Hmm i was checking out a pear class, what about the variables within a function ? like function foo($name) { if ($name) { } } or foo($name) { if (isset($name)) { } } it uses isset on variables coming outside the function

Those examples don't make much sense. Without a default value, if foo() is called without a parameter, then it'll cause an error. So, obviously $name is going to be set. So isset() will always be true. if($name) is a valid check, I guess, since an empty string or zero could be passed and cause that to fail. It'd make more sense to set a default value for $name or check for an actual value instead of just seeing if (boolean)$name is TRUE or FALSE. -- ---John Holmes...
