I can see how to add to an associative array :- zval *aa; MAKE_STD_ZVAL(aa); array_init(aa); Hi, I am working on a C extension module for PHP and am wondering about an API issue. I can see how to add to an associative array :- zval *aa; MAKE_STD_ZVAL(aa); array_init(aa); add_assoc_string(aa, "test", "test value", 1); add_assoc_string(aa, "test2", "test value2", 1); but how do I transverse an associative array of values in a for loop simular to using "foreach" in PHP ? Hope this is not too OT for this list, but I could not find a better place to ask the question. I have looked through the API SVN sources and this seems like a possible blind spot.

Ah, got it many thanks, Aaron --- ## #54959 — Aaron Gray — 2011-08-26T00:52:59+00:00 URL: https://externals.io/message/54953#54959 · In reply to: #54957 "Christopher Jones" wrote in message news:4E56E662.90804@oracle.com... > > > > > […] > > http://svn.php.net/viewvc/php/php-src/branches/PHP_5_4/ext/standard/ Chris, How much can I access as a PHP plugin dll or shared object ? Thinking about it what I really want to do is see if a key exists in an array and get its type to see if it is BOOL and that it is TRUE.

For this, you will need to call zend_hash_find (or zend_symtable_find if there's a possibility of keys like "0" that have to be treated as 0). If you get SUCCESS, the key exists and you'll be getting zval **, then either check it's type and value with Z_TYPE_PP and Z_LVAL_PP or call zend_is_true(*val) to get generic truth value (like if(), etc. do). -- Stanislav Malyshev, Software Architect SugarCRM: http://www.sugarcrm.com/ (408)454-6900 ext. 227 --- ## #54962 — Aaron Gray — 2011-08-26T03:19:17+00:00 URL: https://externals.io/message/54953#54962 · In reply to: #54960 Hi Stas, "Stas Malyshev" wrote in message news:4E56F0D6.20608@sugarcrm.com... > Hi! > > > > […] > > For this, you will need to call zend_hash_find (or zend_symtable_find if > there's a possibility of keys like "0" that have to be treated as 0). Okay, found it, "zend_hash.h", so that should be accessable to my module :) > If you get SUCCESS, the key exists and you'll be getting zval **, then > either check it's type and value with Z_TYPE_PP and Z_LVAL_PP or call > zend_is_true(*val) to get generic truth value (like if(), etc. do). Great. That seems alot simpler.
