when you want to access a variable in nested functions, don't forget that each function depend
of local scope, not main scope.
this don't work
$hello = 'hello';
function a()
{
function b()
{
global $hello;
echo $hello;
}
b();
}
but this works
$hello = 'hello';
function a()
{
global $hello; // here it is
function b()
{
global $hello;
echo $hello;
}
b();
}
and don't forget to declare your variable before using them with global inside a function
