array-arguments in extensions

geon

Does anyone have some easy-to-understand information on how to use array-arguments in my php-extension (written in C)?

I sucessfully compiled yhe dll, and managed to return an array, but cant andrestand how to recieve one. The source-code in the mysql and array extensions were of no use...

There's nice and simple API in Zend/zend_hash.[c|h] inside of PHP source code distribution.
And don't forget to read Zend APIdoc and/or PHP manual.

I've read all the php-extension documentation, and I (think I) succeded with reciveing the array as a zval.

But I have still no idéa of how to use this zval to read from the hash-table. The zend API is close to totaly undocumented!

The only thing I want to do, is to read 64 integers, indexed from 0 to 63.

Can anyone help me out? I should be easy...

Learn to read C source code!
You should be able to read it just like any book.

you will need the following functions:
- zend_hash_internal_pointer_reset_ex()
- zend_hash_move_forward_ex()
- zend_hash_get_current_key_ex()
- zend_hash_get_current_data_ex()

There are same functions without "_ex" in Zend API, but it's safer not to use them.

Now look at these functions' definitions in zend_hash.h / zend_hash.c, search for them in sources of other extensions and explore the code.

I'd paste a code from my extension (I had to use arrays very intensively), but it's too large and will be less readable in this forum than in a .c file.

good luck =)
