But it's the same answer ;-)
If you want to be completely warning-and-notice-free, you need to define
the variable before accessing it:
// this will give a notice
echo $undefined_var;
// and this won't
$define_var = 'some data, or simply put "null" here';
echo $defined_var;
The same holds true for array indices:
$test_array = array('One', 'Two', 'Three');
// this will give a notice
echo $test_array[3];
// and this won't
echo $test_array[2];
// and this won't as well
if (array_key_exists(3))
echo $test_array[3];
Get the idea? IMHO it's complete overkill with PHP to predefine variables
since they're auto-initialized with NULL when used first. These notices are
only for the development cycle, to aid us in spotting a problem where you
expect some data to be there, but it aint because the variable name has
been mistyped...
