Edit report at https://bugs.php.net/bug.php?id=76354&edit=1 ID: 76354 Updated by: cmb@php.net Reported by: biser dot antonov at gmail dot com Summary: ArrayObject doesn't call the constructor of a custom iterator when foreach Status: Open -Type: Bug +Type: Documentation Problem Package: SPL related Operating System: Debian PHP Version: 7.2.5 Block user comment: N Private report: N New Comment: Well, only constructors without any mandatory parameters could be successfully called anyway, since there is no way to specify the arguments. Anyhow, given the long standing behavior, and that it is apparently a design decision, I'm switching to documentation problem.

Tested in the official php docker container: https://github.com/docker-library/php/blob/b045ba7c51ceed8a495beb8ea7274df48a3c70e1/7.2/stretch/cli/Dockerfile Test script: --------------- class I extends ArrayIterator { public function __construct(array $array = array(), $flags = 0) { exit(__FILE__ . ':' . __LINE__); } } $a = new ArrayObject([1, 2, 3], 0, I::class); foreach ($a as $key => $value) { // do something } Expected result: ---------------- I expected the script to call I::__construct() and exit Actual result: -------------- The script finished without interruption ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=76354&edit=1
