[xdebug-general] DBGp: determine the collection type (array vs hash) OR get full names from the eval() call

Hello!

Is there any way to determine PHP collection type (array with integer keys
vs dictionary with object keys) via DBGp protocol?

property_get()result contains full names, i.e.

Sent:

property_get -i 67 -n $wp_styles -p 0

Received:

<response xmlns="urn:debugger_protocol_v1"
xmlns:xdebug="http://xdebug.org/dbgp/xdebug" command="property_get"
transaction_id="67">

   <property name="$wp_styles" fullname="$wp_styles" address="80382416"
type="object" children="1" classname="WP_Styles" numchildren="16">

      <property name="registered" fullname="$wp_styles-&gt;registered"
facet="public" address="22825144" type="array" children="1"
numchildren="18">

         <property name="wp-admin"
fullname="$wp_styles-&gt;registered['wp-admin']" address="22824896"
type="object" children="1" classname="_WP_Dependency" numchildren="6">

        .

But when eval() is called, there are no full names there:

Sent:

eval -i 110 -c 0 -- JHdwX3N0eWxlcw== ($wp_styles)

Received:

<?xml version="1.0" encoding="UTF-8"?>

<response xmlns="urn:debugger_protocol_v1"
xmlns:xdebug="http://xdebug.org/dbgp/xdebug" command="eval"
transaction_id="110">

  <property address="12634596" type="object" children="1"
classname="WP_Styles" numchildren="16">

     <property name="registered" facet="public" address="22826024"
type="array" children="1" numchildren="18">

        <property name="wp-admin" address="22825824" type="object"
children="1" classname="_WP_Dependency" numchildren="6">

.

If I want to read the contents of child variables (below max_depth), I need
to invoke property_get() for each of them, using full names. Eval gives no
full names, so when constructing full name from the chain of parent names, I
need a way to distinguish integer keys from object ones, i.e.
($wp_styles->registered['wp-admin'] vs $wp_styles->registered[wp-admin]). In
the current case 'wp-admin' does not look like an integer, but one can use
string keys which may be looking unclear (my_array[123] vs my_array['123'])?
If I knew which type of collection I have I could construct a valid full
name. Or, alternatively, I need a way to get a valid full name from eval()
call.

Using XDebug 2.1.0-dev on Windows Vista.

Thanks for help,
