Bug #76206 [NEW]: Arrays in objects using splat aren't passed by reference in a dynamic call

From: d28b312d at opayq dot com Operating system: * PHP version: Irrelevant Package: Unknown/Other Function Bug Type: Bug Bug description:Arrays in objects using splat aren't passed by reference in a dynamic call Description: ------------ If you have an object with an array parameter, and you try to pass that to a closure which accepts parameters by reference, the parameters aren't taken in by reference and instead by value. Modifying the below script to use $foo instead of $this->foo in both cases will work, but using the instance assigned to an object parameter seems to pass the values by value without an error, instead of by reference like the function implies. Note: If you try to use call_user_func_array it throws a message saying it's passing by value to a reference expecting function which is at least better than showing nothing and just treating as if it's a value (but both are wrong!). `PHP Warning: Parameter 1 to {closure}() expected to be a reference, value given` Test script: --------------- <?php class Foo { private $foo; public function call(Closure $cl, $foo) { $this->foo = $foo; $cl(...$this->foo); var_dump($this->foo); return $cl(...$this->foo); } } $f = new Foo; echo $f->call(function(&$i){return ++$i;}, [0]); Expected result: ---------------- /tmp/classtest.php:11: array(1) { [0] => int(1) } 2 Actual result: -------------- /tmp/classtest.php:11: array(1) { [0] => int(0) } 1 -- Edit bug report at https://bugs.php.net/bug.php?id=76206&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=76206&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=76206&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=76206&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=76206&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=76206&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=76206&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=76206&r=needscript Try newer version: https://bugs.php.net/fix.php?id=76206&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=76206&r=support Expected behavior: https://bugs.php.net/fix.php?id=76206&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=76206&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=76206&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=76206&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=76206&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=76206&r=dst IIS Stability: https://bugs.php.net/fix.php?id=76206&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=76206&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=76206&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=76206&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=76206&r=mysqlcfg
