Doing a regular compact call to a name that doesn't exist but also never attempted to define in the same scope doesn't cause the issue. ie, a regular call to compact('foo') works fine if $foo is not defined or defined conditionally in the same scope. You can check the compact working when the variable is not on the scope: http://3v4l.org/k6bt1 And here is an example when it is defined on the scope, but conditionally will never be called: http://3v4l.org/9Z3aP Test script: --------------- if (false) { $willNeverBeDefined = true; } $result = compact('willNeverBeDefined'); var_dump($result, empty($result), $result === array()); Expected result: ---------------- array(0) { } bool(true) bool(true) Actual result: -------------- array(1) { } bool(false) bool(false) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=69198&edit=1
