ID: 52110 Comment by: jbwdevries at gmail dot com Reported by: jbwdevries at gmail dot com Summary: get_defined_vars is inconsistent with $this Status: Bogus Type: Bug Package: Unknown/Other Function Operating System: Windows XP [Version 5.1.2600] PHP Version: 5.3.2 New Comment: I understand your reasoning; however, shouldn't you assume from the use of get_defined_vars() that $this is needed? Previous Comments: ------------------------------------------------------------------------ [2010-06-17 17:05:02] johan...@php.net Thank you for taking the time to write to us, but this is not a bug. Please double-check the documentation available at http://www.php.net/manual/ and the instructions on how to report a bug at http://bugs.php.net/how-to-report.php For performance reasons $this and super-globals are only populated when they are needed. If the aren't needed they don't exist. ------------------------------------------------------------------------ [2010-06-17 16:40:09] jbwdevries at gmail dot com Description: ------------ get_defined_vars() only contains the $this variable entry when $this is assigned or returned. In all other cases (no use, gettting or setting of property, callign a method) the $this entry is missing from the list. Test script: --------------- // Full example is at http://pastebin.com/FDJzCTRG class Test { //... public function testNoThis() { echo __METHOD__ . PHP_EOL; var_dump(array_keys(get_defined_vars())); } //... } $t = new Test(); $t->testNoThis(); Expected result: ---------------- Test::testNoThis array(1) { [0]=> string(4) "this" } Test::testThisGet array(1) { [0]=> string(4) "this" } Test::testThisSet array(1) { [0]=> string(4) "this" } Test::testThisCall array(1) { [0]=> string(4) "this" } Test::testThisUse array(1) { [0]=> string(4) "this" } Actual result: -------------- Test::testNoThis array(0) { } Test::testThisGet array(0) { } Test::testThisSet array(0) { } Test::testThisCall array(0) { } Test::testThisUse array(1) { [0]=> string(4) "this" } ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/bug.php?id=52110&edit=1
