I need to get the memory usage of the current process in C. Can someone offer a code sample of how to do this on a Linux platform? I'm aware of the cat /proc/<your pid>/status method of getting memory usage, but I have no idea how to capture that in C. BTW, it's for a PHP extension I'm modifying (granted, I'm a C newbie). If there are ...

I am thinking of writing a PHP extension library that will use the memcached library. It is trivial to simply link my library to the memcache shlib. However, I am not sure what will happen if my (extension library) user already uses memcache on his/her website. My questions are: Is it possible to have (possibly different versions) of...

I compiled some PHP extention libs (in C/C++) a while back, on my XP platform. I have now moved the sources to my Ubuntu box, and want to build the libs for use on my Linux box.

I need to list all PHP extensions that's required by a given code base. What would be the best way to tackle this problem? My initial thought is to write a script that goes through all files and find all functions and compare them to a given extension/function database. Any other suggestions? Update: I already did some Bash script w...

I need to learn how to develop PHP extensions. So, I assume I have to refresh my CPP skills (or is it C?). What IDE should I use (auto-completion, object browsers etc). I plan to develop on Ubuntu 32. Is there a good book or good website I can learn from? ...
I have a suite of PHPUnit tests for my extension, and I want to run them as part of the extension's Hudson build process. So I want to run PHPUnit specifying the extension library to load at runtime, but I can't figure out how to do this. My directory structure is as follows: /myextension.c /otherextensionfiles.* /modules/myextension....
Hi guys, I am developing a php extension that require the use of opengl. I tried to initialize the library with glutinit; it works in CLI environment but when I tried on browser it doesn't seem to execute the code. The code is actually executed on the server side. It is part of a process to extract features from an image, and the serv...
I have a C++ object, Graph, which contains a property named cat of type Category. I'm exposing the Graph object to PHP in an extension I'm writing in C++. As long as the Graph's methods return primitives like boolean or long, I can use the Zend RETURN_*() macros (e.g. RETURN_TRUE(); or RETURN_LONG(123);. But how can I make Graph->ge...
Hi, I've been tasked to create a PHP app which accesses an existing PostgreSQL database. This is my first time working with Postgre, not to mention the PHP has already been installed in the Linux box on which the app is supposed to run. I have no experience setting up this stuff, I just code. My question is that I can't seem to get the ...
This new language called Vala, which is said to be C#-like and supposedly easier than C++ or C, compiles down into C on Linux with the GCC compiler. Sounds great. Now I want to use it to make a PHP extension module so that slow PHP code can be made in Vala and imported into PHP as a function. How do I accomplish this in Vala? Is it eve...
In PHP 5.3 is there a way to rename a function or "hook" a function. There is the rename_function() within "APD" which has been broken since ~2004. If you try and build it on PHP 5.3 you'll get this error: 'struct _zend_compiler_globals' has no member named 'extended_info' This is a really easy error to fix, just change this line: ...
I need to have my PHP extension return an array of objects, but I can't seem to figure out how to do this. I have a Graph object written in C++. Graph.getNodes() returns a std::map<int, Node*>. Here's the code I have currently: struct node_object { zend_object std; Node *node; }; zend_class_entry *node_ce; then PH...
I have written some C/C++ extension modules for PHP, using the 'old fashioned way' - i.e. by using the manual way (as described by Sarah Golemon in her book). This is too fiddly for me, and since I am lazy, and would like to automate as much as possible. Also, I have used SWIG now to generate extensions to Python, and I am getting to li...
