[Thu Nov 03 14:47:49 2011] [error] [client 94.145.177.221] PHP Notice:  Use of undefined constant sd - assumed 'sd' in /var/www/_im.php on line 24

Here is the code

$base = $_SERVER['DOCUMENT_ROOT'].'/';
$src = $base.'invoice.pdf';
$dst = $base.'invoice.png';

$syntax = '/usr/local/bin/convert -debug coders -log "%u %m:%l %e" '.$src.' '.$dst;

echo $syntax;

exec($syntax);

is_file($src) returns true

Answer 1

你应该叫convert与-debug coder （而不是coder- S）。

Answer 2

If you are unable to locate your webservers/vhosts error.log this can oftentimes help to figure out some problems:

 print `sh -c "/usr/local/bin/convert -help" 2>&1`;

(Except it's blockend via safe_mode and open_basedir as well. But you would have found out with a PHP warning, unless you had turned them off.)
