Stuck on checking for matching dates

Sorry but I'm stuck on checking on validating dates and I'm hoping one of you will be able to help me.

https://teamtreehouse.com/library/crud-operations-with-php/creating-records/validating-user-data

index.php 
<?php

function valid_sql_date($date) {
    //add code here
  $dateMatches = explode('/',$date);
  if(count($dateMatches) != 3 ||
     strlen($dateMatches[0]) != 4 ||
     strlen($dateMatches[1]) != 2 ||
     strlen($dateMatches[2]) != 2
  ) {
     return false;
  }else return true;
}

Hi you can add some additional checking to check if the date is numeric because the checkdate function will throw a notice.
Basically this is how you can do it:

<?php
function valid_sql_date($date) {
    //add code here
    $parts = explode('-', $date);
    $year = $parts[0];
    $month = $parts[1];
    $day = $parts[2];

    if(checkdate($month, $day, $year))
        return true;

    return false;
}
