Well I'm creating a nested hash that I want to return ultimately, so at my first recursive step I pass return_value as the hash to be filled. However at various steps in the recursion I add elements to the hash that overwrite default values. So my question is whether during this recursive process does the garbage collector run when I overwrite a hash entry? Hope that clears things up.

I ask because I watched my memory consumption climb to over 500MB and all I use is MAKE_STD_ZVAL( newVar ) and insert into some depth of the recursion initially stored into return_value for the calling function. My initial assumption was that indeed this stuff is garbage collected... but maybe I'm doing something wrong if this is collected at the moment of overwrite and I'm seeing such massive allocations using top.

I don't see why not provided you are able to compile PHP. As long as you can compile PHP your extension "should" compile into a Mac native binary. All you should need to do is create wrapper functions around your current library to make them accessible via PHP in your extension. If you're like me you will compile this directly into the PHP binary itself, and then I don't think you will need any other binaries. Alternatively, since you are comparing this to window's DLLs I think you can compile as a shared library, but I don't know much about that route and wouldn't advise it since as far as I know it runs like CGI.

You would think so, but on further thought, if that were the case you wouldn't be able to store compressed data from gzip in a string because the null bytes everywhere would interfere. Also, as I said, ZVAL_STRING suggests that this is so... since when you use it to set a zval container to a string it saves the length as strlen( passedString ), rather than strlen( passedString ) + 1, also the memcpy then uses this length to copy the string if you set the copy flag to true.

[PHP-DEV] Probably a simple answer...
zval containers that are of string type don't seem to hold a null terminating character, but rather directly store the length of the string - I note this because of how the ZVAL_STRING macro works... My question then is what is the best way to compare two strings in a zval?

I wrote this extension a while back, but I never released it since I didn't follow coding style and it was my first forage into extension coding for PHP. It should be what your looking for though for the most part... the function of usefulness is: get_function_call_stack() which will return an array with the call stack for the current function which includes the calling file, funcion and line number. Use a print_r() on the results to get a better idea. Please don't flame me for not releasing or following coding style.

Re: [PHP-DEV] The PHP Platform
Hey all, I'm just doing a general followup to say how much I love the PHP engine. I find it extremely fast for development and I love that I can integrate C extension modules when time is a huge factor. While PHP seems to be moving into the shadows here where I work I find that I love it more and more personally and is my favourite engine for doing just about everything. I use it for the web and for shell scripting. Most of all I love that something like this can be free, since in my spare time I like to code for a MUD, which doesn't make me any money, but which I find very satisfying. Kudos to all the PHP contributors.

Re: [PHP-DEV] object refrences (POSSIBLE MAJOR BUG)
My apologies... this examples better clarifies your point and I must admit
that it is rather strange behaviour :) And I think I forgot that PHP does
do deep copies, probably because I'm so used to writing wrapper objects
with references to my real objects so I automate shallow copies.

The above quote dereference involves an intermediate method, the one
described in the example below uses an object which is currently
supported.

As far as references go... I believe when you copy an object it is a
shallow copy, in otherwords, the object is copied, but not its members.
This behaviour is preferrable as far as I'm concerned. If you want a
deep copy try doing the following:
$foo = new foo();
$fee = unserialize( serialize( $foo ) );
That should provide a nice quick, clean solution for what you want while
not incurring the overhead most programmers would rather skip on every
object copy.
Cheers,
Rob.

[PHP-DEV] Finding key in a hash...
I am trying to determine if a key exists in a hash that has been passed
to my function. I couldn't find much information on finding how to do
it, but from greping the source I managed to come up with the following.
Problem is it doesn't work *heh*. All I want to do is check whether the
key exists or not and act appropriately. My code compiles fine, but the
zend_hash_exists() test always returns false. The A facsimile of my code
follows:
---
ZEND_FUNCTION( foofunction ){
zval **paramHash = NULL;
zval *aHash = NULL;
if( ZEND_NUM_ARGS() != 1 ||zend_get_parameters_ex( ZEND_NUM_ARGS(), ¶mHash )
== FAILURE ){
WRONG_PARAM_COUNT;
}
aHash = *paramHash;
if( zend_hash_exists( aHash->value.ht, "foo", sizeof( "foo" ) ) ){
//
// Do something here.
//
}
else{
//
// Do something else here.
//
}
}
---
In my PHP code I have the following:
---
$aHash = array();
$aHash['foo'] = 'fee';
foofunction( $aHash );

Rob.

[PHP-DEV] Re-entrant PHP
I mostly don't keep up with the bulk of the PHP threads; however, I did a pretty thorough scan of them to find information about re-entrancy and didn't find anything to answer my question. So here goes... I was wondering if there were any plans to make php_mod re-entrant in any way or if there were any comments on how difficult this task would be. I see the advantages of re-entrancy being that my source code wouldn't need to be reloaded every single time a page is loaded; much of the data would already be in memory with respect to properties and caching; I could have a global persistent cache for some of my data versus saving to a database or shared memory location for subsequent page hit retrieval. Mostly I just don't want my source code re-parsed and loaded on every hit since that is a large overhead once you get into several layers of abstraction.
