Question

I’ve got this so far:

$post_dob = '19/08/1982';                      
$pattern = '/^\[0-9]{2}\/\[0-9]{2}\/\[0-9]{4}\$/';


if(!preg_match($pattern, $post_dob)){                                
    $post_dob = explode('/', $_POST[$field]);
    $post_dob = $post_dob[2] . '-' . $post_dob[1] . '-' . $post_dob[0];  
    return $post_dob;
}else{
    return false;
}

It doesn’t seem to go wrong if i put 19/08/19823123
Any ideas what I’m doing wrong?

Answer 1

Try

$pattern = '@^[0-9]{2}/[0-9]{2}/[0-9]{4}$@';

But in reality, its much complicated than that. You’ll have to consider leap years and months having 30 days versus 31 days, etc.
