returning Integer array to PHP from C

[Dheeraj Joshi]

Hi... I have got a problem.

I try to return a integer array from C tp PHP but unable to get the values back..I am using SWIG to integrate C and PHP.

My .c looks like.

int arr[2];
int *arr_ret()
 {
     arr[0]=2;
     arr[1]=4;
     return arr;
 }

My .i looks like:

%module example
 %{
extern int arr[2];
%}
 extern int arr[2];

My php is:

<?php

include("example.php");

$t = array(get_time());

print_r $t;

var_dump($t);

?>
----------------------------------------------------------------

Your PHP doesn't call the arr_ret() method.

[Dheeraj Joshi]

Sorry mark...... That was some other function.

My PHP looks like,

<?php
include("example.php");
$t = array(arr_ret());
print_r $t;
var_dump($t);
?>

I've no idea - you might better asking on a SWIG mailing list / forum.

Mark.

P.S. Have you tried writing a PHP (zend) extension to wrap the C functions? It's pretty easy.

I read introduction to ZEND..

Dont know why.. But it scared me.

C array in PHP via SWIG

Hi... Does anybody know, how to manipulate the C arrays in PHP via SWIG?

Since in C

return arr;

return the address not the value. How this can be handled in PHP?

I read SWIG documentation.. But not much helpful.

I have merged your threads because they are largely on the same topic.

Like I said previously, you'll have more success if you ask a question on the mailing lists.

Mark.

[Dheeraj Joshi]

I already mailed to mailing list...

Mail archieve is not getting updated from 21st Aug.. So i dont get their mails.. I dont know why...

And we are running short of time.. Need some work arounds..

The mailing lists seem to have had a lot of use this month.

Do not use pointers. That will return address only, not value.
Try this: (not sure if it will work)

int arr_ret()
 {
     int arr[2];
     arr[0]=2;
     arr[1]=4;
     return arr;
 }

I you can't change C code, change php like:

$arr = "";
&$arr = arr_ret();
print_r($arr);

[Dheeraj Joshi]

Without taking pointers it works fine..

But C code belong to some other organization and i dont have permission to change it..

But i did a work around for that problem..

Now i am able to call C functions in PHP.. HURRAY....

can you please give me the solution for the above mentioned problem

[Dheeraj Joshi]

Use SWIG to wrap c data structures and methods as PHP variables and methods.
