PHP how to execute a command

Question

I\'m trying to use LibreOffice for converting a spreadsheet to another format, when I execute the command from the console it works fine but when I do it from PHP using exec

Answer 1

I solved this problem with the command below :

exec('libreoffice --headless --invisible --norestore --convert-to pdf --outdir /my/folder /my/file/calc.xls');

Just check rights, libreoffice uses user home folder, If you use default settings for Ubuntu then PHP runs oenter code heren www-data rights and it's home is /var/www/, but default this directory is owned by root.enter code here

In PHP - you can see rigths:

exec('whoami', $arr);
print_r($arr);

In console - You can see your HOME and give correct rights:

su wwww-data
echo $HOME
exit;
chown www-data:www-data /var/www -R
