Hi,
I'm very new to PHP, and am toying with some COM samples... specifically
the Windows FileSystem object.
This object has a property Drives, which returns a collection of Drive
objects (one for each drive letter). How can I enumerate this collection?
Here's the very basics:
$fs = new COM("Scripting.FileSystemObject");
$drives = $fs->Drives;
echo("$drives->Count Drives");
This much works correctly (I get "4 Drives").
The next logical thing I'd like to do is something like:
foreach($drives as $drive)
{
echo $drive->VolumeName;
}
....however, I don't get the expected results. If I add a diagnostic
echo, it get's fired once (rather than 4 times) and the existing echo
neither returns anything or any error.
Thoughts?
Is this a syntax thing, or a fundamental "PHP isn't VB mate"
misunderstanding on my part? ;)
Ta,
Jon 4 3980

Hi Jon,
Have you tried:
var_dump($drives);die;
for debugging? This should outline the exact contents and type of
$drives.. maybe there's an issue in the storage method (I've not tried
personally, so just guessing =) ).
Regards,
Ian

Yup, PHP isn't VB. You have to call methods of IEnumVariant to enumerate
through a collection.
$fs = new COM("Scripting.FileSystemObject");
$drives = $fs->Drives;
echo $drives->Count;
$drives->Reset();
while($drive = $drives->Next()) {
echo $drive->VolumeName;
}
If you need to use COM, stick with VB. COM support in PHP isn't terribly
stable.

Chung,
Thanks -- that works fine. That certainly wasn't obvious to me at
all... the Next() and Reset() functions seem to be built-in Array functions?

COM support is not integrated into PHP as it's in VB. Next and Reset are
methods of the IEnumVariant interface, which is provided by the COM
collection object.
