php check for a valid date, weird date conversions

Question

Is there a way to check to see if a date/time is valid you would think these would be easy to check:

$date = \'0000-00-00\';
$time = \'00:00:00\';
$dateTime          


        

Answer 1

I have used the following code to validate dates coming from ExtJS applications.

function check_sql_date_format($date) {
    $date = substr($date, 0, 10);
    list($year, $month, $day) = explode('-', $date);
    if (!is_numeric($year) || !is_numeric($month) || !is_numeric($day)) {
        return false;
    }
    return checkdate($month, $day, $year);
}
