Are you changing your active directory to /var/www/html/nubuilder/db in 
your shell script first?  It looks like your shell script is getting a 
listing of that directory and then trying to execute your PHP script in 
that directory which is failing because the parent process that called 
the PHP script is not currently in the directory where the PHP script is 
trying to find the files it is supposed to be working with.  See where 
it says, "failed to open stream: No such file"?
