I am trying to use a php_stream* as a global
(and hence persistent) resource, but gdb detects
a memory leak at the end of the request, and subsequent
calls to the stream say the stream is no longer seekable.
How do I declare a php_stream (opened presumably with
php_stream_open_wrapper) to be a per
I have written a C++ extension for php which accesses
an external .so proprietary data engine.
The extension basically works, but the engine - reliable
when accessed outside php/zend - is generating stream

I have a C++ based php-extension accessing a C++ based non-php .so data
engine, which reads and writes using the open/read/write/close calls in
fcntl.h.
The non-php engine is reliable away from php, but when accessed via the
php extension, it works, but runs into two forms of errors:
a) seek/r
Turns out that even though the missing functions had no impact
in code, they do indeed cause the register functions process
to throw an error, leading to a sigseg fault.
At least it encourages tight and tidy code!

If anyone has come across a similar phenomenon, or can shed light
on the matter, I'd be most grateful.

Hi there,
I've successfully developed a stripped down C++ php class creator,
with private storage, a la Marcus Boerger util.c, and following Jay Smith,
George Schlossnagle et al.
For neater code, I've stripped out function declarations, function entry
tables, class entry etc. into a second .h/.c
at:
http://somabo.de/php/ext/util/
Simple test script below
// written by Andrew Mather - ie: not an authorised test!
// (Does work however - I leave it to you to change the target dir)
$path = "/home/andrew";
$u = new dirs($path);
$upath = $u->getPath
Further to my earlier mail, does anyone have/know of a
working example that demonstrates private data held in
C/C++ and encapsulated within a Php/Zend object for
storage, exposing a Php class, per George Schlossnagle's
recommendation/example?
Cheers,
Andrew.
I'm working through George Schlossnagle's Advanced PHP Programming,
(which I'm happy to plug. Excellent).
Having successfully used C++ to generate extensions (per Jay Smith tutorial)
I am now checking out the facility to store custom objects - packaged private
data alongside the native zend object

I have an external library (C++, .so shared lib) that uses
functions (open, etc) to access local disk resources,
to create a data repository.
I have written a standalone KDE client that affirms that the
library is functioning correctly.
When I try to use a class from that library in a PHP-C++ e

Having got a PHP/C extension .so shared library working,
(courtesy this mailing list), and now also ported a C++
data server to Linux, which could also be a (C++) .so, the
obvious question is:
- can I talk to a C++ library from PHP, either directly or via
a PHP/C extension?

Essence of George's reply:

the SuSE rpm may install it's header files in $foo/php5, but PHP
always expects them to be in $foo/php.
You can manually fix this by editing the executable 'php-config' (use

ps: the example given at http://www.zend.com/php/internals/ makes sense, as
such,
but while the first two command (phpize, ./configure, seem to work, the make
command
throws errors like confetti, based on the lack of php.h, zend.h
