[PHP-DEV] linking against ststic librarys
Hi, is it possible to create an extension that links against a static library. If it is could someone point me to an extension that does this, or explain how to do it. Thanks Tony -- PHP Development Mailing List http://www.php.net/ To unsubscribe, visit: http://www.php.net/unsub.php
[PHP-DEV] updating php_error messages
Hi, I have noticed in the TODO file in head one of the items is: * Change PHP error messages, so that they point to pages or sections in the PHP Manual. I have a few weeks of spare evenings coming up so if anyone wants me to I'm happy to wade through and make the changes. As far as I can see it's just a case of changing php_error to php_error_docref and adding NULL TSRMLS_CC as the first argument. I don't have karma to do this so either I would need it or I could supply patches. Tony -- PHP Development Mailing List http://www.php.net/ To unsubscribe, visit: http://www.php.net/unsub.php
[PHP-DEV] Freeing memory
Hi, I am getting the following output from a php script that calls an extension I am writing (I have compiled the extension with --enable-debug) /home/phpcvs/php4_head/ext/pipe/pipe.c(245) : Freeing 0x0822568C (12 bytes), script=test.php /home/phpcvs/php4_head/ext/pipe/pipe.c(244) : Freeing 0x0822564C (12 bytes), script=test.php where lines lines 245 and 244 are: MAKE_STD_ZVAL(read); MAKE_STD_ZVAL(write); Does this mean that I need to free the memory from the zvals when the script exits, or is this just information?

Re: [PHP-DEV] Freeing memory
The whole picture is that i want to control a child process completely
from within php. A bit like popen or proc_open but with 2 independent
pipes to the child's stdin and stdout that I can read and write to. So
I'm basically wrapping the c functions pipe(), dup2() and friends. Once
I have it all working I will offer to add the functions into the pcntl
extension if they're wanted.
Anyway the code in the pipe function that was giving me the warnings is
as follows:
PHP_FUNCTION(pipe)
{
pipe_r_le_struct *st_pipe_r;
pipe_w_le_struct *st_pipe_w;
zval *read;
zval *write;
int pipe_fd[2];
if( pipe(pipe_fd ) 0 ){
php_error( E_ERROR, Could not create pipe );
}
st_pipe_r = emalloc( sizeof( pipe_r_le_struct ) );
st_pipe_w = emalloc( sizeof( pipe_w_le_struct ) );
st_pipe_r-fd = pipe_fd[0];
st_pipe_w-fd = pipe_fd[1];
MAKE_STD_ZVAL( read );
MAKE_STD_ZVAL( write );
ZEND_REGISTER_RESOURCE( read, st_pipe_r, le_pipe_r )
ZEND_REGISTER_RESOURCE( write, st_pipe_w, le_pipe_w )
array_init( return_value );
add_assoc_resource( return_value, read, Z_RESVAL_P( read ) );
add_assoc_resource( return_value, write, Z_RESVAL_P( write ) );
}
If i use FREE_ZVAL() at the end of this function I can get rid of the
warnings but I would guess this is the wrong place and it should be
taken care of in a cleanup function when the request has finished.
Please excuse me if I am missing something obvious here, as you may
guess I'm still finding my feet writing PHP extensions.

Actually zval_ptr_dtor() is probably more suitable.
In any case, is this zval something you keep locally in your extension or
are you returning/adding it to the engine's symbol table? If so, the engine
should take care of the memory automatically as long as you've done
everything correctly.
Maybe you should explain in more detail what you're doing.

Re: [PHP-DEV] Freeing memory
Hi Wez, I wrote a pecl extension called ecasound which interacts with an audio processing library. Now the way that ecasound is written will change in future versions and will have a fully interactive mode, all other implementations (perl, python c++ etc) have been re-written so that they open up a couple of pipes, fork and then exec ecasound in the child process so using the interactive mode instead of linking against the librarys. What I would like to do is to make the PHP implementation work in the same way as all of the others but of course PHP does not yet have full 2 way communication with a child process. I agree that extending proc_open may be the best solution but while I would be willing to do the work I'm not sure that I can at the moment. Working with processes etc in c is fairly new to me and so are PHP extensions so trying to extend someone else's function that already looks fairly complex may be beyond me at this time (also I do not know anything about programming under win32). Maybe I'll take another look though as If this would really be the best way to implement the functionality I need then it may be a good learning exercise :) Tony On Sat, 2002-11-09 at 19:52, Wez Furlong wrote: Hi Tony, What kind of things are you planning to do? proc_open seems ideal to extend for this purpose, and works on win32. --Wez.

Hi Brian,
I can't help with your specific problems but there are a couple of
shortcuts you can use in your module.
You can get the string length of your arguments as they are passes in,
see below.
Also there are macros for returning values which I believe are the
preferred way of doing things. I have made the change in your code below
to show how to get the string length passed in.
you have 2 functions for returning strings :
RETURN_STRING(char *s, int dup)
and
RETURN_STRINGL(char *s, int l, int dup) if you know the length of the
string.
int dup, should be 1 unless you estrdup or emalloc the string.
these 2 functions seem to have aliases RETVAL_STRING and RETVAL_STRINGL
I'm not sure which version is preferred.
see for further info

[PHP-DEV] library calls from within php functions
Hi, I am working on an extension that makes use of the pipe, read and write library calls on a linux platform. When I try to put this line read(fd, buf, 1024); inside a php function ( PHP_FUNCTION(read_pipe) ) it fails to compile with the following warning: called object is not a function. If I move the same line into a standard c function it compiles without error. So my question is, is there some problem trying to make library calls from within php functions? although other calls seem to work fine.

