Insert PHP code into footer.php

I'm trying to isert this code into my footer.php

if ( ($eventlisturl = get_post_meta( $post->ID, 'eventlisturl', true ) )) {
$eventlistoutput = file_get_contents( $eventlisturl );

$search = array( "$location", "$url" );
$replace = array( get_the_title(), "http://" . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'] );
$eventlistoutput = str_replace( $search, $replace, $eventlistoutput );
echo $eventlistoutput;
}

I've also tried using the footer hook, but in either case the code just prints out on the bottom of my site. Any thoughts? Thanks.
