scope after register globals turn off
is not so clear !
just to clarify things to newbie
function createAglobal(){
global $var
$var = "value";
}
//you MUST call the function to use the global $var
createAglobal();
echo $var; //you will get value
//if you use echo without calling the function you will
// get Undefined variable: var error i know it might be
// obvious for some but i think a lot of people dont
// think that might be there problem
function readAglobal(){
global $var;
echo "this it my global $var";// will work
}
createAglobal();
readAglobal(); //will echo this is my global value
i do hope you will find this info helful
best regards
