Working with arrays.

Hi Richard

Hi.

What macros exist regarding processing arrays in PHP (core not userland)?

Zend hash, see Zend/zend_hash.c for its API.

I want to pass ...

array('value1', 'value2', 'value3')

You would do something like:

PHP_FUNCTION(test)
{
zval *array;

   if (zend_parse_parameters(ZEND_NUM_ARGS() TSRMLS_CC, "a",

&array) == FAILURE) {
return;
}

   /* Z_ARRVAL_P(array) is a HashTable* ptr */

}

to a function and in the function have it converted to

'value1\0value2\0value3\0\0'.

Conventionally, I'd need to iterate the array to get the lengths of
all the elements, add the number of elements to this value and then 1
more for the trailing \0.

The move_forward, get_current etc. hash functions can be used to
iterate, see zend_hash.h:
http://lxr.php.net/opengrok/xref/PHP_TRUNK/Zend/zend_hash.h#194

I did it like so:
bitbucket.org/winapiforphp/system/src/93583820bbc1/winsystem_registry.c#cl-298

It's a little messy.

Unless there are some macros to allow to do this sort of thing more easily.
