[PHP-DEV] What's wrong with these hashtable iteration code?

2014-07-20 Thread Aaron Lewis 
Hi,

I'm trying to iterate through a hash table,

But the zend_hash_get_current_key() doesn't seem to move forward:
I'm getting duplicate output at the 'fprintf' part.

   for(zend_hash_internal_pointer_reset_ex(ht, pos);
zend_hash_has_more_elements_ex(ht, pos) == SUCCESS;
zend_hash_move_forward_ex(ht, pos))
{
if (zend_hash_get_current_key (ht, string_key, num_key, 0)
!= HASH_KEY_IS_STRING)
continue;

fprintf (stderr, string key: %s\n, string_key);
}

Any ideas?

The _ex() hash iteration functions allow for iterating a hash without
modifying its internal pointer, but zend_hash_get_current_key() uses only
the internal pointer.

The function you need to use is: zend_hash_get_current_key_ex() and pass
pos to it.




 Any ideas?
