Question

I m using SWIG to make my C code work on php...But I don t figure out how to write a good interface based on my C code to pass to SWIG.Can somebody help me? The link to see what my C code looks like is this one : http://www.pastie.org/1739618 Thanks a lot for your help

Answer 1

You should move your function prototypes to a separate header file. SWIG can process that and generate the required stuff for you. You can follow the SWIG tutorial and specifically pay attention to the section SWIG for the truly lazy which shows how you can avoid having to maintain a separate SWIG interface file.

参考SWIG和PHP网页,你应当能够做事。注:SWIG不支持PHP4。

也许你可以首先尝试像以下内容一样的内容,并将之作为对<代码>swig的投入。指挥:

/* optim_wizard_5.h */

#ifdef SWIG
%module optim_wizard_5
%{
#include "optim_wizard_5.h"
%}
#endif

/* Function prototypes to define later */
void *getCpc(void *ptr);
float getCpc_max(float *arg);
char *do_web_request(char *url);
size_t write_data(void *buffer, size_t size, size_t nmemb, void *userp);
float request_cpc();

Answer 2

在使用SWIG时,往往不使用多种语言:

Don t throw exceptions outside of the interface you want to expose to SWIG
Don t return or require as parameters, raw C-arrays in the interface you expose. (Wrap them in structures preferably)
Write SWIG interface files that include the header files you want to expose in your interface to PHP. Don t embed SWIG #ifdefs in the C code itself...