Thanks for the fast reply Wez,
There's not much we can tell you about this unless you post the
rest of the lines of that function.
See below for the code
Perhaps you did not include php.h ?
Yep thats there, I used exec_skel to create the basic module.
Note: always prefer this:
read(fd, buf, sizeof(buf));
to this:
read(fd, buf, 1024);
Thanks, done that.
OK, what I'm trying to achieve is basically wrapping pipe, read and
write so in a php script I can create 2 pipes, fork the process using
pcntl_fork() and have 2 way non blocking communication with more control
than proc_open()
I have so far written this function that creates the pipe and returns an
array of the pipes descriptors:
PHP_FUNCTION(pipe)
{
pipe_r_le_struct *st_pipe_r;
pipe_w_le_struct *st_pipe_w;
zval *read;
zval *write;
int pipe_fd[2];
if(pipe(pipe_fd) 0){
php_error(E_ERROR, Could not create pipe);
}
st_pipe_r=emalloc(sizeof(pipe_r_le_struct));
st_pipe_w=emalloc(sizeof(pipe_w_le_struct));
st_pipe_r-fd=pipe_fd[0];
st_pipe_w-fd=pipe_fd[1];
MAKE_STD_ZVAL(read);
MAKE_STD_ZVAL(write);
ZEND_REGISTER_RESOURCE(read, st_pipe_r, le_pipe_r)
ZEND_REGISTER_RESOURCE(write, st_pipe_w, le_pipe_w)
array_init(return_value);
add_assoc_resource(return_value, read, Z_RESVAL_P(read));
add_assoc_resource(return_value, write, Z_RESVAL_P(write));
}
This function appears to work as expected
and now I'm trying to write functions that will read and write from the
pipe. So far I have this, it isn't finished as you will see.
PHP_FUNCTION(pipe_read)
{
pipe_r_le_struct *st_pipe_r;
zval *read;
zval * res;
char buf[1024];
if (zend_parse_parameters(ZEND_NUM_ARGS() TSRMLS_CC, r, res) ==
FAILURE) {
return;
}
ZEND_FETCH_RESOURCE(st_pipe_r, pipe_r_le_struct *, res, -1,
pipe_r, le_pipe_r);
if(!st_pipe_r) RETURN_FALSE;
read(fd, buf, sizeof(buf));
}
I was just testing that it still compiles and it fails on the
read(fd, buf, sizeof(buf)); line. with the error
called object is not a function
As I mentioned if I move that line into a c function it compiles fine.
Thanks
Tony

Re: [PHP-DEV] Sound API for php
For the 'web-side' of things - could these conversion function be used, to convert files on the webserver? Or even something like: song.wav - convert_to_mp3 - stream_on_socket song.mp3 - convert_to_windows_media - stream_on_socket There's no reason why you couldn't convert files on the webserver, it will convert files that it sees on it's local file system. Ecasound will not stream over a socket (AFAIK). It's standard out is a soundcard via either ALSA or OSS drivers. It's an interesting point though and the guy who wrote and maintains the library is pretty good at adding functionality. As far as windows media goes, it's not a supported format and I would guess it never will be. And can it read mp3 or whatever 'about' information is stored in the audio file? Ecasound doesn't have this functionality, although this is something I have thought about and would be looking to implement it at some point. I'm sure it can't be that hard to read in the file headers.

Thanks for the suggestion to put this into Pear. I have subscribed to the dev list and I'll see what they think :) Regarding the API, I am planning 3 sets of functions. 1) Ecasound functions that simply wrap the Ecasound Control Interface. I have named these: eci_init(); eci_command(); eci_error(); etc, I really want to use this naming convention as it is exactly the same as the interface available in perl, python etc. 2) Higher level functions for manipulating sound files. These are what I would expect to be of most interest to others. As I mentioned before scripting ecasound is tricky so simple functions to play or convert files would be useful. I am planning to name these with the audio_ prefix, ie audio_playfile(); audio_convert_file(); audio_new_chain(); Is this a good idea, I thought of the audio_ prefix to clear up any confusion with other functions, but it will mean some function names will be a little long for example, audio_chain_set_position(); is this too long? 3) will be midi functions,this is a long way off yet so I haven't given it too much thought yet. Also it is likely to be a separate module as it will need to link against a separate library and I can't think of any PHP modules that link against 2 libs. One last question. I'm sure I read somewhere that the PHP licence is not compatible with the GPL. Is this true? If so what do I need to do is a simple agreement from the ecasound maintainer enough or will he need to release it under the PHP licence as well?

array_swap($array, $key1, $key2), where keys can be either index or
assoc and array content can be any combination of string, long, array
and object.
