function my_function()
{
    $write = 'hello world';
    $content = apply_filters('the_content', get_the_content());

  1. Not exactly sure what you are trying to accomplish, but it looks like you are trying to prepend something to the beginning of the_content.

    Try this:

    add_filter('the_content', 'se24265_my_function');
function se24265_my_function( $content )
{
    $write = 'hello world';
    $new_content = $write . $content;
    return $new_content;
}

    Most filters will provide a parameter or two for your function to manipulate and then return.
