[wp-hackers] Changing two variables listed in apply_filters hook

[Robin Adrianse]

function test_function( $var1, $var2 ) { }
add_filter( 'filter_name', 'test_function', 10, 2);

The last argument in add_filter is the magic -- it's how many arguments your
function is set up to receive. The 10 is just the default for priority.
