Edit report at https://bugs.php.net/bug.php?id=77119&edit=1 ID: 77119 Updated by: requinix@php.net 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: 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. Previous Comments: ------------------------------------------------------------------------ [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.
