Edit report at https://bugs.php.net/bug.php?id=77119&edit=1 ID: 77119 Comment by: josh at engramdesign dot com dot au Reported by: josh at engramdesign dot com dot au Summary: array_column has changed behaviour for classes Status: Not a bug Type: Bug Package: Arrays related Operating System: Centos PHP Version: 7.0.32 Block user comment: N Private report: N New Comment: Well, I'm an idiot. The expected and actual results are around the wrong way. So sorry about that. I can't see anywhere to edit my original post either (sorry, not used to this bug tracker). So what its returning is an empty array when it shouldn't be. Does that make more sense now? Previous Comments: ------------------------------------------------------------------------ [2018-11-08 03:09:38] requinix@php.net Your expected behavior is incorrect. What the function is doing, and as you pointed out has been doing since 7.0.0, it was it should be doing: returning an array with the "name" properties extracted from the array of objects that was passed as the first argument. ------------------------------------------------------------------------ [2018-11-08 02:32:29] josh at engramdesign dot com dot au Then why does the output for "Output for hhvm-3.17.3 - 3.22.0, 7.0.0 - 7.3.0rc4" show the following? object(stdClass)#1 (1) { ["name"]=> string(4) "Test" } array(1) { [0]=> string(4) "Test" } I will note that 3v4l doesn't have 7.0.32 available to test, and it works as expected in 7.0.31. ------------------------------------------------------------------------ [2018-11-08 02:14:29] peehaa@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 In specific check the documentation of the function you are using including the possible changelog http://php.net/manual/en/function.array-column.php#refsect1-function.array-column-changelog ------------------------------------------------------------------------ [2018-11-08 02:02:20] peehaa@php.net > This worked fine in previous 7.0.x versions. 3v4l disagrees: https://3v4l.org/Nsjvl ------------------------------------------------------------------------ [2018-11-08 01:47:46] josh at engramdesign dot com dot au Description: ------------ A recent update to 7.0.32 has caused this bug. Please refer to the reproducible example where an array of classes is supplied to array_column. This worked fine in previous 7.0.x versions. Test script: --------------- $class = new \stdClass(); $class->name = 'Test'; var_dump($class); $names = array_column([$class], 'name'); var_dump($names); Expected result: ---------------- object(stdClass)#769 (1) { ["name"]=> string(4) "Test" } array(0) { } Actual result: -------------- object(stdClass)#769 (1) { ["name"]=> string(4) "Test" } array(1) { [0]=> string(4) "Test" } ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=77119&edit=1
