Really weird "global" bug

[eluser]richthegeek[/eluser]
Getting a really odd global bug..

In my "view":

Code:

print_r( $data );
print_data();

In my misc_helpers file:

Code:

function print_data()
{
   global $data;
   var_dump( $data );
}

products the $data array from the print_r and NULL from the var_dump in the print_data() function.

This also occurs if I put the function codei nthe view file... anyone got an explanation?
