Bug #81114 [NEW]: Can't bind_results directly to class properties in strictly_typed constructor

From: clockwork dot singularity at gmail dot com Operating system: Ubuntu PHP version: 7.4.20 Package: MySQLi related Bug Type: Bug Bug description:Can't bind_results directly to class properties in strictly_typed constructor Description: ------------ I have a class which initializes itself from a database. This works entirely fine normally, but when I declare(strict_types=1), I get this lovely type error instead: `Uncaught Error: Cannot access uninitialized non-nullable property MyClass::$name by reference in MyClass.php:110` While this is technically correct, it feels like the type system is being too aggressive in this situation. My current workarounds are to either: - Not declare strict_types in my models - or bind to local variables, then assign the properties from there (This isn't ideal, as I have ~20 properties, and introduces an additional point of human error) Test script: --------------- declare(strict_types=1); class ExampleModel { public int $id; public string $name; public function __construct($id) { $db = new mysqli(); $stmt = $db->prepare("SELECT name FROM table WHERE id = ?"); $stmt->bind_param('d', $id); $stmt->bind_result($this->name); } } -- Edit bug report at https://bugs.php.net/bug.php?id=81114&edit=1 -- Fix committed: https://bugs.php.net/fix.php?id=81114&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=81114&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=81114&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=81114&r=needscript Try newer version: https://bugs.php.net/fix.php?id=81114&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=81114&r=support Expected behavior: https://bugs.php.net/fix.php?id=81114&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=81114&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=81114&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=81114&r=globals PHP version support discontinued: https://bugs.php.net/fix.php?id=81114&r=phptooold Daylight Savings: https://bugs.php.net/fix.php?id=81114&r=dst IIS Stability: https://bugs.php.net/fix.php?id=81114&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=81114&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=81114&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=81114&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=81114&r=mysqlcfg
