Input paramters...

I've got a question about input parameters: After calling zend_get_parameters, are the zval's that it returns appear to be deallocated automatically when the function terminates. Is this proper behavior? The issue is as follows: Say I have a PHP function that accepts a string, calls zend_get_parameters and passes the value.str.val member to a C function that accepts a char*. If that C function passes the char* to a C++ function that sets a private member variable (also of type char*) equal to it, future references to that private member variable return the wrong value. In fact, they frequently return PHP function names. I assume that what's happening is that the zval is getting deallocated and another variable is getting allocated and used at the same address. I guess I could get around the whole mess by estrdup'ing string parameters that this behavior apply's to, but should I really have to do that? Thanks, Dave Muse
