hmm actually what error did mysql_connect throw?
because if it just fails connecting, it returns false. on the other
hand, if you provide it wrong arguments (e.g. less arguments, or wrong
data type, or whatever) that raises a php error and the function does
not even run.
this is true for most functions which return false on error. the
returning false means there was some error with the action itself, while
php errors are raised when the action can not be executed because of
some error in the code itself.
