Umm, no it's not. Static variables have persistence, but are scoped just like normal variables - http://us2.php.net/manual/en/language.variables.scope.php, about 10% down the page, under the header "Using static variables" - "A static variable exists only in a local function scope, but it does not lose its value when program execution leaves this scope." Three simple ways to fix this: 1. Declare $con as a global 2. Return $con from the initialization function, and pass it in as a parameter to all functions that need it 3. Put all these functions into a class, and make $con a member of the class, so it could be referenced by $this->con >From the looks of your code, #3 is really your right answer, as it appears you're trying to create a set of functions that are related, and need to shared common data - you've got yourself an object... Otherwise, if you don't want to go OOP, then go with #2, as #1 is the most dirty way of fixing the problem. :) HTH -James > >> > ie.
