What am I doing wrong?


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

Hi Roger!

I think that order of parameters in function



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

If you output contents of your array after explode


You will notice that

$dateMatch[0] - Year
$dateMatch[1] - month
$dateMatch[2] - date

In your case try following

checkdate($dateMatch[1], $dateMatch[2], $dateMatch[0]);

Hope this will help.

Best regards.
