There is a third required argument to this function, if you pass just the 2 listed here the function will return no data.
The third argument is the number of results you want, if you want everything simply pass count($OPTSARRAY) as arg3.
<?php
$opts = array ( "AVERAGE", "--start", '-1d');
print_r(rrd_fetch('./rrds/file.rrd', $opts, count($opts)));
?>
