If it contains spaces or other shell special characters, you may need to escape $doxyFile with escapeshellarg() first.

Edit for the record, it was a permission problem. See the comments for details.

It is not that the commad seems correct see the dump:command: doxygen /home/guillaume/Documents/doxygen/Doxyfile-jmk <br />output: array('0'=>'Exiting...')I think doxygen doesn't like to be executed via php...

Can you access the file directly from PHP using `fopen()` for example?
Pekka  2010-01-06 15:40:21
Yes, file_get_contents($doxyFile) returns me the content of file.
toddoon  2010-01-06 15:47:10
Maybe stderr doesn't show up in $output. Can you try `exec($command." 2>`
Pekka  2010-01-06 15:54:22
The result is:<code>array([0] =>'Warning: the dot tool could not be found at /home/guillaume/Documents/doxygen/jmk/dot'...[1] =>'Failed to open temporary file /home/guillaume/Documents/doxygen/jmk/doxygen_objdb_8350.tmp'...[2] =>'Exiting...'...)</code>

Ahh, that's better. Can it be that either PHP or Doxygen are not allowed to write into that directory? Can you make that directory writable or tell Doxygen to put its temporary files elswhere?
Pekka  2010-01-06 16:02:38
So i think I have the answer: the tool could not be found perhaps the environment var are not loaded... I will search in this way :-)
toddoon  2010-01-06 16:04:37
Oh yes it was a persmission problem, I do chown -R www-data: in the directory and now it works. I congratulate you :-).
toddoon  2010-01-06 16:07:24
All right, congratulations!
