Challenge task not admitting my function works

<?php

function valid_sql_date($date) { $datematch = explode('-',$date); if ( (strlen($datematch[0]) != 4) || (strlen($datematch[1]) != 2) || (strlen($datematch[2]) != 2) || (!checkdate($datematch[2], $datematch[1], $datematch[0])) ) { return false; } else { return true; } } $d = "1996-08-08"; echo var_dump(valid_sql_date($d));

This is my code. Works in the preview, returns bool(true), and false if I enter an invalid date. So why wont the challenge accept it?

index.php 
<?php

function valid_sql_date($date) {
  $datematch = explode('-',$date);
  if ( (strlen($datematch[0]) != 4) || (strlen($datematch[1]) != 2) || (strlen($datematch[2]) != 2)
            || (!checkdate($datematch[2], $datematch[1], $datematch[0])) ) {
    return false;
  } else {
    return true;
  }
}
$d = "1996-08-08";
echo var_dump(valid_sql_date($d));

From the PHP docs on checkdate

checkdate ( int $month , int $day , int $year ) : bool

If the date is in format YYYY-MM-DD then you have the day and month reversed. Try:

(!checkdate($datematch[1], $datematch[2], $datematch[0]))
