Find out whether string has date in it

I have a string "scbdemo2016-10-21:getlastweekReadBooks4795".
How to find out the above string has date in it and to validate the date is current day date.

Answer Source

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.


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