Question

PHP on IIS using imagemagick

Asked by: StephenGobin

I am trying to convert a pdf to a jpg with php. I have installed ghostscript and imagemagick. On the webserver I can run the following code from the command prompt successfully.

C:\ convert a.pdf a.jpg

When I try it in PHP I get the folloing error.

CGI Error
The specified CGI application misbehaved by not returning a complete set of HTTP headers.

Thanks for any help.

<?
	exec("convert sample.pdf sample.jpeg");
?>

Try to output a set of correct headers, such as:
print "HTTP/1.0 200 OK\n";
print "Content-Type: text/html\n\n\n";

And see if it solves the problem.

Are you using IIS or apache? This is a common problem/bug on IIS.

 

by: StephenGobinPosted on 2009-01-08 at 09:23:57ID: 23327308

I am using IIS.

I tried what you suggested and I also tried the attached code.

Any other ideas? I don't need any information sent back to the php script, I just want it to run the command.

<?
	header("HTTP/1.0 200 OK\n");
	header("Content-Type: text/html\n\n\n");
?>

Ok I added this code and now the CGI error has gone away, but now it says access denied.

<?
	echo "<head>";
	flush();
?.

Hi,

Here is some information:
http://answers.google.com/answers/threadview/id/264771.html

It sounds like IIS is causing the permission problems, as they elaborates more in the discussion, however at the end no immediate solutions were found.

Another suggestion may be to try apache as oppose to IIS?

Goodluck :)

In order for this to work, the user running PHP (typically the IUSR or similar account) needs read and execute access to the directory holding the executable, read access (and possibly execute) to any supporting files used by the executable, and modify access to the directories in which the work is being done.  There may be other permissions involved as well...exec'ing from IIS is a complicated topic.
