Topic awaiting preservation: Can you set a variable so it can be used through all functions? (Page 1 of 1)

Just a quick question.. Is there a way to do it, rather then declaring a global variable in the functions you need, set them so they can be used through all functions?

you can define your own constants (however once defined they can not be changed like a normal variable, they can just be redefined). I use this method for things like DB_NAME etc with MySQL and other site constants.

You should also be able to assign new variables to the $GLOBALS superglobal array but I haven't tried this.

The third thing to look into is passing by refrence.

You may want to look at why you need to do this before finding a solution. There's a lot of good reasons you want to keep variables within their scope.

Thanks for that, yeh your right, its probalby unneccesary =/

yeah, needing a global in every function, that is not a constant, is definatly a code smell!
