I have built a demo script + dll and posted instructions on this Github repo: https://github.com/david-garcia-garcia/72569test What happens is that, if you pass an array to .Net, and any of the elements inside the array is a reference, then the whole array arrives to .Net as full of NULLS (keeping the original length though). This did not happen in previous versions of PHP. If you run the script in PHP 5.6 x86 NTS and PHP 7.0.8 NTS x64 you will se that it outputs different data. Thanks! ------------------------------------------------------------------------ [2016-07-11 13:22:50] ab@php.net Thanks for the report. I'm willing to fix this issue, but lack on a way to reproduce. Could you please supply a complete code for the C# class and the way to bind it in PHP, so debugging can be done? Thanks. ------------------------------------------------------------------------ [2016-07-09 20:08:31] deivid dot garcia dot garcia at gmail dot com Description: ------------ Arrays passed to .Net when calling .Net object methods using COM class (probably DOTNET too but have not tested) arrive as empty arrays. This was NOT happening in PHP < 7, it's a regression. Other simple types are passed on properly (such as strings). Test script: --------------- The bug CANNOT be demonstrated without building a specific .Net dll that takes an array as input. In .Net: public object MyNiceMethod(object[] parameters) { // In PHP7 parameters comes in as an EMPTY array // when in PHP < 7 it was an array of string, integers and whatever // you passed in from PHP. } In PHP: $a = new COM("{CLASSID}"); $a->MyNiceMethod(["string1", "string2", 56, "string3", [1, 2, 3]]); ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=72569&edit=1
