Call php exec function on linux

Question

Few months ago I make small c++ console application on Windows. I need to run exe file over the browser. I use exec php function and everything works fine. Now I trying to do same thing on Linux so that I can put executable file on Linux web server. My linux executable file (inpainting) work when is called from console. But I can't run executable file over exec function.

xampp windows: - this works, i get my results.

<?php
$imagename = $_GET['imagename'];
exec('inpainting.exe' .$imagename); 
echo "<img src=\"./images/img-uploads/ob_img$imagename.jpg\" />";
?>

But how to run it on xampp linux? I try this and results is blank screen.

<?php
$imagename = $_GET['imagename'];
exec('inpainting' .$imagename); 
echo "<img src=\"./images/img-uploads/ob_img$imagename.jpg\"/>";
?>

And I try few more things, but nothing happens. Some people say that exec is bad thing, if someone have other better solution - please share with me. Any ideas? Tnx

I allow all permissions on working folders. I run xampp 1.7.3a on Ubuntu 12.4

Have you tried using the full path to the executable in exec? — Michael, Dec 29 '12 at 08:17
you need a space between the program and the filename, probably what @Michael said would help too. — Get Off My Lawn, Dec 29 '12 at 08:20
Linux can't run Windows' executables. Also, there's a **huge** security hole there. — Corbin, Dec 29 '12 at 08:21
@RyanNaddy "Few months ago I make small c++ console application on Windows." Sounds like he might have uploaded the binary.... — Corbin, Dec 29 '12 at 08:22

@AlexLunix Odd he gave it a `.exe` though. Sounds like it might be two different files. (Probably not though -- I must admit that I tuned out a bit after reading the first sentence, seeing `exe` and looking at the code.) — Corbin, Dec 29 '12 at 08:24
@Corbin Completely valid point though, if they are the same file, that would definitely be a problem. — John V., Dec 29 '12 at 08:25
No, i have to different files. inpainting.exe is for windows, and inpainting is for linux — Rile, Dec 29 '12 at 11:25

This may help, I added the second parameter then did a dump, it should display all the output from the command that was run.

<?php
$imagename = $_GET['imagename'];
exec('inpainting ' .$imagename, $opt); 
var_dump($opt);
echo "<img src=\"./images/img-uploads/ob_img$imagename.jpg\"/>";

I try that, but instead of image I got this: `array(0) { } ` – Rile Dec 29 '12 at 12:21
@Rile I see that you've accepted this as an answer. I'm facing a similar problem. Could you explain how you managed to solve your problem? – asprin Apr 19 '13 at 07:43
