Answer 1

I wanted to allow PHP to access shared memory that was created and written to by a Windows application. I achieved this by creating my own php extension (called php_gsect.dll). This may not be what you want but my php_gsect attaches to the global section and reads (or writes) a number of bytes which I can then manipulate.

FYI: My windows application is retreiving dynamic trend data from another system and putting the data into a named global section. The php web page is accessing the data from the global section and creating a chart (using the ESJ chart library).
