passing multiple parameters from php to shell

Question

I want to run .exe (c++) file by php script. I tried very different combinations of exec command, but still my programs returned -2 (argv<6) or array (?), now I tried to use shell_exec

<?php

$params = array ('nnn.jpg', 'fff.jp2', '300', '300', '50');
$params_string = implode(" ", $params);

shell_exec('demo.exe '.$params_string);
echo 'demo.exe '.$params_string
?>

but it is not working too... I echoed the string I used, and it's just okay

I got it to send parameters properly, but program exits with error caused by write problem. I've changed all perms in target folder to "full control". Maybe there is something with php settings? (xampp on win7 x64)

demo.exe nnn.jpg fff.jp2 300 300 50

any ideas?

ERROR: Exception: demo.exe: no decode delegate for this image format `kush.jpg' @ error/constitute.c/ReadImage/532-5

but as I said before, all goes well through cmd...

问题更多是服务器问题，dar7yl几乎是正确的，问题是apache无法访问位于程序文件中的imagemagick lib ...我不得不将apache用户更改为我的帐户，现在一切正常;）
