The COM problem of converting ASP to PHP

[tomyzhen]

Hi,

When I converting lines of ASP code:

ASP

<% dim keysobjs 
dim privkey 
dim pubkey 
dim seed 

Set keysobj= CreateObject("wmrmobjs.WMRMKeys") 
keysobj.GenerateSigningKeys privkey, pubkey 
seed = keysobj.GenerateSeed() 
Response.Write privkey 
Response.Write "<br>" 
Response.Write pubkey 
Response.Write "<br>" 
Response.Write seed 
%> 
 

To the PHP one:

<? 
$com = new COM("wmrmobjs.WMRMKeys"); 
$com->GenerateSigningKeys($privkey,$pubkey); 
$seed = $com->GenerateSeed(); 

echo "Private key=".$privkey; 
echo "<br>"; 
echo "Public key=".$pubkey; 
echo "<br>"; 
echo "Seed=".$seed; 
?> 

I can obtain the value of $seed, but the $privkey and $pubkey are null,
kindly check the code for me, thx...
