mySQL question

[mvolmar at fruitlands.org (Mike Volmar)]

Permission problem solved.

I had to
1) create a user at localhost (poorly explained in my php/mysql book; but well
explained in the O'Reilley mysql book)
2) make an identical username in linux
3) then recreate database on the linux box, which I had simply copied to
there; for some reason this made it read only despite changing property
permissions to 777.

Thanks for the help.

====================
Problem:

Line of code:

$num_results = mysql_num_rows($result);

throws an error on linux but not on windows machine.

error=Warning: Supplied argument is not a valid MySQL result resource

Code runs fine on php-triad in windows but mySQL under redhat 7.3 throws the
error.
