Summary0002124: Xdebug incorrectly reports that there are no children for static closure properties, even thought there are
Description

If you have a static closure property, the children attribute in the response to the context_get message will be "0" but then the numchildren attribute will be "1" and there will be a child node with the closure data

Steps To Reproduce

This can be easily reproduced by running the xdebug/tests/debugger/bug02094.phpt test. The output of this test for the context_get command is:

<response xmlns="urn:debugger_protocol_v1" xmlns:xdebug="https://xdebug.org/dbgp/xdebug" command="context_get" transaction_id="4" context="0"><property name="::" fullname="::" type="object" classname="Test" children="1" numchildren="1"><property name="::bar" fullname="::bar" type="object" facet="closure static public" classname="Closure" children="0" numchildren="1" page="0" pagesize="32"><property facet="virtual readonly" name="{closure}" type="array" children="1" page="0" pagesize="2" numchildren="1"><property facet="readonly" name="function" type="string"><![CDATA[{closure}]]></property></property></property></property></response>

And it should be

 <response xmlns="urn:debugger_protocol_v1" xmlns:xdebug="https://xdebug.org/dbgp/xdebug" command="context_get" transaction_id="4" context="0"><property name="::" fullname="::" type="object" classname="Test" children="1" numchildren="1"><property name="::bar" fullname="::bar" type="object" facet="closure static public" classname="Closure" children="1" numchildren="1" page="0" pagesize="32"><property facet="virtual readonly" name="{closure}" type="array" children="1" page="0" pagesize="2" numchildren="1"><property facet="readonly" name="function" type="string"><![CDATA[{closure}]]></property></property></property></property></response>

(the difference is in the children attribute for the ::bar property)

Additional Information

Tested in Ubuntu running under Docker in a MacOS system with PHP 8.0.19 but I suspect it happens in all PHP versions as the test is passing everywhere

Sorry for the mangled XML, when I pasted it when creating the issue, it was OK, hope you can work with this

No worries about the XML - it's something the issue tracker does. When I 'edit' it shows normal.

Also, I've managed to track this down, and waiting for CI to approve the merge: https://github.com/xdebug/xdebug/pull/859 — this will go into Xdebug 3.2 and later.
