pdfsig not run in apache php shell_exec
Hello. My system is Linux Mind 19, apache 2.4.29, php 7.0, pdfsig 0.62.
The pdfsig working good in command line.
But if it is run in apache /php /shell_execute then i get error:
Internal Error (0): couldn't find default Firefox Folder Segmentation fault
(pdfsig -h and pdfsig signed.pdf command too.)
php code:
<?php
....
$out = shell_exec('pdfsig signed.pdf 2>&1');
....
?>
It is a web server, not installed firefox browser. Apache run by "www-data" user. The "/home/www-data" folder not exists.
Thans!
