Does anyone know if there is a builtin function for checking the
formatting of an incoming date to verify it is YYYY/MM/DD. I know how
to convert between formats but want a quick way to check an incoming

I normally provide dropdown fields for each (except the year which is a
text-field) and put it together how I need it. Validate each part
separately and you're off and racing.
If you accept any date you'll probably have to split it up first but the
principles will be the same.
$date = '0000-00-00';
// if they didn't use exactly two dashes? invalid
if (substr_count($date, '-') !== 2) {
die("Invalid date");
}
list($year, $month, $day) = explode('-', $date);
if (strlen($year) != 4) {
die("Invalid year");
}
and so on.
