Exec() function

[link7722]

I am usinig exec() function to execute 2 shell commands($command1 and $command2) in my Linux server

if ($_POST['database'])
{
$command = "mysqldump --opt -u root -pgabriel13 teo > /var/www/teo/dbbackup.sql";
exec($command);
}
else if ($_POST['configuration'])
{	
$command2 = "cp -R /var/www/teo/ /var/www/bck/";
exec($command2);
}

Although command1 is executed as expected, command2 doesn't seem to do anything and i don't get any error.Of course if I copy and paste

cp -R /var/www/teo/ /var/www/bck/

to my Linux shell the command is executed OK.Any help ?

Thank you

Are you sure that the Apache user has sufficient permissions to read /var/www/teo and write /var/www/bck?

Exec() commands are executed by that user.

You are right.It was a permission issue.

Thank you very much.
