In that case take a look at where such is implemented in php-src, dns_get_record() is an example despite the slightly clouded code: http://git.php.net/?p=php-src.git;a=blob;f=ext/standard/dns.c;h= f92015eee90d3e93a801e93d6381d89923825166;hb=refs/heads/master#l1011 See $weight_list: - Check if the argument is passed - zval_dtor() - Populate it (ZVAL_LONG is the same) The main difference from your code is to use 'z' (lower case) in ZPP, and then use zval* (which is what 'z' returns). You also need set 1 for the first param of ZEND_ARG_INFO (specify that it is a ref param) otherwise it won't use the changed val... Jakub
