6,593 PointsChallenge 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?
<?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));

54,969 PointsFrom 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]))
