Here is your code, but it only works with string that has : character, anyways

function checkdata($date, $format)
{
    $format=strstr(preg_replace("/[a-zA-Z]+/", '',$format),":",true);
   // date_default_timezone_set('UTC');
    $d = DateTime::createFromFormat($format, $date);
    if($d && $d->format($format) === $date) {

        return true;
    } else {
        return false;
    }
}

$data="scbdemo2016-10-21:getlastweekReadBooks4795";

if(checkdata($data,'Y-m-d'))
echo "Yes";
else
echo "NO";

Easily done with regular expressions:

$isToday = stringDateToday("scbdemo2016-10-21:getlastweekReadBooks4795");

function stringDateToday($string) {
    $reg = "/\d{4}-\d{2}-\d{2}/";

    $date = new DateTime();

    preg_match($reg, $string, $matches);

    if (isset($matches[0])) {
        return $matches[0] == $date->format("Y-m-d");
    }

    return false;
}

stringDateToday() will return true if the date in the string is today. The date can be anywhere in the string.

EDIT:

As suggested in the comments, you may want to change new DateTime() to new DateTime('now', new DateTimeZone('Europe/London')) to specify timezone.
