hi,
Have you tried looking at how the parse_ini_file function works? that
should answer your questions on this.

Hi,
I'm new at PHP internals and have read the 'Extension Writing' tutorial
(part 1-3) of devzone.zend.com. I'm writing a set of parsers, to parse
different kind of configuration formats. The first is an .ini parser.
The code almost works correctly. The only problem I have is that
sections get overwritten if appear multiple times in the .ini content.
[abc]
test = 1
[abc]
xyz = 2
Should result in: array('abc'=>array('test'=>1, 'xyz'=>2))
but instead returns: array('abc'=>array('xyz'=>2))
The logical conclusion is that my zend_hash_find call doesn't work
correctly and is always returning FAILURE. Though I've got no clue
what's wrong. Perhaps someone could have a quick look at the code.
Thanks a lot,
Arnold
