Hello All,
I am trying to zip data in a PHP program using the following code. The
resulting file (ndfdViaPipe.kmz) is zip'ed but the data in the archive
lacks a file name. So when a program like Google Earth tries to process
the file, it fails. When I bring ndfdViaPipe.kmz into WinZip, the file
has no name but can otherwise be extracted just fine. Once extracted,
Google Earth can process the file. Does anyone know how I might add the
"file name" information to the ndfdViaPipe.kmz? The reason I'm trying
to use pipes is to avoid creating a file with the dynamically created
data in $kml_string. The plan is to send $kmz_content out in a SOAP
service message with the payload as base64 encoded file. If there is a
better way to accomplish this I am certainly open to suggestions.
In advance, thanks for any help you care to offer.
John
