Question

I’ve been trying to run this php code on CentOS:

<?php

$command = "diff file1 file2 > file3";
exec($command, $output, $error_code);

if ($error_code != 0) {
    echo "Error: $error_code";
}

?>

And it always echoes “Error: 1”. Error 1 is “Operation not permitted” http://www.pegasoft.ca/resources/boblap/99_b.html. It looks like apache has no permissions to do certain things, right? How can I fix that?

Oh >____<

I had this line at the end of my script:

exec("rm -f /var/local/out/upload/example_word/word/diff.diff");

The file was created and then deleted… That’s why I could never see it. Sorry.
