an example that shows the usage of this method ( tested in php version 5.6.30 )
class Rrd{
public function getData($id , $start , $end)
{
$step = 300 ;
$rrdFile ="/path/to/file/'.$id.rrd";
try{
$options = ["--start", $start , "--end", $end ,"-- step",$step,"DEF:out=$rrdFile:name:AVERAGE", "XPORT:out:test"];
$result = rrd_xport($options);
$datas = $result['data'][0]['data'];
foreach($datas as $data => $value){
if( is_nan($value) === true ) $value = 0 ;
$output[] = [$data=>$value] ;
}
return json_encode($output);
}catch (Exception $e){
dd($e->getMessage());
}
}
}

A small example of connecting to an rrdcached daemon (This one running on localhost, but works across network as well) and getting in and output bits from an interface.
$options = array(
'--daemon', '127.0.0.1:42217',
'--start', time() - 3600,
'DEF:in_oct=rrdfile.rrd:INOCTETS:AVERAGE',
'DEF:out_oct=rrdfile.rrd:OUTOCTETS:AVERAGE',
'CDEF:in_bits=in_oct,8,*',
'CDEF:out_bits=out_oct,8,*',
'XPORT:in_bits',
'XPORT:out_bits'
);
$result = rrd_xport($options);
var_dump($result);
