[PHP-DEV] PHP COM Array of VARIANT as out parameter

[Alejandro Gonzalez]

Dear All,

 

I'm trying to use a COM dll function like that:

 

HRESULT Reader::QueryData(out, ref] float * p1, [out, ref] float * p2, [out,
ref] VARIANT * pData)

 

PHP code:

 

$p1 = 0.0;

$p2 = 0.0;

//$p3 = [];

//$p3 = array();

//$p3 = new VARIANT();

//$p3 = new VARIANT([], VT_VARIANT|VT_ARRAY);

//$p3 = new VARIANT(new ArrayObject(), VT_VARIANT|VT_ARRAY);

$result = $reader->QueryData($p1, $p2, $p3);

 

Error: Parameter 2: The types do not match.

 

com_print_typeinfo()
/* DISPID=9 */
function QueryData(
/* VT_PTR [26] [out] --> VT_R4 [4]  */ &$p1,
/* VT_PTR [26] [out] --> VT_R4 [4]  */ &$p2,
/* VT_PTR [26] [out] --> VT_VARIANT [12]  */ &$p3 
)

 

I tried to declare in different ways a variable to get a returned by COM dll
function, but without success.

I can't find documentation if this kind of functionality is supported by
php_com_dotnet extension.

 

I will appreciate your support, thanks in advance.

Kind regards

Alejandro Gonzalez
