From: nicolas dot grekas+php at gmail dot com Operating system: PHP version: 7.0.2 Package: Scripting Engine problem Bug Type: Bug Bug description:Wrong is_ref on properties as exposed via get_object_vars() Description: ------------ When a property is used as a reference by e.g. using array_pop on it, its is_ref flag is persisted, which turns the property into a reference, and breaks get_object_vars for example. See example script See also https://3v4l.org/dcPn6 Test script: --------------- <?php class foo { protected $bar = array('baz'); function bar() { array_pop($this->bar); $vars = get_object_vars($this); print_r($vars); $this->bar[] = array('buz'); print_r($vars); } } $f = new foo(); $f->bar(); Expected result: ---------------- Array ( [bar] => Array ( ) ) Array ( [bar] => Array ( ) ) Actual result: -------------- Array ( [bar] => Array ( ) ) Array ( [bar] => Array ( [0] => Array ( [0] => buz ) ) ) -- Edit bug report at https://bugs.php.net/bug.php?id=71336&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=71336&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=71336&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=71336&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=71336&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=71336&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=71336&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=71336&r=needscript Try newer version: https://bugs.php.net/fix.php?id=71336&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=71336&r=support Expected behavior: https://bugs.php.net/fix.php?id=71336&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=71336&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=71336&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=71336&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=71336&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=71336&r=dst IIS Stability: https://bugs.php.net/fix.php?id=71336&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=71336&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=71336&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=71336&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=71336&r=mysqlcfg
