PHP array to char **

Hi,

I'm working on some improvements to the pgsql extension and I would like
to know how to convert a zval* that points to a PHP array to a char**
that I can pass to the pgsql API functions. The API function takes
const char** so it will not modify the string, but the string must exist
for the duration of the API call...

I've been looking at other code that does similar things, but I can't
help wondering if there is a simple, straightforward way of doing it?

Cheers,

Chris

Just look at ext/standard/array.c

There are dozens of examples of how to walk a HashTable in there.
