you can do this only with a not-so nice hack. essentially you have to
manually search the active symbol table stack for a zval * which equals your
variable. zend_hash_find wont help you, since you're doing a "reverse"
lookup. so the process is something like (totally OTTOMH)
HashTable *table = EG(active_symbol_table);
char *name_im_looking_for = NULL;
while (table && !name_im_looking_for) {
if (name_im_looking_for = find_name(table, zval
*zval_ptr_im_looking_for)) break;
table = get_prev_symbol_table(); /* you're on your own here - i have
no idea how to do this*/
}
static char *find_name(HashTable * table, zval *zval_ptr_im_looking_for)
{
zval **entry;
zend_hash_internal_pointer_reset(table);
while (zend_hash_get_current_data( hash, (void**)&entry) == SUCCESS) {
if (*entry = zval_ptr_im_looking_for) {
char *string_key;
ulong num_key, key_len;
if (HASH_KEY_IS_STRING ==
zend_hash_get_current_key_ex(hash, &string_key, &key_len, &num_key, 0,
NULL)) {
return string_key:
}
}
zend_hash_move_forward(hash);
} /* while */
return NULL;
}
