Hi,

i have just started experimenting with PHP extension in C.
Works nicely so far.

Does anybody know how to read (no write needed) global PHP vars
within the C extension code ? I am not that familiar with the zend API
yet and haven't found sample code on the net so far.

I need to go for some piece in the $_SERVER[] during a C function.

Thanx
