How to&Answers:

You should take a look at the System program execution section of the manual : PHP provides several functions that can be used to launch external commands / programs, including :

  • exec() — which can store the output of the command in an array
  • shell_exec() — which returns, as a string, the output of the command
  • system() — which echoes the output of the command

Answer:

To create a pdf from php(in linux) you must use a wrapper.

$cmd = '/usr/bin/xvfb-run --server-args="-screen 0, 1920x1080x24" /usr/bin/wkhtmltopdf http://google.com /tmp/google.pdf';

exec($cmd);
