Executing wkhtmltopdf from PHP fails

There were several topics similar to mine, but they did not help me. Perhaps something new will come.

Problem: I cannot execute the PHP wkhtmltopdf form. My main code is: exec('wkhtmltopdf http://somesite.com /home/user/file.pdf');

Now a few things I already checked:

  • the same command works when launched from the console
  • safe_mode is disabled - I can execute commands in PHP, for example it exec('ls');works fine
  • you can find the path to wkhtmltopdf, and I can run the program myself, for example, it exec('wkhtmltopdf -V');works fine and displays version information
  • the output path is writable, it has 777 permissions and exec('wkhtmltopdf -V > /home/user/file.pdf');works fine, it creates a file and puts version information inside
  • running with PHP, has access to the Internet, for example, it exec('wget -O /home/user/file.pdf http://somesite.com')works fine, it extracts the source of the site and puts it in a file
  • replacing exec with passthru, shell_exec, etc. irrelevant

Conclusion: I can execute wkhtmltopdf, I can access the Internet, I can write a specific file, but the correct conversion command does not work and returns status 1.

I am using the latest version of Ubuntu, PHP version 5.3.10-1ubuntu3, version wkhtmltopdf 0.9.9. I tried this also on another machine with the same results.

Any ideas (just ANY) will be very grateful!

Add 2>&1to the end of your command to understand the exact error.

exec('wkhtmltopdf http://somesite.com /home/user/file.pdf 2>&1');
