Bug #80705 [NEW]: If you unset a class property, the __get remembers the original type.

From: vali dot dr at gmail dot com Operating system: Linux PHP version: 8.0.1 Package: Scripting Engine problem Bug Type: Bug Bug description:If you unset a class property, the __get remembers the original type. Description: ------------ If you unset a property on a class, the __get magic method gets called (good), but it's return must match the original, now unset, property type. (bug?) There should be a way to fully remove that property, either by reflection or unset (including the return time) Test script: --------------- <?php declare(strict_types=1); class Sample { public int $foo = 123; # Start as in INT public function __construct() { unset($this->foo); # Remove the property } public function __get(string $name) { # Gets called, since foo dies not exist. echo "__GET\n"; # Validate that it's called return "string"; # Cannot return string since foo was an int... } } $test = new Sample(); echo $test->foo; # Throws error, since __get returns a string instead of an int Expected result: ---------------- __GET string Actual result: -------------- __GET PHP Fatal error: Uncaught TypeError: Cannot assign string to property Sample::$foo of type int in ... .php:18 Stack trace: #0 {main} thrown in ... -- Edit bug report at https://bugs.php.net/bug.php?id=80705&edit=1 -- Fix committed: https://bugs.php.net/fix.php?id=80705&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=80705&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=80705&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=80705&r=needscript Try newer version: https://bugs.php.net/fix.php?id=80705&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=80705&r=support Expected behavior: https://bugs.php.net/fix.php?id=80705&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=80705&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=80705&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=80705&r=globals PHP version support discontinued: https://bugs.php.net/fix.php?id=80705&r=phptooold Daylight Savings: https://bugs.php.net/fix.php?id=80705&r=dst IIS Stability: https://bugs.php.net/fix.php?id=80705&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=80705&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=80705&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=80705&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=80705&r=mysqlcfg
