I am trying to use pdftk through PHP. It works perfectly through the terminal, and some other commands work with PHP. For example:
echo 'PWD: ' . shell_exec('pwd') . '<br>';
echo 'LS: ' . shell_exec('cd processes && ls') . '<br>';
echo 'PDFTK: ' . shell_exec('/usr/bin/pdftk --help');
returns the following:
PWD: /opt/lampp/htdocs/WebApp LS: auto_complete_test.php .... other files I have PDFTK:
I cannot get any commands involving pdftk to work through PHP, and I have run out of ideas. Any help or suggestion is greatly appreciated.
