[PHP-DEV] how to debug a php script ( the C code beneath it)

[Adi Mutu]

Hello,

Perhaps this is a stupid question, but i haven't coded in C in years and i'm 
not very familiar with development/debugging tools. If I have a php script say 
20 lines,
How can I see a path of the corresponding C code which is executed? What If i 
would like to break at a certain php line in the script, is it possible?

Thanks,
