Hey all, I've got some code from someone else I've inherited and need to sort out some problems with. The programmer that wrote it originally was much better than I and programmed a little over my head to say the least. One function that I've come across that has 5 variables as input: function($var1,$var2,!$var2,$var3->cc,$var3->bcc); The question I have is on the 3rd input variable, what does the "!" in front of $var2 do to that variable? Jeff
Looks like it's type casting the variable. To what I don't know...I've never seen '!' used in a function like that. causes a boolean var to be the opposite
!$var = true returnes false Barry -- Smileys rule (cX.x)C --o(^_^o) Dance for me! ^(^_^)o (o^_^)o o(^_^)^ o(^_^o)
