How can I check if a function is already set? Can is use isset? What would be the syntax to see is a function is already included in the script included named dbconnect()??

Thanks

Just click the link I provided in my response, and about the 2nd or 3rd sentence on that manual page answers your question.

PHP interprets everything as a boolean (when nessecary), so it doesn't matter.
