Code

$ruleString =
    "FREQ=WEEKLY;COUNT=2;DTSTART=20200518T170000;DTEND=20200518T172000;INTERVAL=1;BYDAY=MO,TU,WE,TH,FR,SA,SU";

// $startDate = new \DateTime('2014-06-17 04:00:00');
$rule = new \Recurr\Rule($ruleString);
$transformer = new \Recurr\Transformer\ArrayTransformer();

dd($transformer->transform($rule));

Output
