transversing associative arrays from C

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);

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.

Many thanks in advance,

Aaron

Hello,

I can see how to add to an associative array :-

Most everything you need to know about manipulating arrays can be
found in ext/standard/array.c

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.

Many thanks,

Aaron

Hi!

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).

Okay, found it, "zend_hash.h", so that should be accessable to my module :)

Great.

That seems alot simpler.

Many thanks,
