I had sent a follow up off list, but just to quickly explain the PHP 
binding...
For security reasons I implement  custom 
xmlParserInputBufferCreateFilename and xmlOutputBufferCreateFilename 
handlers, which are set on request initialization and reset on request 
termination, as not to cause problems with other languages, Apache mods, 
or other web server plugins.
I assume a PHP extension is being written here. All the xml I/O is 
handled via PHP streams, so there is absolutely no need to touch, nor 
will it work, trying to manipulate the libxml I/O handlers. If it is not 
a PHP extension and the request/call not being made within the context 
of PHP then there would be no change to the handlers and PHP would not 
play a part in this.
