78226&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=78226&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=78226&r=needscript Try newer version: https://bugs.php.net/fix.php?id=78226&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=78226&r=support Expected behavior: https://bugs.php.net/fix.php?id=78226&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=78226&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=78226&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=78226&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=78226&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=78226&r=dst IIS Stability: https://bugs.php.net/fix.php?id=78226&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=78226&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=78226&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=78226&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=78226&r=mysqlcfg
